摘要
以6个不同耐热性能的月季品种在常温和高温下的形态指标、生理指标的变化为对象,研究形态指标、生理指标与耐热性的相关性。结果表明,在高温下,月季品种的形态指标、生理指标比常温下均有不同程度的下降,耐热品种的下降幅度明显小于不耐热品种,且形态表现与生理变化相一致。本文所述的形态、生理指标的变化与月季品种的耐热性直接相关。
the research mainly involved the change of morphological, physiological indexes in 6 varieties of China roses with different ability to heat-tolerance in normal and high temperature. The results showed all of those indexes in the China roses reduced in the high temperature, compared to the normal one, and they decreased more in the heat-intolerance variety than those heat-tolerance ones. At the same time, the physiological indexes were consistent with the morphological indexes. So, the heat-tolerance power of the China roses relates directly to changes of those indexes under high temperature.
