Abstract:
In order to determine the best pruning period and method，sixyearold ‘Lyuling’ walnut(Juglans regia L.) were used as test materials，spring and autumn were selected as pruning periods，5 pruning branch diameter，the effect of different pruning periods on starch content in branch of different position were studied.The results showed that the starch content of branch T3 pruning in autumn was significantly higher than that of pruning in spring.The contents of xylem starch of all pruning branches in the autumn were significantly higher than that of pruning branches in spring except for T2 diameter branch.The pith starch contents of T4，T5 in oneyearold branches and T3 in perennial pruning branches in spring were significantly higher than that of pruning branches in autumn.The pith starch contents accumulation of pruning branches in spring were significantly higher than that of pruning branches in autumn.
