据报道,维生素C喷于不育系上,能提高杂交水稻制种田的产量.为了进一步探索维生素C对杂交水稻制种的效应,并探求出最适浓度,我们搞了维生素C的不同浓度的喷射试验.一、材料与方法供试材料用威20不育系.其杂交组合为威优明恢63(V_(20A)×明恢63).采用化学分析用的维生素C粉剂,先配成原液1000ppm,然后
It has been reported that vitamin C sprayed on sterile lines can improve the yield of hybrid rice farming.In order to further explore the effect of vitamin C on hybrid rice seed production and explore the optimal concentration, we have different concentrations of vitamin C Spray test.Materials and Methods The test materials were made from the male sterile line 20 and the hybrid combination was Wei You Ming Hui63 (V20A × Minghui63) .The chemical analysis of vitamin C powder Stock 1000ppm, then
