近年来,国内外向日葵的种植面积不断扩大,世界范围内,其油用量已超过菜籽油,仅次于大豆而居第二位。向日葵是异花传粉植物,有的品系有自交不亲和性,是典型的虫媒花,必须要有昆虫帮助传粉,才能很好结实。传粉的昆虫中,有的与向日葵是互利的,有的有利有弊,有的却是无利而有害。另外,昆虫采访,也带来了生物学混杂,使向日葵品种纯度的保持存在很大困难。因此,国内外不少学者对昆虫采访和向日葵结实的问题作了多方面的研究。
In recent years, the planting area of sunflowers at home and abroad has been continuously expanding. Its oil consumption has exceeded that of rapeseed oil worldwide, ranking the second only to that of soybean. Sunflower is a cross-pollination plant, and some strains of self-incompatibility, is a typical insect flower, you must have insects to help pollination, can be very strong. Pollinating insects, and some sunflowers are mutually beneficial, and some pros and cons, but some are unprofitable and harmful. In addition, insect interviews, but also brought a mixture of biology, so that the maintenance of purity of sunflower varieties there is a big difficulty. Therefore, many scholars at home and abroad made a multi-faceted study on the issues of insect interview and sunflower robustness.
