摘　　要：以常规砧木枳为对照,研究矮化砧木飞龙枳对尤力克、费米耐劳和菲诺3个柠檬品种树体生长及果实品质性状的影响。结果表明:飞龙枳砧对柠檬树体生长具有显著的抑制作用,株高、冠幅、分枝级数均显著低于枳砧,其挂果期树体高度均在260cm以下;飞龙枳砧能够提升柠檬果实品质,果实可食率、可溶性固形物和可滴定酸含量均显著高于枳砧,而果皮厚度显著低于枳砧;飞龙枳砧柠檬果实的单果重、横径和纵径、果形指数以及维生素C含量与枳砧并无显著差异。Plant dwarfing and fruit quality of 3 lemon varieties （i.e.,Eureka,Femminello,and Fino）grafted on Flying Dragon orange （Poncirus trifoliate （L.）Raft var.monstruosa ）were compared to those on the control rootstock of P .trifoliata （L.）Raft.The lemon trees grown on the Flying Dragon rootstock were significantly reduced on their size,height,crown width,and step branches as compared to control.All of the experimental mature trees with most scions were no taller than 260 cm.In addition,Flying Dragon appeared to improve the quality of lemons with increased edible portion,total soluble solids,and titratable acids,as well as thinner peels.At the same time,the single fruit weight,size,shape or vitamin C contents of the fruits were not affected by the grafting.
