植物花冠 花科植物 虫媒传粉植物
font style='font-size:12px;'>
2023/6/14
植物花冠和果实的颜色是长期自然选择的结果，受到虫媒、掠食动物以及环境因素的影响。黄色花冠是一种重要的植物信号，在保障虫媒传粉植物的正常繁殖过程中具有举足轻重的作用。许多重要的农作物，包括番茄和油菜等十字花科植物，具有金黄色的花朵，花色主要由类胡萝卜素积累导致，且类胡萝卜素还广泛存在于橙色和黄色的蔬菜和水果中，如南瓜、甜椒、芒果、橙子等。植物通过何种机制保证自己开黄花呢？

孑遗植物是经历过多次的气候震荡和地质事件而幸存下来的分类群，理解它们如何响应与适应环境变化一直是进化生物学与生态学领域关注的重要科学问题。东亚第三纪孑遗落叶林保存有大量的第三纪孑遗植物，但是目前的全球气候变化对这些物种的生存造成了很大威胁，研究它们如何响应气候变化及其如何适应不断变化的环境，对于全球气候变化背景下的第三纪孑遗植物的保护和管理具有重要意义。
