天目蜜李果实的生长发育可分为3个阶段:第1阶段从谢花至5月4日,为快速生长期,历时44d,果实纵径与横径分别占成熟果实纵横径的59.48％和48.81％;第2阶段从5月5日至25日,为缓慢生长期,历时21d,果实纵横径分别为成熟果纵横径的11.48％和13.57％,此期为果实硬核期;第3阶段从5月26日至7月1日,为第2次快速生长期,历时35d,果实纵横径分别占成熟果的纵横径的29.07％和37.62％,此期为细胞容积的增大,果实达到最大值。果肉细胞的发育,在果肉不同层次有所差异,以果皮层细胞面积增长最慢。果实生长发育全过程与一般核果类果实发育规律基本相同。为此作者提出了提高天目蜜李产量和质量3条技术措施。
The growth and development of Tianmei plum fruit can be divided into three stages: the first stage from Xiehua to May 4, rapid growth period, which lasted 44d, the vertical and horizontal fruit diameter accounted for 59.48% of the vertical and horizontal diameter of ripe fruit and 48.81%; the second phase from May 5 to 25, the slow growth period, which lasted 21d, the vertical and horizontal fruit diameter were 11.48% and 13.57% of the vertical and horizontal diameter of mature fruit, the period of the hard core of the fruit; the third stage From May 26 to July 1, it was the second rapid growth period, which lasted for 35 days. The vertical and horizontal fruit diameter accounted for 29.07% and 37.62% of the vertical and horizontal diameter of ripe fruit, respectively. During this period, the cell volume increased and the fruit reached Maximum The development of pulp cells, different levels in the pulp vary, the cortical cell area is the slowest growth. The whole process of fruit growth and development is similar to that of common stone fruits. To this end, the author put forward three technical measures to improve the yield and quality of honey.
