摘　　要：以食用辣椒为对照,研究不同遮荫度下观赏辣椒开花结果期生长发育的变化。结果表明:辣椒对遮荫有一定的适应能力,主要通过增大叶面积来实现,但长期弱光条件严重抑制辣椒的生长发育。观赏辣椒对遮荫的适应能力要强于食用辣椒;适当的遮荫能够增加观赏辣椒的分叉数,从而增加其观赏性。为了使观赏辣椒能正常开花结果,室内的照度必须保持在12 389 lx以上。Taking edible peppers as the control,the growth change of ornamental peppers in flowering and fruiting stage has been studied,in order to offer an ecological reference for ornamental pepper applying for interior design.The results showed that the adaptation to shade can be got by increasing ornamental pepper＇s leave area,but long time and low light level can seriously inhibit the growth of ornamental pepper.The shade adaptation of ornamental pepper is stronger than edible pepper;moderate shade condition can increase branches of ornamental pepper,and then make it more decorative.The light level in indoor must be kept above 12 389 lx in order to make ornamental pepper blossom and bear fruit normally.
