Participation of H_2O_2 in Enhancement of Cold Chilling by Salicylic Acid in Banana Seedlings

The possible physiological mechanism of enhancement of cold tolerance by salicylic acid (SA) in banana seedlings ( Musa acuminata cv. Williams 8188) was explored. Measurements of leakage electrolyte after 2 d of recovery at 30/22 ℃ (day/night) following 3 d of cold stress at 7 ℃ showed that pretreatment with hydroponic solution containing SA 0.3-0.9 mmol/L as foliar spray under normal growth conditions (30/22 ℃) could significantly enhance cold tolerance of banana plants. The highest enhancing effect of SA occurred at 0.5 mmol/L and it showed the lowest leakage rate of electrolyte or smaller leaf wilting area after 2 d of recovery at normal temperature from 3 d of 7 ℃ or 5 ℃ cold stress. Higher concentrations (≥2.5 mmol/L) of SA, however, caused more electrolyte leakage, indicating that they aggravated chilling damage. Enhanced cold tolerance by SA could be related to H 2O 2 metabolism. Compared with water_treated seedlings (control), SA 0.5 mmol/L treatment inhibited activities of catalase (CAT) and ascorbate peroxidase (APX), increased peroxidase (POX) activity, but did not affect the activity of superoxide dismutase (SOD) under normal growth conditions, and these changes might lead to an accumulation of H 2O 2, whereas SA pretreatment enhanced the activities of CAT and APX, and reduced the increase in productions of H 2O 2 and thiobarbituric acid_reaction substances (TBARS) during subsequent 7 ℃ cold stress and recovery periods. Exogenous H 2O 2 treatments (1.5 -2.5 mmol/L) also increased cold tolerance of banana seedlings. Furthermore, pretreatment of banana seedlings with dimethylthiourea (a trap for H 2O 2) significantly inhibited cold tolerance induced by SA. These results suggested that endogenous H 2O 2 may be required for SA_enhanced cold tolerance. The significance of the interaction of SA, H 2O 2 and H 2O 2_metabolizing enzymes during cold stress has been discussed.

Inheritance of Aroma of Good-quality Indica Type Rice PTGMS Line GHS and Its Application in Hybrid Rice Breeding

The inheritance of aroma of GHS was studied by crossing GHS with non-aromatic lines 9311, Xianhui 207, Yuefengzhan, Taihuangzhan, Yuexiangzhan and aromatic lines Yuxiangyouzhan, Xiangwanxian 17, Tianlongxiang 103, Xinwanxiang and Chuangxiang 5. For the grains of F1 generation, the performance of aroma was tested by chewing method, while for the plants of generations of F1, F2 and BC1 F1, the performance of aroma was tested by KOH solution method. The results showed that the non-aroma of restorer line is a dominant trait, but the aroma of GHS line is a recessive trait; the aroma genes of GHS, Yuexiangzhan and Xiangwanxian 17 were non-al elic; the aroma genes of GHS, Yuxiangyouzhan, Tianlongxiang 103, Xin-wanxiang and Chuangxiang 5 may have the same al elic loci. Among the combinations of GHS and non-aromatic restorer lines, the non-aromatic to aromatic ratios of the F2 plants and the BC1 F1 plants were 3∶1 and 1∶1, respectively, and the inheritance of aroma of GHS was control ed by a pair of recessive nuclear genes. In hybrid rice breeding, using GHS, Qiongxiang S has been bred out, and a series of aro-matic hybrid rice combinations have also been selected. Among the hybrid combi-nations, Qiongxiangliangyou 1, Qiongxiangliangyou 2 and other high-yielding and high-quality combinations have been approved by provincial government, and they have good application prospects.

Study on Processing of Clear Banana Juice Using Hot Water Extraction Method

In this study, the effects of hot water temperature on clarity, total soluble solids, polyphenol oxidase （PPO） and color of banana juice during hot water ex-traction were discussed based on the theory in which heat treatment might induce the pectin and protein in banana pulp to form insoluble products. The results showed the hot water temperature had a significant effect on the formation of insol-uble polymers in banana pulp from pectin and protein. In 75 ℃ water, the pectin and protein in banana pulp were most inclined to form insoluble products. Under this condition, the clarity of banana juice was also highest. The light transmittance at 660 nm was close to 90%. In the banana juice, extracted by 75 ℃ water, the pectin and protein contents were lowest, and they were lower than 7.3 mg/100 ml and 12.9 mg/100 ml respectively. The 75 ℃ water could not inactivate completely the pectin in banana pulp due to its high heat resistance, Therefore, 0.05% L-cys-teine or ascorbic acid needed to be added into banana pulp to inhibit the browning of juice induced by residual PPO.

