Pectin contents of pumpkin (Cucurbita moschata) 'Longyuanlixiang' during the ripeness by different pruning methods all increased at first and then dropped. Petin contents in pumpkin fruits under one stem and two stems increased at first and then dropped significantly after 30 d, while petin content under three stems remained stable. Pentose and chronium contents of fruits during the ripeness by pruning had the same trend and increased persistently. Pentose and chromium contents under two stems and one stem were observed to defi-nitely increasedly.Pectin,pentose and chromium contents under two stems were highest any stage.
