| 摘 要： | 用筛选出的Ａ，８两种抗寒药剂处理水稻、玉米、黄瓜种子和水稻幼苗，结果表明，Ａ剂１０００倍液的抗寒效果与进口产品脱落酸（ＡＢＡ）１０－４ｕｇ／ｍＬ处理的效果相当，比抗寒剂（中国科学院植物所）１００倍液要好．供试水稻品种８９早２２９和９１－２６４浸种处理，其成苗率比对照分别增加１１．７％和７８．２％；喷雾处理分别增加８３％和８１．３％；灌根处理分别增加８６％和７１．７％．浸种处理黄糯－玉米种子受冻指数减少９２．２％，浸种处理黄瓜种子受冻指数减少７２．１％．

| Abstract: | Crop cold resistant pharmaceuticals(Aand
B)selected was respectively usedto soak both seeds of rice, corn and seedling roots of
cucumber and rice,and also used tospray rice seedling leaves. The effect of pharmaceuticals
A(conc.103 times)got the result si- miliar to that of ABA(conc.10-4times)and better than that of
plant pharmaceutical(conc.102 times).Pharmaceutical A showed apparent effects in soaking or
spraying experiment.Compared with tap water treatment,for 89zao-229 and 91- 264 of rice
variety,the livingseedling plants increaced respectively 11.7%and 78.2%by soaking
seeds,83.9%and81.3%by spraying seedling leaves,86.0%and 71.7%by soaking seedling roots.
The coldinjury index by soaking seeds decreaced 92.9%for corn(Huangnuo No.1)and
72.1%forcucumber(Jinyan No.4). |
