新疆鄯善地区葡萄胚挽救苗移栽技术

Transplanting technology of grapevine seedlings from embryo rescue in Shanshan region of Xinjiang

研究了不同基质配比对葡萄胚挽救苗的影响,并选出了MS营养液的适宜浇灌浓度以及不同移栽时间对定植成活率的影响。结果表明:椰糠的加入有利于胚挽救苗的生长,提高了胚挽救苗的移栽成活率;用1/4浓度的MS营养液浇灌胚挽救苗可以在一定程度上促进其生长,提高成活率;胚挽救苗在鄯善的适宜移栽时期为3～4月,移栽过晚时气温过高会影响成活率。

The effect of different transplantation medium,nutrient solution concentration and transplant time on the survival of seedlings from rescue embryo culture was investigated.The results showed that the medium with coir pith was beneficial to the growth and survival of the translated seedlings.Watering with the 1/4MS nutrient solution could improve the growth of seedlings and increase the survival rate of the translated seedlings.The preferable period for transplanting was in March and April at Shanshan region.To late transplanting woule ruduce the tsurvival rate of the seedlings because of the higher temperature.
