Effects of Agro-Ecological Practices on the Productivity of Orange-Fleshed Sweet Potato (Ipomoea batatas (L.) Lam) and Soil Fertility in the Sudano-Sahelian Zone of Burkina Faso

This study consisted to evaluate the effects of ecological practices on the yield performance of the JEWEL of orange-fleshed sweet potato (Ipomoea batatas (L.) Lam). The study was conducted in a Sudano-Sahelian cropping system (Lantargou, eastern region of Burkina Faso). Agro-ecological practices consisted of the inputs of 3.20 t/ha of compost + 2.45 t/ha of wood ash (CO + WA);4.90 t/ha of wood ash (WA);6.40 t/ha of compost (CO) were compared to control with no inputs (T0). Each treatment was repeated four times. The crop management consisted of plowing, harrowing, raising of ridges with 40 cm height, burying of treatments, transplanting of cuttings, two weeding’s, and using of biopesticide called PIOL for crop protection. Composite soil samples per treatment were also collected at tuber harvest and analyzed to determine the effects of treatments on residual soil fertility. Results showed that the plant heights and diameters under the CO were significantly (P < 0.001) improved by 16% and 12% compared to T0. The WA treatment significantly increased the number of large tubers by 43% (P ≤ 0.01) compared to T0. Total tuber numbers, large tuber numbers and tuber yields of sweet potato under CO + WA were significantly (P < 0.001) and respectively improved by 27%, 50% and 31% compared to T0. All treatments increased soil organic matter, N, P and K contents, and reduced soil acidity compared with those obtained under T0. Soil K content was improved by 39% under CO + WA, and soil N content by 34% under WA compared to T0. Soil C/N ratio under CO + WA was reduced by 20% compared others treatments. But, the CO + WA treatment outperformed by improving residual soil N content by 38%, and the WA treatment by increasing soil K content by 50% compared to T0. In addition, soil pHH2O increased by 1.2 units under WA treatment compared to T0. As conclusion, the application of 6.4 t/ha of compost performed well to improve the vegetative growth of orange-fleshed sweet potato while the inputs of 3.2 t/ha of compost + 2.45 t/ha of wood ash were efficacy to significantly increase the tuber yields and improve the residual fertility of soil.

Preliminary Studies on CPG/Hinf Ⅰ RFLP Groups of Citrus tristeza virus Infected Sweet Oranges in China

Citrus tristeza virus （CTV） causes economically important losses to the citrus industry worldwide. Mild strain cross protection （MSCP） against tristeza has hardly been practised due to mixed infection of different CTV-strains and little background of its molecular biology in China. For better cognition on CTV, 192 sweet orange samples collected from eight provinces （Chongqing, Sichuan, Fujian, Hunan, Guangxi, Yunnan, Guangdong and Jiangxi） were tested by direct tissue blot immuno-assay （DTBIA）, and 158 of them were tested positively, which therefore were subjected to coat protein gene （CPG）/Hinf Ⅰ restriction fragment length polymorphism （RFLP） analysis. Sample bulks were compared between Chongqing and Fujian by some statistical data, including ratios of single infection and mixed infection to local samples, proportions of CTV isolates with single RFLP groups, and rates of each RFLP group. The simplified analysis of samples from the other six provinces were then conducted. This study suggests that CTV isolates with CPG/Hinf Ⅰ RFLP groups Ⅲ and Ⅰ are the main epidemic ones in China, and mixed infection of CTV in fields are popular. Based on observation of severity of stem-pitting symptom in field trees, CTV isolates with CPG/Hinf Ⅰ RFLP groups Ⅲ and Ⅰ caused severe stem-pittings in sweet oranges in China.

Production of Transgenic Anliucheng Sweet Orange(Citrus sinensis Osbeck) with Xa21 Gene for Potential Canker Resistance

Citrus canker, an epidemic quarantine disease caused by Xanthomonas axonopodis pv. citri, has brought a great damage in citrus production worldwide. Herein, a rice PRR （pattern recognition receptor） gene Xa21 together with GUS reporter gene and hygromycin phosphotransferase gene （HPT） was introduced into Anliucheng sweet orange （Citrus sinensis Osbeck） via Agrobacterium-mediated transformation of embryogenic callus. The transgenic calluses were screened on MT basal medium containing hygromycin （HYG） and detected by histochemical GUS staining. The transgenic plantlets were recovered through somatic embryogenesis pathway. The regenerated plantlets were accustomed to and maintained in the greenhouse. The transgene integration of recovered plantlets was identiifed by PCR and Southern blot hybridization. It showed that all the transgenic plantlets tested had undergone single copy integration, the expression of Xa21 in eight different transgenic lines detected by qRT-PCR can be divided into three grades, high for T5 and T6, middle for T4 and low for the rest. The tolerance to citrus canker disease of the three recovered transgenic lines T2, T4 and T6 was assessed by in vitro pin-puncture inoculation. The results showed that all the three transgenic lines conferred improved resistance to citrus canker bacterium infection and the T4 transgenic line displayed the highest resistance. The mechanism and feasibility of rice Xa21 in triggering innate immunity in citrus was brielfy discussed.

