17、I now have two small apple trees - one crab, one eating - anornamentalorange tree, a grape-producing vine, two blueberry plants and a weeping pear.(目前,有两棵小苹果树,一棵培育来观赏,一棵培植来食用。还有一株观赏性的橘子树,和一枝食用性的葡萄藤,两棵蓝莓和一棵水灵灵的梨树。) 18、Bu...
Cultivated varieties (cultivars) of this species sold in the United States originate from different areas in China and represent genotypes that have been planted in high densities in residential and commercial areas in the introduced range. The species cannot self-pollinate because of a self-...
Its flowers, fruits, leaves and tree habit are all important ornamental characters. As there has been no research on the selection of superior parents and phenotypic variation, new varieties of ornamental crabapple are mainly selected from open-pollination progeny. In order to explore the ...

unintended consequences in another. A major challenge is to understand the complicated regulation of these pathways in order to fine-tune them in a beneficial way. Gene editing has the potential to clarify the role of individual constituents in conjunction with the production of novel varieties. ...
This is an example of good intentions gone bad. Over time, different varieties, some thought to be sterile, have cross-pollinated to produce fruit, which is spread by birds. One only has to look in natural areas of the city, in disturbed lands and woodlands for the narrow, white-blooming...

As editing technologies continue to advance, so too does the ability to generate improved crop varieties with non-transgenic modifications; in some crops, direct transgene-free edits have already been achieved, while in others, T-DNAs have successfully been segregated out through crossing. In ...
To prolong the flowering period, a mixed sowing model of early, middle and later flowering varieties in a ratio of 1:1:1 or 1:3:1 has been applied, and has been shown to achieve higher economic value by prolonging the total rapeseed flowering time (over 5 days, even over 7 days) in...
