兰州食用百合不同种植区干物质累积和粗淀粉、粗蛋白含量分析

【目的】 研究兰州食用百合不同种植区干物质累积和粗淀粉、粗蛋白含量变化规律,分析地域差异。【方法】 采用生长分析方法,检测百合鳞茎干物质累积和粗淀粉、粗蛋白含量变化特征。【结果】 不同生长年限永靖县、渭源县、临洮县种植区兰州食用百合鳞茎干物质累积增长幅度不同,3个种植区相比较,百合鳞茎干物质累积量差异均达极显著水平(P＜0.01)。3年生兰州食用百合鳞茎干物质累积量大小为临洮县＞渭源县＞永靖县。百合鳞茎粗淀粉含量临洮县高于永靖县(24.74%)和渭源县(68.02%),粗淀粉含量高低顺序为:临洮县＞永靖县＞渭源县;百合鳞茎粗蛋白含量临洮县高于永靖县(8.55%)和渭源县(11.09%),粗蛋白含量高低顺序为临洮县＞永靖县＞渭源县。3年生兰州食用百合,渭源县和临洮县种植区鳞茎干物质累积量与粗蛋白含量均呈极显著正相关(0.99^**,1.00^**,P＜0.01)。【结论】 不同种植区兰州食用百合营养物质含量不同,区域间差异显著。

Study on the Change of Dry Matter Accumulation and the Contents of Crude Starch and Crude Protein in Lanzhou Edible Lily in Different Planting Areas

【Objective】 To study the changes of dry matter accumulation and crude starch and crude protein content in edible lily of Lanzhou in different ecological regions and to explore the regional differences. 【Method】 The growth analysis method was used to detect the accumulation of dry matter and the changes of crude starch and crude protein content in lily bulbs.【Results】 The cumulative growth of dry matter of lily bulbs in different growth years of Yongjing County (YJ), Weiyuan County (WY) and Lintao County ( LT) planting areas was different. Compared with the three planting areas, the differences in dry matter accumulation of lily bulbs reached extremely significant levels (P<0.01). The cumulative amount of dry matter of Lanzhou edible lily bulbs in triennial was: LT>WY>YJ. The crude starch content LT of lily bulb was higher than those of YJ (24.74%) and WY (68.02%). The order of crude starch content was: LT>YJ>WY; the crude protein content LT of lily bulb was higher than those of YJ (8.55%) and WY (11.09%), the order of crude protein content was: LT>YJ>WY. The triennial Lanzhou edible lily, the dry matter accumulation of the WY and LT eco-regions was significantly positively correlated with the crude protein content (0.99^**, 1.00^**, P<0.01).【Conclusion】 The nutrient content of edible lily in different planting areas was different, and the difference between areas was significant.
