【摘要】 试验比较了江苏3个主要茭白品种正常茭及其雄茭主要性状的差异.结果表明:①正常茭植株叶片还原精含量低于雄茭;叶片叶绿素含量孕茭前低于雄茭,孕后则较高;②正常茭叶片氮、磷元素含量生长前期低于雄茭,以后则较高;钾元素含量仅孕茭初期显著高于雄茭,其余时期均较低;③正常茭茎尖生长点细胞液泡化程度低于雄茭,微体较雄茭少,并无淀粉粒积累.更多还原

【Abstract】 Here is the report of the difference of the character on physiology and biochemistry between unpregnant water bamboo ("male") and normal water bamboo on three main varieties in Jiangsu.The difference included chlorophyll contents, reductive sugar contents, nitrogen, phosphorus and potassium contents in leaves. The results showed that:The reductive sugar contents of the "male" were greater than the normal. The chlorophyll contents were higher before pregnanting period, lower after it. The N. P contents were higher before the middle of June, Lower after it. The K contents were higher in growth period, lower in first pregnanting period, then still higher. These changes of N.P and K were affinity with the growth situation in each treatment. The number and Volume of vacuole in stem growing point cell of the "male" are more and bigger than the normal,the granulous enzyme body is so, and there is the accumulation of starchy granule in unpregnant water bamboo.更多还原
