摘要
在床面湿度为40%,最高温度在31~41℃时,探索研究光照强度对笃斯越桔离体生根及幼苗生长的影响,采用随机区组设计,重复三次,在扦插基质为泥炭藓,采用28000、12500、1100 lux三个梯度调控光照强度,处理2~3 cm笃斯越桔嫩枝扦插苗,结果表明,在光照强度为12500 lux,温度为36℃时,扦插苗生根率为87.3%,平均苗高为13.81 cm,扦插生根及幼苗生长效果最好。
In this paper,the effects of light intensity on the in vitro rooting and seedling growth of Vaccinium uliginosum were studied.A randomized block design was adopted,repeated three times.Sphagnum was used as cutting substrate.Keep the humidity of seedbed at 40%.The 2-3 cm Vaccinium uliginosum softwood cuttings were treated with 28000 lux,12500 lux and 1100 lux light intensity.The results showed that when the light intensity was 12500 lux,the rooting rate of cuttings was 87.3%,and the average seedling height was 13.81 cm,cutting Rooting and seedling growth were the best.
