【摘要】 在农用塑料薄膜搭制的旱棚内,严格控制供水量,依耐早系数为依据,对陕西省110份来自不同生态区的谷子品种资源的耐旱性进行鉴定,从中筛选出25个耐旱材料,列出了谷子在水分胁迫下其生态性状的耐旱性变差序列:千粒重>主茎节数>穗粗>株高>穗茎长>穗长>主茎直径>单株杆重>单株穗重>单株粒重。更多还原

【Abstract】 Water supply is rigidly controlled in the drought-shed covered with agricultural plasticsheet.According to the basic drought-resistance coefficient,110 millet varieties from differ-ent resources in different ecological regions in Shaanxi Province were identified.Of which 25drought-resistant varieties were screened.The sequences of variations in drought resistanceof ecological characteristics of millet were listed.They are as follows:1000 grain weight>nodes of stalk>roughness of spike>height of plant>length of spike stalk>length of spike>diameter of stalk>weight of stem/plant>weight of spike/plant>weight of kernal/plant.更多还原
