在根区和结实区基质分开的液培试验中,研究了根区和结实区的Ca对佛州蔓生营养生长和荚果发育的独立效应。根区Ca水平低时,根区和结实区的Ca对其营养生长和荚果发育均产生着影响,随着根区Ca增至最佳生长的临界水平以上时,不结实的植株变成了正常结实的植株。对液培试验的结果采用沙壤土在温室中进行了 In the liquid culture experiment in which the root zone and the stroma were separated from each other, the independent effects of Ca in root zone and stubble zone on the vegetative growth and pod development in Florida were studied. At the lower Ca level in the root zone, Ca in the root zone and stubble zone had an effect on their vegetative growth and pod development, and as the Ca content in the root zone increased above the critical level for optimal growth, the unframed plants became normal Strong plant. The results of the hydroponic experiments were carried out using sandy loam soil in the greenhouse
