摘要
对５８个南美藜品种（系）在西藏林芝地区的生物学特性进行了系统观察，根据生育期及对水分的需求，将试材分成３大类型：Ⅰ．早熟干旱型，Ⅱ．中熟灌溉型，Ⅲ．晚熟河谷型。所有参试材料在西藏都能正常开花结实，但中、晚熟材料在西藏不同海拔地区分枝习性差异较大；大部分试材冻害萎蔫起点温度≤－５．５℃，致死起点温度≤－９．０℃。
quinoa varities from fived different contries of South America40°S～2°N,sea level to 4000melevation),Planted in the Tibetan Nyingchi regio,Depend on the growth duration and droughtresistance,there are three different types of quinoa..Early maturity and drought resistance ,Ⅱ.Mid-maturity and irrigated;Ⅲ.Late maturity valley type.Whole growth duration separated into:1)Germination duration;2 )Seedling duration ;3)Inflorescence duration ;4 ) Anthesis duratio;5)Milking duration. All materails anthesis and fruited in Tibet.We studied biological charateristics ofQuinoa in Tibet, incloding roots、stems、leaves、flowers、fruits and resistance to frost、drought. Formost materials,frost wilting temperatures are≤-5.5℃, death temperatures≤-9.0℃.
