本研究的目的是探讨能否通过照射葡葡柚成年树的芽,加快诱发突变系,育成稳定的、结无籽果实的突变无性系,改良果实的品质及结果的特性。如果此项研究获得成功,可利用该技术缩短育成无籽葡葡柚品种的时间,并减少试验植株群体的数量。材料和方法1973年6月4日,从13年生的“Foster”葡萄柚植株(由株心胚长成)上剪下一些直径4—6mm、长12—5cm、有4—6个芽的枝条。将其叶片剪掉,并将平均含水量为62.3％的枝条冼净,装入充气塑料袋,放在4℃冰箱内。次日将其以~(137)Csγ射线(3.3kR/min)处理,每处
The purpose of this study was to investigate whether the quality of the fruit and the quality of the fruit can be improved by irradiating the bud of an adult tree with grapefruit grape, accelerating the mutation-induced line, breeding a stable mutant seedless mutant clones. If this research is successful, this technique can be used to shorten the time to bred grapeseed grapefruit varieties and reduce the number of test plant populations. Materials and Methods On June 4, 1973, from a 13 year old “Foster” grapefruit plant (grown from a plantarrow embryo) cut a few of 4-6 mm in diameter, 12-5 cm in length, 4-6 shoots . The leaves were cut off, and the average water content of 62.3% of the branches clean Xian, into plastic bags, placed in 4 ℃ refrigerator. The next day it was treated with ~ (137) Cs gamma rays (3.3 kR / min) each
