| 摘 要： | 研究了引种至北京进行大棚栽培的5个品种台湾青枣的果实生长发育动态,结果表明:台湾青枣各品种果实的生长发育类型均属于较为典型的"双S"型.台湾青枣果实生长发育可以分为4个时期:第一次快速生长期,第一次缓慢生长期,第二次快速生长期及第二次缓慢生长期;各品种台湾青枣的果实纵径、横径的增长量在各生长发育时期差异显著.但总体看来,花后7、8周是各品种台湾青枣较为集中的果实膨大期,持续4～5周,此期间是水肥管理的关键时期;各品种果实生长动态的差异最终决定了不同的果实性状.

| Abstract: | Dynamics of fruit growth and development of five introduced Zizyphus mauritiana varieties was studied.The results showed:(1) the fruit growth curve was double S-shaped.It could be divided into 4 development phases: The first fast growth phase,the first slow growth phase,then the second fast growth phase and again,the second slow growth phase.(2) In different growth phase,the increase of fruit length and diameter of different varieties were significantly different.But,for all the five varieties,the most important growth period were 7~8weeks after blossom.(3) The different dynamics of fruit growth and development in five varieties lead to the different fruit shapes and characters. |