Effects of Regulated Deficit Irrigation on Twig Water Potential of Korla Fragrant Pear

With 7-year-old Korla fragrant pear trees as the experimental material, different root-zone irrigation patterns were arranged to study the effects of soil moisture on twig water potential of Korla fragrant pear trees at different growth stages. The results showed that under the condition of regulated deficit irrigation, the diurnal dynamics of twig water potential of Korla fragrant pear trees was V shaped at different growth stages, and the twig water potential of Korla fragrant pear trees reached the minimum during 14：00-16：00. At different growth stages, the twig water potential of Korla fragrant pear trees under drought stress was significantly lower than that of pear trees irrigated normally. Under both drought stress and normal irrigation, the diurnal variation of twig water potential of Korla fragrant pear trees during the flowering period was most gentle, that during the fruit-setting and mature periods showed some ups and downs, and that during the fruit enlargement period was greater. Under the experimental conditions, the twig water potential of Korla fragrant pear trees was positively correlated with soil moisture content, and the functional relationships between them at different growth stages were studied by regression analysis. In addition, the limits of twig water potential and soil moisture content for normal growth of Korla fragrant pear trees at different growth stages were determined.

Persistent and advanced reddening of sweetgum leaves after major veins severing

The effects of major veins severing on morphological and physiological features of sweetgum （Liquidambar styraciflua L.） leaves were investigated by observing leaf color change and measuring leaf temperature, green/luminance （G/L） value of half-lobes, leaf stomata conductance, and water content in Yamaguchi University, Japan. The palmately veined leaves of sweetgum （Liquidambar styraciflua L.） were found more sensitive to the major vein severing than that of other species Major veins severing resulted in serious water stresses, as indicated by the persistent reddening and/or advanced reddening of local leaf, lower leaf stomatal conductance, and higher leaf temperature, etc. Severed leaf can be clearly divided into non-severed area, transitional area, and stressed area, which the three areas have different colours and temperature. The major vein barrier can also be seen clearly. The persistent reddening and advanced reddening seem consistent with the phenomenon of red crown top of some sweetgum trees and may have similar mechanism.

Aromatic Compounds Production from Sorbitol by Aqueous Catalytic Reforming

The rules on regulating aromatic compounds production was investigated by aqueous cat- alytic reforming of sorbitol. It was found that aromatics, ketones, furans, organic acids were main compounds in organic phase. The obvious effect of metal content showed that the highest carbon selectivity of aromatics was 34.36% when 3wt% Ni content was loaded on HZSM-5 zeolite modified by MCM-41. However, it was decreased only to 4.82% when Ni content was improved to 20wt%. Meanwhile, different reaction parameters also displayed important impacts on carbon selectivity. It was improved with the increase of temperature, while it was decreased as liquid hourly space velocity and hydrogen pressure was increased. The results showed that appropriate higher temperature, longer contact time and lower hy- drogen pressure were in favor of aromatics information, which suggested a feasible process to solve energy crisis.

Study on Desiccation and Collection Models for Banana Stems

In this study, 8 kinds of desiccation models and 3 kinds of collection models were studied for banana stems. The results showed that the crushing-com- pression-air drying processing model showed the best desiccation effect for banana stems. Under this desiccation model, the moisture content was reduced from 90.5% to 19.93% with weight reduced by 75.2%; after 3 to 6 months of storage, the mois- ture content was still remained within 17%-20%, and the volume was decreased to 30%-40% of the original volume of fresh banana stems. This desiccation model made banana stems basically meet the requirements by drying storage. The plant- cutting down-crushing-compression-transportation-desiccation-storage production model was initially developed for desiccation and collection of banana stems, which would lay a certain foundation for the utilization of banana stem resource by enterprises.

