摘  要:
运用梯度变化光照对新铁炮百合开花进行了研究。结果表明:新铁炮百合为绝对长日照植物,其光周期临界暗期约为11.5 h。对长于12.5 h的光照长度而言,新铁炮百合花蕾长度的增长率随日照长度的延长呈S型曲线,曲线转折点为14.5 h的光照长度。

摘  要:
Using gradient illumination time,the flowering of Lilium formolongi was studied.The results showed that Lilium formolongi belonged among the absolute long-day plant,and its critical dark period was about 11.5 h.The growth rate of bud length showed "S" curve with illumination time passing for the illumination time which were longer than 12.5 h.Moreover,the corresponding illumination time of "S" curve turning point was 14.5 h.
