以8年生“徐香”猕猴桃为试材,定期测定猕猴桃果实的纵径、横径、鲜重以及体积的变化,研究其果实的生长发育动态。结果表明:“徐香”猕猴桃果实纵横径生长呈逐渐上升的单曲线,表现为快-慢-停3个生长期。快速增长期为授粉后30d之内(5月9日至6月7日);缓慢增长期为授粉后30~124d(6月7日至9月9日);停滞增长期为授粉124d之后。果实鲜重和体积的生长曲线亦呈上升的单曲线。鲜重的生长过程可分为4个阶段:迅速膨大期为授粉后40d之内(5月9日至6月17日),较快增长期为授粉后40~76d(6月17日至7月23日),缓慢增长期为授粉后76~144d(7月23日至9月29日),停滞增长期为授粉144d之后;果实体积生长过程分为3个阶段:快速增长期为授粉后40d之内(5月9日至6月17日),缓慢增长期为授粉后40~139d(6月17日至9月24日),停滞增长期为授粉139d之后。果实纵横径的净增长曲线有3个高峰,且纵横径的3次净增长高峰出现时间相同,依次为授粉后第15天(5月24日)、第53天(7月1日)、第117天(9月2日)。果实鲜重和体积的净增长曲线有4个增长高峰,鲜重的净增长高峰依次出现在授粉后第36天(6月13日)、第73天(7月20日)、第129天(9月14日)、第149天(10月4日);体积的净增长高峰依次出现在授粉后36d(6月13日)、73d(7月20日)、98d(8月14日)、139d(9月24日)。
The 8-year-old “Xu Xiang ” kiwifruit were used as test materials to measure the longitudinal, transverse diameter, fresh weight and volume of kiwifruit fruit regularly to study the fruit growth and development. The results showed that the growth of “Xu Xiang ” kiwifruit fruit showed a single curve with gradual increase, which showed three stages of fast - slow - stop. The rapid growth period was within 30 days after pollination (May 9 to June 7); the slow growth period was 30 to 124 days after pollination (June 7 to September 9); the stagnant growth period was 124 days after pollination. Fruit fresh weight and volume growth curve also showed a rising single curve. The growth of fresh weight can be divided into four stages: rapid swollen period within 40d after pollination (May 9 to June 17), the faster growth period after pollination 40 ~ 76d (June 17 to 7 Month 23). The slow growth period was 76 ~ 144 days after pollination (July 23 to September 29), and the stagnant growth period was 144 days after pollination. The fruit volume growth process was divided into three stages: the rapid growth period was after pollination Within 40 days (May 9 to June 17), the slow growth period was 40- 139 days after pollination (June 17-September 24), and the stagnant growth period was 139 days after pollination. There were 3 peaks in the net growth curve of fruit length and breadth, and the peak of 3 times of vertical growth was the same at the 15th day after pollination (May 24th), 53rd days (July 1st) 117 days (September 2). The net growth curve of fresh weight and volume of fruit had 4 growth peaks, the fresh growth net peak appeared in 36 days after pollination (June 13), 73 days (July 20), 129 days September 14) and 149 days (October 4). The peaks of the net increase in volume were observed 36 days after pollination (June 13), 73 days (July 20), 98 days (August 14) 139d (September 24th).
