棉花“蕾而不花”症
the failure of cotton square to flowering
棉花“l而不花”症(th。failuresquare to flowering)棉花因缺硼引起的现蕾不见花,或有花难成铃的生理病害。患病植株出现种种形态症状。 株形症状严重缺硼时,棉株从子叶起即开始出现症状.子叶小而肥厚、色深,子叶叶柄下垂使苗株呈“个”形,与正常苗株子叶柄上挺使成“Y”形明显不同;顶芽受害,伸展不正常,真叶出现延迟;由于顶芽死亡,多量腋芽抽发,分枝及叶片增多,形成矮化型的多头棉;进入蓄期后,因顶芽受害,主茎伸长停滞,基部叶片显著增大,而上部新叶小而皱缩,节间短(见图l),株形紧缩,能现蕾,但幼蕾稍长大即变黄.苞叶张开并萎蔫脱落。 器官症状①叶片。基叶老叶肥厚、of eotton边缘失绿,通常向上或向下卷曲呈杯状。②叶柄。短而粗,表面粗糙多毛,严重时纵向裂开,常呈明显的扭曲状;叶柄有暗绿色环带.其组织肿胀突起,以手指触摸时,有明显的节凸感。纵剖时,肉眼可观察到与环带相应的内部组织为暗绿色,严重时为褐色。从叶柄横切面的光镜照片可看到,细胞变形,排列紊乱,有的破裂,尤以髓部为甚,其中还含有大量颗粒状淀积物。③蕾和花。现蕾少,极易脱落。脱落前苞叶张开似虫蛀状,开花极少.偶有开花的,花冠短缩,花瓣常不伸展;花粉粒生活力差,联苯胺一甲苯酚染色,绝大部分为黄色,而正常花粉粒为红色;扫描电镜观察表明,花粉粒干瘪,似泄气皮球.下陷呈半球形,有些花粉粒上的突刺显著减少,甚到肖失(图2)。④棉铃。由于蕾、花大量脱落,很质变脆、色暗绿无光泽,叶脉突出,严重时叶脉木质化,主脉纵向开裂,甚至坏死;上部新叶,形小,薄而皱缩, 图2棉花缺砒花粉粒崎形 左:缺硼花粉粒下陷呈半球形 右:缺硼花粉拉突刺消失少成铃,少量成铃发育迟缓而畸形,常见的为顶端呈尖钩状,开裂后纤维紧贴于铃瓣边缘。⑤果枝和果节:由于蕾、花、铃的连续大量脱落,果节密而果枝短,总果节 数较正常棉株明显增加。(丈,」武定)图1棉花缺硼株形长相(戒文治摄) (a)正常(b)病株(多头状)218
