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
