在一定范围的日平均入射光合量子流量(PPF,50～100μmol/s·m~2)情况下在7年生欧洲李的树冠,测量了单位叶面积干重(LDW/LA),单位叶面积含氮量(LN/LA),叶干重(LDW)和果实品质特别是单位果实含糖量(SF)、果实鲜重(FFW)和果实干重(FDW).测量结果发现在该入射光合量子流范围内,叶片特性与果实特性呈显著的直线或曲线关系,因此我们可以根据对 LDW/LA 或 LN/LA 的分析结果指出树冠中的某些部位,在该部位李果实大小与品质都受到不适宜的 PPF 的限制.
Under the condition of a certain range of daily mean incident photosynthetic quantum flux (PPF, 50 ~ 100μmol / s · m ~ 2), the canopy weight per unit area was measured for the leaf dry weight per unit area (LDW / LA) Nitrogen content (LN / LA), leaf dry weight (LDW) and fruit quality, especially unit fruit SF, FFW and FDW, were measured.The results showed that at the incident photosynthetic quantum Within the flow range, leaf traits and fruit traits show significant linear or curvilinear relationships, so we can point out some parts of the canopy based on the analysis of LDW / LA or LN / LA where the size and quality of the plum fruit are affected Inappropriate PPF limits.
