糖用甜菜是典型的異花受粉植物,一般在隔离的情况下形成很少量的种子。但是,当仔细研究甜菜的授粉过程时便发现许多有意思的和未预料到的现象。在已开的花上首先是花药裂开而在这时不用扩大镜很难看见的很小的柱头是紧闭着。由于花丝的短小花粉以湿的粒状撒落在花内,不久变干。干燥了的花粉被风和昆虫(蜜蜂及其他)带到各地。经过5—6小时花药乾枯而且只是在这以後柱头的裂片才很好地展开,在开花的2—3天内裂片的大小显著增大。柱头受粉的能力一般地能保持3天,而在 Sugar beet is a typical cross-pollination plant that generally forms very small amounts of seeds under isolation. However, many interesting and unpredictable phenomena were found when studying the process of pollination of sugar beet. In the open flowers first anther dehiscence, but at this time without a magnifying glass is very difficult to see the tiny stigma is tight. Short filaments of filaments are scattered in the form of wet granules and soon dry out. Dried pollen is taken everywhere by wind and insects (bees and others). After 5-6 hours anthers dried and only after this stigma lobes spread well, the size of the lobes increased significantly within 2-3 days of flowering. The stigma powder ability to maintain the general 3 days, while at
