以杂种榛优良品系:“82-11”(1号)、“84-237”(2号)、“84-402”(3号)为试材,研究榛子果实发育中果实与果仁的增长规律。结果表明:3个品系果实发育均分为3个时期:初始缓慢生长期(果实鲜重增加较慢)、快速生长期(果实鲜重增加较快)、第2次缓慢生长期(果实鲜重增加较慢);果实干重增长分为3个时期:初始缓慢生长期、第1次快速生长期、第2次快速生长期;果仁鲜重的增长可分为2个时期,即快速生长期和慢速生长期。果仁成熟时干重增长速率累积值,1号、2号、3号品系分别为87.50%、96.40%、98.60%。果实鲜重与果仁鲜重,果实干重与果仁干重表现出显著或极显著正相关。
The hybrid hazelnut fine lines: “82-11” (No. 1), “84-237” (No. 2) and “84-402” (No. 3) The law of growth of fruits and nuts. The results showed that the fruit development of the three lines were divided into three periods: the initial slow growth period (fresh fruit weight increased slowly), the rapid growth period (fruit fresh weight increased rapidly), the second slow growth period The growth of fruit dry weight is divided into three periods: the initial slow growth period, the first rapid growth period, the second rapid growth period; fresh weight growth can be divided into two periods, namely rapid growth Period and slow growth period. The dry weight growth rate of nuts at maturity was 87.50%, 96.40% and 98.60% respectively for No.1, No.2 and No.3 lines. Fruit fresh weight and fresh weight of fruit, fruit dry weight and dry weight of nuts showed significant or very significant positive correlation.
