Effect of Cold Stress on Some Physiological Indexes of Plants in Malvaceae

冷胁迫对锦葵科植物部分生理指标的影响研究(英文)

The paper was to study the change trend of the physiological indexes in plants of Malvaceae under normal and low temperature condition.The result showed that the increase extent of electrical conductivity of plants with cold tolerance in Malvaceae was significantly lower than the plant without cold tolerance under the cold stress condition,while their proline contents and soluble protein contents were all higher than the plants without cold tolerance.The above physiological indicators all can be used for the screening of varieties with cold tolerance in Malvaceae,which will also provide theoretical guidance for the cold tolerance screening of other garden plants.

锦葵科植物研究正常温度和低温条件下锦葵科植物品种部分耐冷生理生化指标的变化趋势。结果表明锦葵科植物耐冷品种在冷胁迫条件下电导率上升明显小于不耐冷品种,而脯氨酸含量、可溶性蛋白含量均比不耐热品种高。上述生理指标均可作为锦葵科植物品种耐冷性筛选指标,也为其他园林植物的耐冷筛选提供理论指导。
