- 以早实核桃“辽核1号”、“香玲”、“辽核5号”为试材,研究不同核桃品种在豫北平原地区果实发育动态规律。结果表明:不同核桃品种果实的纵径、横径和侧径发育在同一时期内均显现出相对快速增长的一致性。但品种间三径生长发育有着明显的差异性。同时也表现出核桃果实三径发育动态相对一致的周期规律性,分为果实迅速膨大期和缓慢增长期2个生长发育周期。5月上旬至6月上旬是果实膨大期,完成果实体积膨大的95%以上。6月中旬至9月上旬处于果实缓慢增长期,果实增大值仅占总体积的5%左右。
- Abstract:
- With precocious Juglans regia L.‘Liaohe No.1’,‘Xiangling’ and ‘Liaohe No.5’ as test material,the growth dynamic law of different varieties walnut fruit planted on northern Henan plain area were studied.The results showed that different varieties of walnut fruit longitudinal diameter,transverse diameter and side diameter growth in the same period had relatively rapid growth of consistency.But the three of diameter growth had obvious difference in different varieties.At the same time the three diameter growth dynamic of walnut fruit also showed relatively consistent cycle regularity.Fruit growth was divided into two development cycles:quickly enlargement period and slow growth period.The fruit enlargement period was from early May to early June completed more than 95% fruit volume expansion.The period of fruit slow growth was from mid June to early September,fruit growing value accounts for only about 5% of the total volume.
