摘　　要：利用4个笋子芥主栽品种,种植于海拔高度相差约500 m的4个川西高山地区(1510~2936 m),分别调查株高、开展度、食用茎长度等8个主要农艺性状,探究海拔变化对笋子芥主要农艺性状的影响。结果表明:随海拔升高,笋子芥株高、食用茎长和食用茎节间长度总体上呈降低的趋势,食用茎粗和食用茎皮厚总体上呈增加的趋势,开展度总体上呈先增大后减小的趋势;单株毛质量、单株净质量、食用茎粗和食用茎皮厚之间均呈正相关,且均与株高、食用茎长和食用茎节间长度呈负相关,其中4个笋子芥品种的食用茎粗与食用茎皮厚均呈显著正相关。Four primary varieties of tuber mustard were employed and planted in four high-altitude mountainous regions in western Sichuan,ranging from 1510 to 2936 m above sea level,with altitude differences of 500 m between them.In each of these regions,we investigated eight key agronomic traits,including plant height,plant spread,edible stem length,and so on,to explore the impact of altitude variation on the key agronomic traits of tuber mustard.The results showed that as the elevation increased,the plant height,edible stem length,and edible stem internode length exhibited trend of decreasing,the edible stem diameter and skin thickness appeared trend of increasing,the plant spread showed trend of increasing and then decreasing.Furthermore,positive correlation was observed among the gross weight per plant,net weight per plant,edible stem diameter,and edible stem skin thickness,and these traits were inversely correlated with the plant height,edible stem length,and edible stem internode length.Notably,strong significant correlation emerged between edible stem diameter and edible stem skin thickness across all four tuber mustard varieties.