Proteomic Comparison Between Leaves from a Red-Flesh Mutant and Its Wild-Type in Sweet Orange

The red-flesh mutant Hong Anliu sweet orange is of high nutritional value due to its lycopene accumulation.Our previous studies on this mutant fruits suggested that photosynthesis and oxidative stress could promote the formation of mutation trait.However,leaf rather than fruit is the major part for some important biological processes such as photosynthesis.In this study,we analyzed the proteomic alteration in leaves of the red-flesh mutant Hong Anliu vs.its wild type （WT）.Ten differentially expressed proteins were identified,of which two were involved in photosynthesis,three in oxidative stress,two in defense,and three in metabolism.The high up-regulation of photosynthetic proteins proved the hypothesis that enhanced photosynthesis could provide and transport more substrates into mutant fruits for carotenoid biosynthesis.Similar to the previous results in fruits,anti-oxidative proteins were highly up-regulated in leaves,suggesting the whole plant of Hong Anliu suffered from enhanced oxidative stress.Proteins involved in defense and metabolism were also identified,and their possible roles in the mutation were discussed.

International Competitiveness of Export of China’s Sweet Orange

Selecting the market share,trade competitiveness index,revealed comparative advantage( RCA),and revealed competitive advantage index( CA),this paper compared the competitiveness of China and large sweet orange exporters,and made an empirical analysis. Results indicate that in terms of the market share,Spain has prominent advantage in competitiveness of sweet orange; in terms of the trade competitiveness index,Egypt and South Africa have higher competitiveness in the export of sweet orange; in terms of RCA and CA,Egypt has absolute international advantage in the export of sweet orange. China’s export competitiveness of sweet orange is much lower than other large sweet orange producers such as Spain,Egypt,and South Africa,and the export capacity is much lower than other large sweet orange producers. In view of current situations,it came up with recommendations for improving export competitiveness of China’s sweet orange,including expanding the market,diversifying the varieties,improving the quality,reducing the costs,strengthening cooperation of fruit farmer cooperatives,and enhancing government support.

Pre-harvest Treatment of Zn ＆ B Affects the Fruit Quality and Storability of Sweet Orange

Physico-chemical composition of sweet orange （Citrus sinensis L.） cv. blood red was determined in relation to different storage conditions and micronutrients application at department of horticulture, Agricultural University Peshawar, Pakistan during 2006-2007 and 2007-2008. The post-harvest quality of sweet orange was evaluated for 60 days storage with 20 days intervals. Fruit were harvested after the foliar application of zinc and boron in two consecutive seasons. The harvested fruits were stored at an ambient temperature （ATS） of 25 ＋ 2 ℃ and at low temperature storage （LTS） of 15 ± 2 ℃ with 60%-70% relative humidity （RH） for 60 days. Sweet oranges stored at LTS maintained better fruit quality than ATS. The foliar application of zinc and boron significantly enhanced fruit juice content, total soluble solids （TSS）, ascorbic acid （AA） and non-reducing sugar （NRS） of fruit. However, fruit juice content, TSS and AA were observed significantly higher, when the fruit was treated with high zinc （1%） and low boron （0.02%）. The percent of weight loss, disease incidence, TSS and reducing sugar （RS） increased with increasing the storage durations. A reduction was noted in fruit juice, AA and NRS with increasing the storage durations.

Evaluation of Kenyan Orange Fleshed Sweet Potato （Ipomoea batatas Lam,） Purees for Functional Food Production

Consumption of functional foods with health promoting benefits and/or disease prevention has been on the increase globally. The study aimed at evaluating the potential of utilizing Kenyan orange fleshed sweet potato （Ipomoea batatas Lam.） for functional food production with aesthetics benefits. Purees from three different varieties of orange fleshed sweet potato （OFSP） were analyzed for nutritional, physicochemical and microbial quality, The findings of the study show that the three purees were all microbiologically safe and of near neutral pH, but differed significantly （P 〈 0.05） in nutrient content （dry matter content, 12.76-28.23%; crude fiber, 1.37-2.90% fresh weight basis （FWB）; 13-carotene, 0.94-9.27 mg/100g dry weight basis （DWB）; starch, 10.20-18.30% FWB ＆ total sugar 27.08-31.76% DWB）. The purees had attractive appearance （ranging from yellow to dark orange）, with varying significantly different spectrophotometer hunters color scale （P 〈 0.05）, and flow ability. Conclusions from the findings show great potential of utilizing the varying properties of OFSP puree to produce enriched functional food products such as probiotic/prebiotic dairy, beverages, bakery and baby foods.

