breeding cycle 中文意思是什麼
breeding cycle
解釋
繁育周期-
Gene engineering technology is more superior than the cross breeding and directive breeding technology with its short cycle, low cost and high benefit. though traditional breeding technology has been used for a long time. now the direct reports for the changes of the flower color by the chi ( chalcone isomerase ) gene are a few what we known.
關于花色結構基因查爾酮異構酶chi （ chalconeisomerase ）基因對花色改變的直接報道很少，因此，本論文選用了chi基因為目的基因，以純深紅色和純白色矮牽牛（ petuniahybidavilm . ）為材料，研究了chi基因的共抑制和反義抑制以及表達產物增加對花色改良的作用，並在花色改變植株中首次觀察到花器官變異。 -

Abstract : techniques of apple genetic transformation can improve apple trees and shorten the breeding cycle by molecular methods. in the last years, great progress has been made in this field, which involves a number of important apple genotypes developed. so far, apple genetic ransformation mainly adopts agrobacterium - mediated technique, involving infection and transgenic tissue regeneration, which are important steps to affect the transformation efficiency. the initial work to the date is to know and to search for the factors which can increase the efficiency
摘要蘋果的遺傳轉化技術通過分子手段改良蘋果，有助於縮短其育種周期.最近十年，在該領域的研究取得很大進展，涉及到一些重要的蘋果基因型及有用的外源基因.迄今，蘋果的遺傳轉化主要採用農桿菌介導法，侵染與轉化材料的再生是影響其轉化效率的關鍵過程，了解其影響因素，尋找有利因素以提高轉化效率是目前蘋果遺傳轉化研究的重點。 -
