Levels of abscisic acid were followed in the xylem sap, mature leaves, and apices of field-grown willow (Salix viminalis L.) during the summer months, under natural and artificially extended photoperiods. Although the long day treatment prevented the general onset of dormancy, the plants grown under natural daylengths showed lower concentration of abscisic acid than those kept under long days.
在夏季,通过自然和人工延长光照周期的方式,监测野外生长的柳树(Salix viminalis L.)的木质部汁液、成熟叶片和顶芽中的脱落酸水平。尽管长日照处理阻止了休眠的普遍发生,但在自然日照条件下生长的植物的脱落酸浓度低于在长日照条件下生长的植物。
