1. Without sufficient pollination, the growth of the corn is stunted. 没有充足的授粉,玉米的生长就会受阻。
2. Nevertheless, anecdotal reports of wind pollination in cycads cannot be ignored. 然而,一些关于苏铁风媒传粉的传闻也不容忽视。
3. Furthermore, the structure of most female cycad cones seems inconsistent with direct pollination by wind. 此外,大部分雌苏铁球果的结构似乎与风直接授粉不一致。
4. Bees are a critical part of the food chain because flowering plants depend on insects for pollination and the honeybee is the most effective. 蜜蜂是食物链的重要组成部分,因为开花植物的授粉依赖于昆虫,而蜜蜂是最有效的授粉昆虫。
5. Despite the importance of the honeybee, none of this is evidence of a wide-scale pollination crisis or a threat that is specific to pollinators. 尽管蜜蜂很重要,但这些都不是大规模授粉危机的证据,也不是授粉者特有的威胁。
