香菇柄水提液对油菜种子活力及抗逆性的影响

在室内用生物学方法研究了不同浓度香菇柄水提液浸种对油菜种子活力的影响。结果表明，0.005 g/mL 的水提液浸种对提高油菜种子活力的效果最佳。进一步研究表明，0.005 g/mL 的水提液浸种处理，使油菜种子在4℃低温下的发芽率显著提高，且幼苗经4℃低温胁迫两天后，叶片中的超氧化物歧化酶（SOD）、 过氧化物酶（POD）活性，可溶性糖、 可溶性蛋白及叶绿素含量显著高于对照组，膜脂过氧化产物丙二醛（MDA）含量显著低于对照组，表明香菇柄水提液浸种处理油菜种子可提高其种苗的抗寒性。试验结果还表明，香菇柄水提液浸种处理油菜种子可提高油菜种苗的耐除草剂能力。

Effects of Lentinus Edodes root water-extraction on rape seed vigor and stress resistance

This paper aims at studying the effects of Lentinus Edodes root water extraction on rape seed vigor. The results show that the water extraction soaking treatments significantly improve rape seed vigor. Under 4℃ low temperature stress, the 0.005 mg/L Lentinus Edodes root water extraction treatment significantly increases germination rate of rape seeds, and superoxide dismutase (SOD) activity, peroxidase (POD) activity, soluble sugar content, soluble protein content and chlorophyll content of rape leaves. The content of membrane lipid peroxidation product (MDA) is observably decreased which indicates that the water extraction soaking treatment can functionally improve rape seedlings cold resistance. Furthermore, the ability of herbicide resistance of rape seeds could be enhanced by the 0.005 mg/L Lentinus Edodes roots water extraction treatment as well.
