摘要
综述了氮素在果树成花过程中的作用,认为氮及含氮化合物是果树成花过程中重要的物质,其影响到果树从营养生长向生殖生长的转化,影响花粉的可育性和雌雄花的比例,影响花的质量。花芽的生理分化及形态分化期间都伴随氮素及含氮物质的波动,不同形态的含氮物质在成花过程中的作用也不同。花芽诱导措施都强烈地影响果树体内氮素及含氮化合物的水平。
Effects of nitrogen on flowering of fruit trees were discussed in this paper,and it was concluded that nitrogen and nitrogenous compounds were important materials in adjusting flowering of fruit trees.They affected the transformation from vegetative to reproductive growth,pollen fertility,male and female flower ratio and flower quality.Nitrogen and nitrogenous compounds were severe fluctuations in fruit trees during flower differentiation,but the function of these in flowering was different.Floral inducting measures all could adjust the nitrogen and nitrogenous compound level in fruit trees.
