| 摘 要： | 熟相是指棉株吐絮成熟期的衰老表现,有正常成熟、早衰和贪青晚熟等熟相之分,实现正常熟相需要协调的库源关系和根冠关系.整枝、嫁接和环割等措施通过改变棉花库源关系和根冠关系,导致细胞分裂素和脱落酸含量发生变化,引起早衰或贪青晚熟等异常熟相.品种自身的遗传背景、栽培措施和外界环境等都可以改变库源关系、根冠关系及相关的植物激素平...

| Abstract: | Maturity performance is termed as senescence performance of a cotton plant during boll opening.Normal maturity performance is obtained only when sink-source and root-canopy is well coordinated.A number of experiments have been conducted to confirm that removal of branches,seedling grafting and stem girding at squaring change sink-source,root-canopy and carbon-nitrogen metabolism.The cytokinins and abscisic acid(ABA) changed accordingly,thus leading to premature senescence or late-maturity performance of cot... |
