摘　　要：烯效唑浸种处理小麦种子后 ,从 1叶 1心期到 4叶 1心期 ,能够极显著地降低株高 ,增加幼苗的分蘖和根冠比 .在正常管理条件下 ,相同浓度烯效唑浸种的小麦质膜透性比对照降低 ,叶绿素含量和根系活力则显著高于对照 .After soaking seed of wheat in the uniconazole solution,tillering and root-shoot ratio of seedling were increased strikingly,but seedling height was reduced in the period from one-leaf and one-core stage to four-leaf and one-core stage.After soaking seed in the uniconazole solution with its concertration of 10?mg/L,under normal cultivating conditions,the panetrativity of membrane of leaf was lower than control in seedling stage,but the content of chlorophyll and rooting activity were higher clearly than con...
