【摘要】 为银拖墨兰的培养及生产提供实用技术,研究了叶喷赤霉素对银拖墨兰生长发育及开花的影响。结果表明:赤霉素处理对银拖墨兰有提早抽箭和开花的作用。其中以200mg·L-1赤霉素处理对提前抽箭及开花效果较好。同时,赤霉素有促进叶长和花箭长的作用,也可以提高叶片内的叶绿素含量和POD、CAT活性,其中以赤霉素浓度为150和200mg·L-1处理对提高叶片叶绿素含量、POD和CAT活性效果较好。更多还原

【Abstract】 In order to provide practical technology for Yintuo Cymbidium sinense,the effect of spraying different GA concentrations on growth and flowering of Cymbidium sinense Yintuo was studied.The results showed that GA could advance the flower period,and 200 mg·L-1 GA showed the best effect.Additionally,GA could increase the leaves length and the squid length,the chlorophyll content,POD and CAT activity,150 and200mg·L-1 GA exhibited the best effect.更多还原
