我们吃果子总希望少核或无核,尤其是柑桔,无核已成为重要的经济性状之一。三倍体应用在西瓜生产上,培养无籽西瓜。但到目前为止,国内外经济栽培的无核柑桔品种,却没有一个是三倍体。这是因为,柑桔属的多倍体类型无疑可以通过各种途径产生。四倍体芽变可以由于体细胞不平衡而产生;二倍体配子可以由双核花粉母细胞产生,在某些情况下由重组 We always want to eat less fruit or nuclear-free nuclear, especially citrus, a nuclear-free has become one of the important economic traits. Triploid application in watermelon production, cultivate seedless watermelon. But so far, none of the non-nuclear citrus cultivars cultivated domestically and internationally has been triploid. This is because polyploid types of citrus can undoubtedly be produced in various ways. Tetraploid buds can arise due to somatic imbalances; diploid gametes can be produced by the binuclear pollen mother cells, in some cases by recombination