Improved Energy and Sensory Properties of Instant Porridge Made from a Roasted Mixture of Grated Orange-Fleshed Sweet Potatoes and Flour Made from Shredded Sun Dried Cassava

Mozambican diets are often lacking in vitamin A. Orange-fleshed sweet potatoes (OFSP) are rich in beta-carotene, a precursor of vitamin A, but are not easily introduced into the diet as the consistency of the porridge made from OFSP is unappetising. Flour made from roasted cassava (garri) produces a palatable porridge with a high energy density. We propose a simple procedure for producing an instant porridge by roasting grated OFSP with flour from shredded sun-dried cassava (G-OFSP). This is an easily adopted variant of the traditional garri-making process. The consistency of this porridge made from milled G-OFSP (G-OFSPf) was compared to the consistency of porridges made from maize flour (Mf), cassava flour (Cf), OFSP flour (OFSPf) and garri flour (Gf) at 43°C, and then correlated to the perceived characteristics assessed by a sensory panel. The dry matter concentration of the porridges was adjusted to give similar consistency, measured by the maximum force of back extrusion, using traditional maize porridge as a reference. The porridges were additionally characterized by back extrusion force relaxation time. Short relaxation times were obtained for G-OFSPf, Mf and Gf porridges and longer times for Cf and OFSPf porridges, corresponding roughly to the sensory preference. In the sensory test of consistency, G-OFSPf porridge was ranked first, followed by Mf, Gf, OFSPf and Cf. In overall sensory tests comparing G-OFSPf porridge to Gf porridge, G-OFSPf porridge was significantly preferred with regard to all sensory attributes evaluated (p < 0.01). The energy density of the G-OFSPf porridge was 5.6 kJ/ml;the highest of the three most preferred porridges with regard to texture. The preparation of flour from a mixture of grated OFSP and shredded sun-dried cassava improved the perceived porridge consistency, increased its energy density, and its high acceptability would increase the intake of betacarotene.

液体有机肥对冰糖橙土壤肥力及果实品质的影响

为探明液体有机肥对冰糖橙土壤肥力及果实品质的影响,设置不施有机肥(CK)、常规有机肥(CF,固体)、YHY液体有机肥(T1)、YLG液体有机肥(T2)4个处理,研究不同处理对土壤肥力和果实品质的影响。结果表明:与CK相比,施用液体有机肥均能不同程度地提升土壤中的有机质、碱解氮、有效磷和速效钾含量,增加了大于0.25 mm粒径土壤水稳定性团聚体含量,降低了土壤团聚体破坏率,提高冰糖橙果实产量,同时改善果实品质,与固体有机肥有类似的效果。综合考虑肥料成本、土壤改善效果以及对冰糖橙的叶片养分状况和果实品质的影响,液体有机肥在冰糖橙栽培中可以作为固体有机肥的一种短期替代或作追肥使用。

柑橘溃疡病菌胁迫对海南绿橙植株生理指标与抗氧化酶的影响

分析溃疡病菌对海南绿橙植株生长代谢和抗氧化酶系统的影响将有助于研究其在溃疡病菌胁迫下的调控机制,推进抗性品种选育工作。通过盆栽试验,主要研究海南绿橙在溃疡病菌胁迫下的生理代谢变化及关键抗氧化酶的响应。结果表明,溃疡病菌胁迫下,绿橙植株的株高增长量、叶面积均未受到显著影响,但植株鲜重显著下降,且引起绿橙叶片的黄化,其中叶绿素a、叶绿素b含量的下降幅度分别为74.09%、81.75%。在溃疡病菌胁迫的0~72 h,超氧化物歧化酶(SOD)、苯丙氨酸解氨酶(PAL)活性和叶片细胞中的丙二醛(MDA)含量均在胁迫24 h时达到高峰,分别是胁迫前的6.15、5.08、5.60倍,以上指标均高于空白对照;冗余分析(RDA)显示,酶活的变化量与各生理指标保持着较好的负相关关系。综上,溃疡病菌胁迫主要引起绿橙叶片光合色素含量的降低,影响叶片的光合代谢,而SOD和PAL是绿橙植株应对溃疡病菌侵染时的关键抗氧化酶,研究结果将为海南柑橘抗性育种的定向选择提供理论研究基础。
