摘　　要： 为了探讨地形对龙门年橘留树保鲜过程中果实品质的影响,进行了连续3 a的观测,结果表明地形对年橘留树保鲜果实外观内质均有影响,坡地年橘果实的维生素C含量、可溶性固形物含量、还原糖、蔗糖和总糖含量均高于平地果园,其峰值在2月中旬左右和平地果园同时或稍晚出现,此后含量都出现下降,不同物质的下降速度不同,但不同地形对同种物质下降速度影响不明显。内含物出现峰值前山地果园单叶净光合速率高于平地园,随内含物含量下降,平地果园的单叶净光合速率也逐渐大于坡地园。坡地果园成熟稍晚于平地果园,更有利于留树保鲜。 To study the effects of topography on quality of Longmen Nianju（Citrus reticuiata Blanco） fruits stored on the tree,experiment was made in three consecutive years.The results showed that the orchard＇s topography have a certain impact on the appearance and endoplasmic of fresh fruit on the tree.Vc content,soluble solids content,reducing sugar,sucrose and total sugar content of fruit on plain orchard were more than those on slope orchard.The maximum of those in slope orchard appeared in mid-February in the same time or later than in the plains.Thereafter,the contents of these quality parameters decreased at different speeds,but the topography did not significantly affect them.Before the appearance of maximum,the Pn of leaves in sloping fields were higher than that the plains,but those in the plains increased gradually with the decline of fruit quality parameters.The fruits of slope orchard were available to storage on the tree because they matured later than those in the plain orchard.
