本文提出了根据地上部生物量积累速度评价草本作物对胁迫因素反应的方法。试验是在模拟干旱、炎热以及两者综合作用的条件下,用抗旱性差异明显的春小麦品种进行的。试验表明,不同品种间生长速度有显著差异。本文提出的方法可在育种的各个阶段选择有益类型中大大减少劳力的消耗。
This paper presents a method to evaluate the response of herbaceous plants to stress factors based on the rate of accumulation of aboveground biomass. The experiment was carried out under the conditions of simulated drought, heat and the combined effect of both, with spring wheat varieties with obvious difference in drought resistance. Tests showed that there was a significant difference in growth rate among different varieties. The method proposed in this paper can greatly reduce labor consumption by choosing beneficial types in all stages of breeding.
