皱叶醉鱼草种子细小 ,千粒重仅 0 .0 2 3g。在温度 2 0～ 2 5℃下第 15d ,其发芽率达 88%以上。在皱叶醉鱼草发芽适温 2 0℃下 ,12 0 0～ 30 0 0lx的人工光照和每日光照 12～ 16h促进种子发芽提前 2～ 3d。在抑制皱叶醉鱼草种子发芽的30℃高温下 ,人工光照长短和不同光照度对皱叶醉鱼草种子发芽有明显的促进。
Wrinkled leaves Buddleia small seeds, 1000 weight only 0. 023g. At the temperature of 20 ~ 25 ℃ 15d, the germination rate of more than 88%. Artificial light of 12 0 0 ~ 30 0 0 lx and daily light of 12 ~ 16 h promoted seed germination 2 ~ 3d ahead of the budding bud of Buddleja mellea. Under the high temperature of 30 ℃, which inhibited the germination of Kikuyuji, the artificial light intensity and the different illumination intensity obviously promoted the germination of the Kikuyuji jujube seed.
