摘　　要：试验于１９８６年，在广州（２３°０８＇Ｎ，海拔８．８ｍ）华南农业大学农场自然条件下进行，主要结果如下：１．稻属植物２０个种的光周期反应，可分为：钝感型、敏感型和极敏感型。亚洲稻（栽培种“白壳金风”）和非洲稻属于敏感型。２．依光周期反应、谷粒长、谷粒长／宽和护颖长度，稻属２０个种可分成４个系，即栽培稻系（ｓｅｒｉｅｓｓａｔｉｖａｅ）、小粒野稻系（ｓｅｒｉｅｓｍｉｎｕｔａｅ）、长粒野稻系（ｓｅｒｉｅｓｌｏｎｇｉｇｒａｎａ）和长护颖野稻系（ｓｅｒｉｅｓｌｏｎｇｉｇｌｕｍｉｓ）。This experiment was conducted at the South China Agricultural University farm undernatural conditions of Guangzhou(23°08'N,an elevation of 8.8 metres),in 1986.The main resluts are as follows: 1. The photoperiodic reaction of 20 species tested maybe divided into:insensitive type, sensitive type and extremely sensitive type.O. sativa(cultivar “Bai─ke─jin─feng”)and O. glaberrima are sensitive type.2.Based on thephotoperiodic reaction,grain length,length/width of grain and empty glume length,twenty species of Oryza tested may be classified into four series:
