Effects of Different Substrate Ratios on the Growth and Quality of Reproductive Seed of Weixi Glutinous Dioscorea opposita Axillary Bud
摘要
Abstract
Objective:To screen the best substrate ratio suitable for the reproductive seed of Weixi glutinous Dioscorea opposita ax-illary bud.Methods:Using axillary bud of Weixi glutinous Dioscorea opposita as breeding material and grass carbon,coco coir,pine nee-dle humus and sandy soil as raw materials,seedling substrate was prepared,the effects of different substrate ratio on the growth,develop-ment and quality of axillary bud propagation of Weixi glutinous Dioscorea opposita were studied in a greenhouse experiment.Results:The application of different matrix ratio to the seedling cultivation of Weixi glutinous Dioscorea opposita axillary bud promoted the seed growth of Dioscorea opposita,significantly increased the emergence rate of axillary bud,and increased the tuber length,diameter of up-per,middle and lower tubers and fresh and dry weight of Dioscorea opposita.T4[V(grass carbon)∶V(coco coir)∶V(pine needle humus)∶V(sandy soil)=0∶3∶3∶3]treatment of tuber length,diameter of upper,middle and lower tuber and fresh and dry weight of Dioscorea opposita increased most significantly.Compared with CK,they were significantly increased by 95.78%,34.07%,59.15%,27.87%,41.51%and 39.47%(P<0.05).Different substrate ratio improved the quality of Dioscorea opposita,and T4 treatment had the most ob-vious improvement effect,compared with CK,the saponins,starch and ash contents of Dioscorea opposita were significantly increased by 16.98%,12.22%and 13.52%(P<0.05),respectively.The mucous protein was increased by 3.33%than CK and there was no signifi-cant difference in water content among each treatment group.Conclusion:Considering the effect of substrate ratio on the morphological characteristics,yield and quality of Dioscorea opposita comprehensively,the substrate ratio of T4 treatment is the best.The results can provide theoretical support for the large-scale and standardized production of Weixi glutinous Dioscorea opposita.关键词
