- 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.
