摘　　要：对国家果树种质福州枇杷圃内251份枇杷种质资源的果实抗逆性(抗锈斑病、裂果病、日灼病和皱果病)进行了调查评价。结果表明:22份种质对这4种生理病害均表现强抗性;41份种质表现较强抗性(对其中3种病害抗性强、1种病害抗性中);9份种质的抗逆性较差,特别是坑本、纳溪早红和杨柳白肉等3份种质仅对日灼病抗性表现中等,对其他3种病害抗性弱;野生种质抗逆性优于栽培种质;红肉类型种质抗逆性优于白肉类型;不同来源地种质资源的果实抗逆性也有一定差异。251 loquat accessions from Fuzhou national fruit germplasm nursery were investigated for the resistance to the fruit russeting,cracking,sunburn and fruit crinkle disease.The results indicated that 22 germplasms showed strong resistance to these four physiological disease;41 gemplasms showed better resistance,which showed strong resistance to three disease and medium resistance to another one;The resistance of 9 germplasms is poor,3 germplasms of which showed medium resistance to sunburn and weak resistance to other three disease（Keng Ben,Na Xi Zao Hong and Yang Liu Bai Rou）;The resistance of wild species was better than that of cultivars,and red flesh germplasm was better than white flesh one;There were some differences in the resistance among the germplasms from different regions.
