摘要
为解决某些果树树种繁育困难的问题,研制了半日光间歇弥雾果树育苗系统,用于甜樱桃矮化砧木吉塞拉6号嫩梢扦插育苗。通过对育苗环境主要因子的宽范围高精度调控,45d育成新苗,生根率93.66%以上,每株平均生根7.29条,新苗移栽成活率95%以上。与传统扦插育苗和组培繁育相比,育苗周期和成本均显著降低。
To overcome the difficulties in some fruit trees rapid propagation,a partial-sunlight intermittent misting system was designed and used in the new shootings of the sweet cherry dwarf rootstock Gisela 6 with softwood cutting.In conditions of controlling the environmental factors accurately in the greenhouse,the rooting rate of the new shoots reached to 93.66% in 45 days and the average number of roots was 7.29.The survival rate of the new shoots was up to 95%.Compared with the traditional tissue culture and rapid propagation,the technique can shorten the propagation period and cut down the cost distinctively.
