分析结果表明：西农１３７６小麦具有与早熟高产相关的一系列生物学特性，表现在；（１）单位面积有较多的粒数，千粒重较大，亩穗数与穗粒数互补性强；（２）穗分化快，二棱期持续时间长，抽穗早；（３）植株有较好的受光势，叶片长度适中，功能期长．叶片光合强度及单叶净光合量在灌浆初期显著大于高产品种陕２２９；（４）穗分化期对日照敏感度低；（５）茎秆坚实，抗倒伏，抗逆性强． The results showed that: Xixin 1376 wheat has a series of biological characteristics related to early maturity and high yield, which is manifested in the following aspects: (1) the number of grains per unit area is larger, the grain weight is larger, and the number of ears per acre is more complementary to the number of grains per spike; (2) Spike differentiation is fast, the duration of two-ridged period is long, heading is early; (3) The plants have good light-receiving potential, moderate leaf length and long functional period. The leaf photosynthetic intensity and net photosynthetic rate of single leaf were significantly higher than that of high-yielding cultivar Shaan 229 at the early filling stage. (4) The sensitivity to sunshine was low at ear differentiation stage. (5) The stalk was firm, lodging-resistant and resistant to stress.
