Analysis on ecological properties and ornamental effect of 10 Iris species at subtropical areas in China demon- strated that Iris could be pided into two functional types: winter & spring, summer.
分析研究了适合亚热带地区的10种鸢尾属观赏地被植物的生态特性与景观效果,结果表明,在中国亚热带地区,鸢尾属种类可划分为冬春功能群和夏季功能群两大类,其中鸢尾、蝴蝶花和德国鸢尾适合春季观赏,其余种类适合在春夏观赏;在春季,溪荪的光合速率最高,德国鸢尾和黄菖蒲次之,蓝蝴蝶花和白蝴蝶花最低;蒸腾速率的顺序也为溪荪最高,蓝蝴蝶花和白蝴蝶花最低;德国鸢尾由于相对较高的光合速率和相对较低的蒸腾速率,水分利用效率最高,花菖蒲则因相对较高的蒸腾速率和相对较低的光合速率,水分利用效率最低。
