摘要
研究了芝麻不同种植密度条件下矮化调控对其生长及产量的影响,结果表明:喷施矮壮素能有效降低芝麻株高、始蒴部位,缩短芝麻果轴长度;还能提高芝麻叶片叶绿素含量;但同时也会导致芝麻单株蒴果数、每蒴果粒数的减少,从而使芝麻产量降低。
An experiment was conducted to investigate the effect of chlormequat chloride(CCC)on sesame growth and yield under different planting densities.The results showed that the plant height,initial capsule site and fruit shaft length of sesame were all decreased by CCC.However,the effect of planting density on the above items was little.In addition,chlorophyll content in sesame leaves was increased by spraying CCC,but capsules per plant and seeds per capsule were both reduced,which resulted in reduced sesame yield.
