在果树学中,许多涉及果实生理的研究,只有在人工控制的环境里,才能获得结实的小植株。AleXander and Woodham 通过空中压条的办法,首次成功地繁殖出了挂果的葡萄小植株,压条最好是在亲本开花后不久即进行,第二年移走生了根的插条,便得到了新的植株。硬枝插条扦插的试验未能成功。可是后来从当年新梢上AleXander在主芽中花芽开始孕育后,取嫩梢插条生根得到成功,插条在温室里差不多生长了一年并且只有25％结了正常的果穗。Mullins实行硬枝单芽扦插,通过去掉花序下的基部叶 In fruit tree science, many studies involving the physiology of fruit show that only solid plantlets can be obtained in artificially controlled environments. For the first time, AleXander and Woodham succeeded in breeding the fruiting grape plantlets for the first time by means of aerial battens, preferably shortly after the flowering of the parent, removing the rooted cuttings the following year and obtaining a new Plant. Hard cuttings cuttings test failed. But later from the shoot on the AleXander in the main bud flower buds began to breed, take the shoot shoots rooted success, the cuttings in the greenhouse almost a year and only 25% of the normal knot ear. Mullins implements a hard shoot single shoot cut by removing the basal leaves under the inflorescence
