【摘要】 采用烯效唑、B9、水杨酸处理种植在大棚基质中的大西洋脱毒试管苗,比较不同生长调节剂对马铃薯微型薯结薯的影响。结果表明:烯效唑对植株的生长有促进效果,以100 mg.L-1处理具有最佳效果,随着浓度的增加,处理出现的负效果越大;B9喷施的植株单块茎重和总块茎重均以2 500 mg.L-1浓度的处理最高,且大、中大薯在总块茎数所占的比例最大;水杨酸以400 mg.L-1浓度的处理效果最好。更多还原

【Abstract】 Three kinds of growth regulators viz.S-3307,SA,and B9 were used in researching the tuberization of potato minituber.The results showed that the three growth regulators could increase the tuberization.100 mg·L-1 S-3307 was in favor of increasing the quantity of minituber.With the increase of S-3307 concentration,it showed up side-effect.2 500 mg·L-1 B9 and 400 mg·L-1 SA were also the best concentrations for increasing mean tuber weight and total tuber yield.The percentage of big and medium-big potato was also increased.更多还原
