摘　　要：该文从冗余度、库容量及光合强度等方面研究了重穗型杂交稻Ⅱ优6078与产量的关系.结果表明:Ⅱ优6078最佳冗余度比汕优63(CK)降低10.39%,库容量提高11.51%,特别是颖花数提高15.55%;单株叶面积Ⅱ优6078比汕优63高48.57%;Ⅱ优6078叶片全氮、光合色素及叶绿素均较优于汕优63,具有较好高光效特性.Some physiological characteristics of the heavy-panicled hybrid rice Eryou6078 and the cultivar Shanyou63 （control） were compared to study the relationship of these characteristics of Eryou6078 with its super high yield potential. The results showed that optimum RD （redundancy） of Eryou6078 was 10.39% lower than that of Shanyou63; and compared with Shanyou63, Eryou6078 had 11.51% higher sink potential, 15.55% more glumaceous flowers and 48.57% greater leaf area per plant. Eryou6078 was shown to have relatively high photosynthetic efficiency for the total N, photosynthetic pigment and chlorophyll contents of its leaves.