Seasonal Gametogenesis of Host Sea Anemone(Entacmaea quadricolor) Inhabiting Hong Kong Waters

Studying gonadal development of annual cycle can reveal the process of gametogenesis and reproductive period, and evaluate fertility and source utilization of a species. Host sea anemones are conspicuous members of tropical and subtropical reef ecosystems, but little is known about its biology including reproductive seasonality. Here we reported a one-year study on the gametogenesis and reproduction of host sea anemone(Entacmaea quadricolor) inhabiting Hong Kong waters. E. quadricolor tissues were sampled in 12 occasions from 5 m and 15 m depths of water, respectively. Histological sectioning of the tissues showed that E. quadricolor was dioecious, and populational ratio of female to male was 1:1.6. The gonadal development was asynchronous within an annual cycle, which included proliferating, growing, maturing, spawning, and resting stages. The spawning occurred between August and October when surface seawater temperature reached the annual maximum(28℃), suggesting that temperature is an important factor modulating the gonadal development and mature of E. quadricolor.

Properties of Aroma Sustained-release Cotton Fabric with Rose Fragrance Nanocapsule

The aroma sustained-release cotton fabric was prepared by finishing rose fragrance nanocapsules directly on cotton.The structure and properties of nanocapsules were demonstrated by transmission electron microscope(TEM),dynamic light scattering(DLS),fourier transform infrared spectrometer(FTIR),X-ray diffraction (XRD),gas chromatography-mass spectrometry(GC-MS)and electronic nose.The results showed that the spherical nanocapsule dispersed evenly and the average diameter kept 51.4 nm.The existence of COO peak(1741 cm? 1)in the FTIR curve of the finished cotton fabric and the decrease of crystallinity demonstrated that rose fragrance nanocapsules have been incorporated into the cotton fabrics.The washing resistance of the cotton fabrics finished by 51.4 nm nanocapsules was much better than that by rose fragrance alone.Besides,the loss of fragrance from the cotton fabrics finished by 51.4 nm nanocapsules was obviously lower than that by 532 nm nanocapsules and rose fragrance.The smaller the nanocapsule size,the better the sustained release property.Electronic nose analysis also displayed that the aroma released from the cotton fabrics finished by nanocapsules after washing has no obvious variety in contrast to that without washing.The cotton fabrics finished by nanocapsules has the excellent sustained release property.

Antimicrobial Oil-in-Water Nanoemulsions： Synergistic Effect of Nisin and Carvacrol against Bacillus subtilis

The aim of this study was to elucidate the mode of action of two antimicrobial compounds, nisin, which is hydrophilic, and the lipophilic compound carvacrol. For that purpose, both antimicrobials were loaded into Oil-in-/Water nanoemulsions, and their antimicrobial activity against Bacillus subtilis was investigated. The experimental results indicated that the O/W nanoemulsions loaded with both, nisin and carvacrol, having Sauter mean diameter （d3,2） of around 120 nm, were considerably stable under the conditions investigated （up to 1 week storage at room temperature）. The interfacial tension between nisin aqueous solutions and soybean oil could be reduced up to 12 mN/m, as compared to that of pure water and soybean oil （21 mN/m）, so that demonstrating the potential of nisin to be used as emulsifier. The results obtained for O/W nanoemulsions loaded with both antimicrobial compounds indicated a reduction of nearly two log cycles （around 100 times） on B. subtilis population upon incubation for 24 h, compared to the blank （10 mM phosphate buffer）.

Distribution and characterizing sources of polycyclic aromatic hydrocarbons of surface water from Jialing River

Sixteen priority polycyclic aromatic hydrocarbons(PAHs) in surface water samples were analyzed by gas chromatograph-mass spectrometer(GC-MS) to study their distribution and characterizing sources.The water samples were collected from five sites(J1-J5) in the Jialing River of Chongqing downtown area from September 2009 to August 2010.The results demonstrate that the concentration of total PAHs in three samples upstream are relatively higher than those in other two sites downstream,with average concentration of total PAHs for each site ranging from 811.5 ng/L to 1585.8 ng/L.The 2,3 and 4-ring PAHs for sampling stations account for 13.0%,56.6% and 28.6%,respectively,in total PAHs.There are obvious tendencies of seasonal change for PAHs concentration in surface water.The PAHs concentration in April of wet season is 1 301.6 ng/L,which is 1.3 times the lowest amount of total PAHs in August of flood season.Ratios of specific PAH compounds were used to characterize the possible pollution sources.Experimental results indicate that the PAHs in surface water samples are primarily from pyrolytic PAHs because of factories along these sites,while the direct leakage of petroleum products may be significant for two sites,Jiahua Bridge(J4) and Huanghuayuan Bridge(J5),because of the wharf boat nearby.
