室内快速测定VID_(50)(使种子发芽活力指数下降50%)的剂量值,可作为作物诱变适宜剂量。无性繁殖作物的诱变适宜剂量则可通过室内测定休眠芽条GRD_(60)(使萌芽率下降50%)的剂量值确定。测出了玉米、绿豆、红小豆、黍子、芝麻、大葱、银瓜,以VID_(50)作指标和山楂、玫瑰以GRD_(50)作指标的辐射诱变适宜剂量。 Indoor rapid determination VID_ (50) (seed germination activity index decreased by 50%) dose value, can be used as a suitable crop mutagenesis dose. The appropriate dose for mutagenesis of asexually propagated plants can be determined by measuring the dose of dormant bud GRD 60 (reducing the germination rate by 50%) indoors. The appropriate dosage of radiation mutagenesis of corn, mung bean, adzuki bean, millet, sesame, green onion and silver melon with VID_ (50) as index and hawthorn and rose with GRD_ (50)
