酷暑天,当你用手去摸植物叶片,会发现有的叶子凉凉的,好像随身背着“冰箱”;有的叶子却很烫,好像刚从烤箱里拿出来一样。怎么回事?难道相同的温度下叶片温度竟然不同?蒸腾影响了叶片温度你知道吗?其实,相同条件下叶片温度相差是很大的。那么,是什么原因造成了叶片温度的不同呢?要弄清楚这个问题,我们先来认识一个概念——蒸腾。蒸腾是植物特有的生理过程,具有高效的降 Summer heat, when you touch the plant leaves by hand, you will find some leaves cool, as if carrying “refrigerator”; some leaves are very hot, as if just out of the oven the same. How else? Is the same temperature leaves different temperatures actually? Transpiration affect the temperature of the leaves you know? In fact, under the same conditions the temperature difference is great. So, what is the reason for the difference in leaf temperature? To figure out this problem, let’s first understand a concept - transpiration. Transpiration is a plant-specific physiological process with high efficiency
