试验就ＣＯ2 浓度 ( 35～ 4 50ａｍｂｉｅｎｔ,10 0 0或 2 0 0 0 μｍｏｌ/ｍｌ) ,空气交换速率 ( 0 5或 2次 /ｈ)、温度 2 4± 1℃ ,光合光子通量 (ＰＰＦ 140 μｍｏｌ/ ·ｓ,光周期 16ｈ)和相对湿度 ( 70 %～ 80 % )对非洲菊幼苗生长的影响进行调查。外植体 (芽 )取自光合
The results showed that the photosynthetic photon flux (PPF 140) was the highest in the experiment of CO2 concentration (35-4 50 ambient, 10 0 0 or 20 000 μmol / ml), air exchange rate (0 5 or 2 times / h), temperature 24 ± 1 ℃, μmol / · s, photoperiod 16h) and relative humidity (70% ~ 80%) on the germination of Gerbera jamesonii seedlings were investigated. Explants (buds) are taken from photosynthesis
