摘　　要：以棉花为材料研究了硫灯和氙灯照射对其生长发育的影响。结果显示:用硫灯代替氙灯能通过抑制棉花幼苗胚轴的表皮和皮层细胞伸长而控制胚轴徒长;增加棉花分枝数、花蕾数和棉桃数。实验结果表明:应用硫灯照射更有利于棉花植株的形态建成及产量的形成。Experiments were carried out with cotton (Gossgpium hirsutum cv.Xuzhou 142) plants to study the effects of illumination with xenon and sulfur lamp on development of cotton plants. The results showed that, compared with xenon lamp, illumination with sulfur lamp inhibited excessive elongation of hypocotyl via promotion of lognitudinal elongation of epidermis and cortex cells (Table 1), increased the numbers of branches, buds and bolls significantly (Table 2, Fig.2). It suggested that illumination with sulfur lamp rendered cotton photomorpho-genesis more favorable to yield formation.
