摘要
对哈尔滨地区连续两年对草原樱桃3个品种的新梢和果实生长动态进行详细地观察测定。结果表明,草原樱桃新梢的生长一年中有两次明显的高峰,第1次为6月中旬,第2次为7月上旬,8月初形成顶芽停止生长;草原樱桃果实发育动态是典型的双S曲线,即分为第1次速长期、缓慢生长期、第2次速长期3个阶段。在果实采收前,横径生长明显快于纵径生长,同时鲜重也迅速增加;草原樱桃的新梢生长和果实的发育几乎同时开始,交替进行。
Detailed studies on growth and development dlynamics of shoats and fruit of 3 cultivars of ground cherry were conducted in Harbin for two years in succession The results showed that the shoats presented two peaks of growth during a year. One peak appeared in the middle ten days of June, the other in the first ten days of July. The terminal bud stopped growing in early August. The development of fruit presented a double S curve. It could be divided inro 3development phases: the first fast growth phase, The second one was slow growth phase and the second fast growth phase. Before the harvest of the fruit the longitudinal diameter grewfaster than the cross diameter, and the weight of the fruit increased quicklg The growth of the shoots began almost simultaneously with the development of the fruit, and their peaks in growth appeared alternatively.
