拉肖皂苷C对萝卜、黑豆、松柳芽苗种子萌发及幼苗生长的影响

Effect of Laxogenin C on Seed Germination and Seedlings Growth of Radish,Black Bean and Etchling

以萝卜、黑豆、松柳种子为试材,以蒸馏水为对照,研究了0.001、0.005、0.010、0.050、0.100、0.500mg/L不同浓度的拉肖皂苷C(LG-C)对萝卜、黑豆、松柳种子萌发及幼苗生长的影响。结果表明:0.005、0.500mg/L的LG-C溶液浸种对松柳种子萌发具有显著促进作用,各浓度处理对幼苗苗高均无显著影响;0.050mg/L的LG-C明显促进了萝卜幼苗的生长,幼苗地上部生物学产量增加,维生素C含量明显高于其它处理;0.001mg/L的LG-C对黑豆幼苗地上部生物学产量的增加作用明显,对维生素C含量的增加也有较显著的作用;浓度为0.001mg/L的LG-C对松柳幼苗的根长及须根的生长有明显的抑制作用,而对苗粗和根粗有明显的促进作用,0.005mg/L的LG-C则显著促进松柳幼苗地上部生物学产量的增加,同时有效增加其维生素C含量;试验表明,适宜浓度的LG-C在芽苗菜生产中具有一定的应用价值。

Using radish seed,black bean seed, etchling seed as experimental materials, effect of different concentration of Laxogenin C （LG-C） 0. 001,0. 005,0. 010,0. 050,0. 100,0. 500 mg/L on seed germination and seedlings growth of radish, black bean and etchling were studied. The results showed that 0. 005,0. 500 mg/L treatment significantly increased germination rate of etchling seed,but each treatment had no significant influence on seedling height. 0. 050 mg/L of LG-C was the most favorable to seedlings growth of radish and increased its overground biomass and the content of Vitamin C was higher than that of other treatments;0. 001 mg/L of LG-C particulerly increased the overground biomass and the content of Vitamin C of black bean seedling;0. 001 mg/L of LC-C had an obvious inhibition to the root length and the growth of fibrous roots but a obvious promoting effect to the growth of seedling diameter and root diameter of etchling and the concentration of 0. 005 mg/L of LG-C particularly increased its overground biological yield; At the same time, increased the content of Vitamin C effectively. It showed that the suitable concentration of LG-C had a certain application value in the production of sprout vegetable.
