【摘要】 采用梯度法比较了温度、光照度、光照周期对一次性培养的塔胞藻生长的影响。结果表明:塔胞藻对温度的适应范围较广,10~30℃时塔胞藻均可生长,24~28℃为塔胞藻生长的最适温度;光照度4000~10 000 lx时,塔胞藻生物量随光照度的增加而增大,并在10 000 lx时达到最大;塔胞藻在光照周期为16L∶8D时生长最快。更多还原

【Abstract】 The effects of three ecological factors including temperacture,illumination indensity and photoperiod on growth of Pyramimonas sp.culture were studied.The results indicated that the growth condition of the alga conformed to a wide temperature rang(10～30 ℃) with the optimal temperature of 24～28 ℃.The biomass of the alga increased with the increasing illumination indensity(4000～10 000 lx),and reached the peak when illumination indensity was at 10000 lx.The alga had the maximal growth at the photoperiod of 16L∶8D.更多还原
