KT对菊花形态、生理和花期的影响

在秋菊“金皇后”品种的营养生长期和绿蕾期 ,以一定浓度 ( 1 0mg/L、2 0mg/L和 5 0mg/L)的KT水溶液进行喷雾处理 ,初步研究了KT对菊花绿蕾期叶片和花期花瓣生理生化以及对开花时间、花期长短的影响。结果表明 ,KT处理使菊花绿蕾期叶片叶绿素总含量、还原性总糖 /可溶性蛋白、干重 /鲜重、表观光合速率和呼吸速率均明显高于对照 ;花时比对照提早 1 7.1d ,绿蕾期持续时间缩短 41 .5 0 % ;花期花瓣组织电解质渗漏率低于对照 ,花期持续时间延长 8d ,延长率为 3 1 .3 7%。其中 2 0mg/LKT处理效果最好

Effect of KT on configuration,physiology and the florescence of chrysanthemum

In the vegetable growing and the green bud stage of chrysanthemum“Golden empress”,different concentrations(10 mg/L,20 mg/L and 50 mg/L)of KT was sprayed to study the effect of KT on the leaves of the green bud,physiological and biochemical changes of the petals in the florescence,the time of flowering and the length of florescence of chrysanthemum. Results as follows:In the leaves of green bud stage,the changes of chlorophyll content,Reductive suger/soluble protein,Dry Weight/Fresh Weight,the apparent photosynthesis rate and respiratory rate are separately higher than those of CK.As far as“Golden empress”is concerned,florescence is ahead of 17.1 d;the duration of the green bud stage is 41.50% shorter. The relative electric conductivity of the petals in the florescence is lower than CK,florescence prolongs 8 d,prolonged rate is 31.37%.and KT of 20 mg/L is the best concentration.
