不同微型鲜食胡萝卜品系生长特性与营养品质比较

Comparison of Growth Characteristics and Nutritional Quality of Different Miniature Fresh-eating Carrot Varieties

为了丰富鲜食胡萝卜市场,筛选较适宜的微型鲜食胡萝卜品种。本试验比较了引进6个微型鲜食胡萝卜材料的生长周期、外观品质和营养品质,筛选适宜山西省栽培的鲜食品种。结果表明:6个鲜食胡萝卜材料的生长期均为95~101 d,生长周期长的品系其肉质根膨大期也长;品系‘B924’‘B966’和‘B913’根长较长,根型较细,中柱粗占根粗的比例最小;只有品系‘P1129’的根型属于长圆锥形,其余5个品系均是细长型;且6个胡萝卜材料生长较为整齐一致;营养品质方面,6个品系的含水量为87%~91%,品系‘P1129’的VC含量和可溶性糖含量最高,品系‘B913’和‘B924’的蛋白质含量最高。综合来看‘B966’‘P1129’和‘B924’较适宜山西省的栽培环境,可发展为当地的鲜食品种。

In order to increase fresh-eating carrot types in the market,screening suitable miniature fresh-eating carrot varieties.Six fresh-eating miniature carrot varieties were introduced in the experiment,and their growth cycle,appearance quality and nutritional quality were compared so as to select suitable varieties to grow in Shanxi Province.The results showed that the growth cycle of each variety was 95-101 d,and the variety with long growth period also had long fleshy root expansion period.‘B924’‘B966’and‘B913’had longer root length and finer root shape,and the proportion of the middle column diameter to the whole root diameter was the smallest.Only‘P1129’had a long conical root type,while the other five varieties were all slender type.The growth of the six carrot materials was relatively uniform in the local area.In terms of nutritional quality,the water content of 6 fresh eating carrot materials was 87%-91%,‘P1129’had the highest content of VC and soluble sugar,and‘B913’and‘B924’had the highest content of protein.In total,‘B966’‘P1129’and‘B924’are more suitable for cultivation in Shanxi Province and can be developed into suitable local fresh food carrot varieties.
