种子活力和产量如果种子活力影响产量,其影响通过某些包括产量生产在内植株生长过程是显而易见的。任何作物产量是由作物群体截获太阳辐射、太阳辐射转换成干物质效率和构成经济产量生物量比例所决定。产量是植株个体、群体、环境和变化环境生长过程总和特性的一种函数。许多作物(如谷类作物),产量被定义单位面积重量,而植株群体是考虑的恰当单位。若产量被定义 Seed Vigor and Yield If seed vigor affects yield, its effects are readily apparent through some plant growth processes, including yield production. Any crop yield is determined by the interception of solar radiation by the crop population, the conversion of solar radiation to dry matter efficiency, and the proportion of biomass that constitutes economic output. Yield is a function of the sum of the characteristics of plant individuals, populations, environments, and changing environmental growth processes. For many crops (such as cereal crops), the yield is defined as the weight per unit area and the plant population is the appropriate unit to consider. If production is defined
