1) empty shell
空苞
1.
There existed remarkable interdependencies between contents of endogenous phytohormones and empty shell chestnut.
内源激素的含量与板栗空苞有显著的相关性,正常板栗GA1+3值花后一直上升至25 d出现明显峰值,且在花后10 d至25d增加非常明显,空苞板栗GA1+3值没有明显增长,花后GA1+3含量快速上升并达到一定的值有利于板栗胚胎的正常生长。
2.
Some main research progress on empty shell formation mechanism of Chinese chestnut is reviewed, especially in the respect of fertilization, pollination, embryology, nutrition and ovary developmental physiology.
从授粉受精作用、胚胎发育过程、树体营养供应和子房发育生理等方面评述了中国板栗空苞形成机理的研究进展，并对当前提高板栗单产的主要研究方向进行了讨
2) empty shell rate
空苞率
1.
In order to determine optimum pollination time and reduce empty shell rate,isolating pollination by bag and artificial pollination experiments were done,taken Zaodali and Zaobanli in Castanea mollissima Blume as materials.
为确定最佳授粉时期,解决板栗空苞率高的问题,对‘早板栗’和‘早大栗’2个板栗品种进行套袋隔离和人工辅助授粉试验。
3) Empty-shell chestnut
空苞栗
1.
However, although some positive progress has been made and many reports has been published, the physiological mechanism of forming the empty-shell chestnut is still to be clarified.
本文通过空苞栗与正常栗的对比试验和化学调节试验，分别就胚胎发育期子房内源激素含量的差异及其对果实生长的影响、授粉和胚胎发育的生理原因、化学调节的生理机制与调节效果等进行了研究，以期弄清板栗空苞形成与调节的生理机制，为板栗空苞的控制提供理论依据。
4) empty shell chestnut
空苞栗
1.
The contents of endogenous hormones in empty shell chestnut ovary and normal chestnut ovary during the period of embryo development were determined,and the effects of BR,GA 3,PP 333 on the endogenous hormone levels in ovary and top shoot of Chinese chestnut were analyzed by means of enzyme linked immunosorbent assay (ELISA).
应用酶联免疫吸附法 (ELISA)测定了空苞栗子房和正常栗子房胚胎发育期的内源激素含量 ,并分析了BR、GA3、PP333对板栗子房和顶芽内源激素平衡的影响。
2.
No obvious difference of involucre diameter was observed between empty shell chestnut and normal chestnut before the 65th day after bloom (late July).
结果表明 ,正常栗总苞和坚果直径增长呈“双S”曲线 ,空苞栗总苞直径在花后 6 5d(7月下旬 )以前与正常栗没有明显差异 ,从花后 6 5d起一直比正常栗低 ;空苞栗坚果直径在花后 2 5d(6月中旬 )即开始比正常栗低 ,花后 45d(7月上旬 )后其增长停滞。
5) rate of empty buds
降低空苞率
1.
It s a problem all over china that many Chestnuts have empty buds, how to reduce, the rate of empty buds in a subject on which lots of schoolars are doing reseach.
板栗产生空苞是一个全国性的问题 ,如何降低空苞率是很多学者研究的课题 ,本文从缺硼是引起板栗空苞的主要原因入手 ,选定具有代表性的地块 ,以不同的施硼量对降低空苞率、增加产量等因素进行分析研究 ,分析施硼的必要性、确定最佳施硼量 ,以指导生产实践 ,结果表明 ,施硼对降低板栗空苞率、增加产量有明显效果 ,且肥效能持续 3～ 5年 ;板栗施硼时以每平方米树冠投影施入 1 5 g为最佳施硼量 ,增产幅度达 45。
