摘 要 ：灌溉条件下，减源可使小麦叶片光合速率增加，减库光合速率降低。增降幅度因品种而异。鲁215953、山农48-2,鲁麦14和莱州953等品种减源后光合速率增加较少，但减库后光合速率明显降低;鲁麦15、核生2 , D041和太780等品种则相反。旱地无灌溉条件下，无论源或者库的调节对小麦叶片光合速率的影响都比较小。说明源库与光合速率之

Abstract:Source abatement decreased leaf net photosynthetic rate(Pn) and sink abatement increased Pn of irrigated wheat. However，the decreased or increased magnitude varied among genotypes. Decreasing source of the cultivars Lu215953，Shannong 48-2，Lumai 14，and Laizhou 953 induced less increment of Pn，b
