摘要
为探索研究辣椒果实的生长发育规律及营养竞争对果实生长的影响,选用彩椒黄星1号、辣椒洛椒8号为试材,研究了果实的纵横径增长、体积变化、果实鲜重变化规律等。结果表明,辣椒果实的生长发育动态呈S型曲线变化,其生长发育过程大致分为三个时期,(1)缓慢生长期,始花至花后13d左右,果实生长较缓慢;(2)迅速生长期,花后13d至花后32d,果实生长迅速;(3)缓慢生长期,花后32d至采收,生长速度减缓。
The dynamic changes of the fruit volume and fresh weight of Huangxing No.1 (sweet pepper) and Luojiao No.8 (hot pepper) were studied in order to research into the growth rhythm of pepper fruit and the effect of competition for nutrient on the fruit growth. The results showed that the development process of pepper fruit could be approximately divided into three periods. The first period was the first 13 days after flowering in which the fruit grew slow. The second period was from the 13th day after flowering to the 32nd day after flowering in which the fruit grew rapidly. And the last period was from the 32nd day after flowering to harvest in which the fruit grew slow again.
