摘要
以不同浓度的氯化胆碱(CC)处理田间栽培甘蔗。经合适浓度的CC处理的甘蔗叶绿素含量、叶内Mg2+-ATPase和Ca2+-ATPase,NADP一苹果酸酶和磷酸烯醇式丙酮酸(PEP)羧化酶等活性,叶绿体的希尔(Hill)反应活力和光合速率都有不同程度的提高,甘蔗的株高、茎粗、蔗茎含糖量也有所提高。
The sugarcane(Saccharum officinarum)grown in field was sprayed with different concentration of choline chloride (CC),and the growth and some physiological characters of sugarcane were determined.The results showed that the chlorophyll content,the activities of Mg2+-ATPase,Ca2+-ATPase,malic enzyme,PEPCase and the Hill reaction,the rae of photosynthesis in the leaves treated with CC were all increased in various degrees as compared with the control.Thence the plant height,the stalk diameter,the yield and the content of sucrose in stalk were all increased.
