以红栗2号品种为试材,研究了板栗总苞及坚果的发育特征。结果表明,红栗2号总苞形态发育总体呈逐渐加快趋势;总苞鲜重在8月10日前增长缓慢,后期增重加速,尤其自8月24日至成熟,该阶段增长幅度最大;干物质在生长前期积累相对缓慢,在生长后期尤其是成熟前20天左右积累相对较快。坚果形态发育总体在7月20日前发育迟缓,7月下旬至8月底增长明显,成熟前15天发育放缓;坚果总苞鲜重增长趋势与苞皮鲜重增长相反,总体呈前慢后快趋势;坚果干物质含量在7月底前增长较为缓慢,自8月初至果实成熟增速明显加快。
Taking Hongli No.2 variety as test material, the developmental characteristics of chestnut involucre and nut were studied. The results showed that the morphological development of the total bud of Hongli 2 was gradually accelerated. The fresh weight of the total buds increased slowly before August 10 and accelerated at the later stage, especially from August 24 to mature, Accumulation of material in the early growth stage is relatively slow, especially in the late 20 days before maturity, the accumulation is relatively fast. The morphological development of the nuts generally lagged before July 20, and increased significantly from the end of July to the end of August, and slowed down 15 days before maturity. The fresh weight growth trend of the nuts was opposite to that of the fresh weight of the bracts, Trend; the dry matter content of nuts increased more slowly before the end of July, and the growth of fruit maturity accelerated obviously from the beginning of August.
