This study was conducted for the purposes of reducing consumption of wild resources of Paris polyphylla Smith, satisfying the market demand, saving the production cost, improving utilization rate of forest land, increasing income of foresters and protecting ecological environment. Three types of fores{ land, i.e., the evergreen forest land (China fir forest), deciduous forest land (walnut forest) and shrub land (honey suckle forest.) were selected, and seeds and cut rhizomes of Paris polyphylla Smith produced in Bamian Mountain, Hunan, were used in the study on understory seedling raising and cultivation techniques. The results showed that: when using different propagation materials, seed propagation could be adopted to reduce the consumption of wild resources and provide a large number of seedlings, and was beneficial to large-scale planting; and when conducing seedling and plantlet raising followed by transplanting and direct seeding and planting using different propagation materials in large-scale understory cultivation, direct seeding/ planting was appropriate for saving save production cost with the advantage of early production. Among the 3 different types of forest land, the best choice was broad- leaved forest land, which could achieve better economic benefit because of con- forming with the ecological habit and growth and development law of Paris poly- phylla Smith. 展开更多

[Objective] The aim was to seek the optimal choice of hormones,induced temperature,and initial feed for cultivating loach.[Method] Different hormones were injected to Ioaches for artificial reproduction in water at different temperatures.During cultivation,varied initial feeds were put in to explore the optimal choice of hormones,temperature and initial feed.[Result] According to the test,fecundity of female loach is directly proportional to gonad maturity,namely,the higher gonad maturity,the more fecundity.For example,for a female loach whose maturity coefficient was 24%,absolute and relative fecundity rates were 62 142 and 990.In contrast,for a female whose maturity coefficient was 9%,the rates were 18 207 and 367,respectively.The induced effect differs upon hormones and the test demonstrated that LRH-A2 is better in improving fertility rate compared with HCG.For example,the fertility rate in the group with HCG was 78.84 and in the group with LRH-A2 was 83.04%.It is notable that the mixture of the two at a certain ratio would enhance induced effect and the fertility rate can be as high as 89.17%.With temperature in a certain range,the higher temperature,the better induced effect.The test indicated that water temperature at (30±0.5) ℃ is an optimal one and the effect horizon is 6-8 h.In group 4,induced rate was 93.33% and the fertility rate was 89.26%.The research indicated that the survival rate was the highest if wheel animalcule,dominated by Brachionus calyciflorus and Brachionus angularis,was taken as an initial feed,followed by artemia nauplii and corpuscule.In addition,loach fry in the group with yolk and wheel animalcule grew about 1.21 times than the group with only yolk,1.04 times than the group with only fairy shrimp,and 1.1 times than the group with fairy shrimp.[Conclusion] The research provides scientific references for scale loach farming. 展开更多

[Objective] This study was to produce plant seeds on a large scale via sterile germination of the capsules of Dendrobium chrysotoxum and rapid propagation technique.[Method] A large amount of protocorm-like bodies produced from the sterile germination of D.chrysotoxum capsules,were transferred to four different kinds of bud induction media to obtain the optimal media suitable for plantlet differentiation and growth;and then with N6 as basic medium,1.0,1.5 and 2.0 mg/L of NAA and IAA were tested to obtain the optimal media suitable for rooting.[Results] On the medium of MS appended with 1 mg/L 6-BA +10% banana puree + 20 g/L sucrose +6 g/L agar+1 g/L AC,seed germination rate was up to 90%.The optimal medium for differentiation of D.chrysotoxum protocorm-like bodies was N6+ 2 mg/L NAA + 0.5 mg/L 6-BA +10% banana puree + 20 g/L sucrose + 0.5 g/L peptone + 5.8 g/L agar +0.5 g/L AC,grown from which the plantlets were even and orderly in height;and the optimal medium for rooting was N6+1.5 mg/L NAA +10% banana puree + 20 g/L sucrose + 5.8 g/L agar +1 g/L AC,grown from which the plantlets developed more,robust and orderly roots,and their leaves were in dark green color.[Conclusion] Our results provided reference for the rapid propagation of D.chrysotoxum. 展开更多

In this study, we employed a temporary immersion bioreactor(TIB)system for the micropropagation of strawberry seedlings. The TIB method and the conventional method for the micropropagation of strawberry seedlings were compared in terms of explant propagation coefficient, seedling fresh weight,contents of anthocyanins and chlorophyll, and photosynthetic characteristics. The results showed that an inoculation density of 40 explants/L was suitable for the micropropagation of ’Benihope’ strawberry seedlings in the TIB. The propagation coefficient, fresh weight, photosynthetic rate, stomatal conductance, transpiration coefficient, and the contents of total anthocyanins and chlorophyll of seedlings micropropagated in the TIB were significantly higher than those of the seedlings micropropagated by the conventional method. In conclusion, the TIB method was superior to the conventional method in the micropropagation of strawberry seedlings.The negative reciprocity did not occur between anthocyanins and chlorophyll in strawberry seedlings cultured under forced ventilation such as TIB. 展开更多
