摘要:
为探索北缘地区枇杷果实生长变化规律，给生产管理提供理论参考，以生长在陕西安康的日本品种（编号8#）和当地品种“麦后黄”为试验材料，对果实生长过程生理变化进行研究，结果表明：单果重的增加主要集中在花后90～150 d；呼吸强度在刚坐果时和进入快速生长前处于较高水平，之后逐渐下降；2品种可溶性糖与单果重的变化呈极显著相关（r=0.977 7**；0.953 4**）；可滴定酸和Vc含量以及PPO活性均呈先升高后降低的趋势；POD活性在整个生长过程总体呈波动下降趋势
Abstract:
Two loquat cultivars (No.8, introduced from Japan; Maihouhuang, local variety) that grew in Ankang of Shaanxi were used as experiment materials to study the physiological changes in growth course of fruitage, and explore the growth regularity of loquat fruit under growing conditions in northcultivatedmarginal area. The results showed that the fruit weight increased sharply between 90 and 150 days after anthesis, the respiration intensity reached higher levels at the beginning of fruit setting and before the phase of fast growth, and then subsequently declined gradually, the significant positive correlation was found between the changes of soluble sugar content and the fruit weight (r=0.977 7**;0.953 4**), the vtitratable acid ,Vc content and PPO activity indicated a lowhighlow pattern; POD activity presented a fluctuant downtrend in the whole course of growth.
