48份红花材料种子含油率及其籽油脂肪酸分析

Analysis of the oil and its fatty acids percentage of the seed of 48 safflower accessions

对川红一号、简阳红花以及来自32个国家的共48份红花材料种子含油率及其籽油脂肪酸组成及含量进行测定,并开展了红花主要农艺性状与种子含油率、籽油中各脂肪酸含量间相关分析。结果表明,来自加拿大的PI559909和法国的PI253529的种子含油率最高,分别达32.68%和31.60%。来自加拿大的PI559909和奥地利的PI253518亚油酸含量最高,分别为83.79%和81.67%。孟加拉国的PI401479油酸含量最高,达53.10%。综合单株种子产量、种子含油率和亚油酸、油酸含量等几个重要指标,发现以加拿大PI559909和匈牙利的PI312275表现较好。试验结果还表明,种子含油率与株高呈极显著负相关和负偏相关,与花期呈显著负相关,与棕榈酸含量呈显著负偏相关。油酸的含量与株高呈显著负相关和负偏相关。亚油酸含量与油酸含量呈极显著负相关,而亚油酸含量与棕榈酸含量呈极显著正相关。棕榈酸含量分别与亚油酸含量和油酸含量呈极显著正偏相关,油酸含量则与亚油酸含量呈极显著负偏相关。

Oil and its fatty acids percentage of the seeds of 48 safflower accessions, including Chuanhongl ,Jianyanghonghua and some other safflower accessions from 32 countries were measured, The correlation relationship between the oil percentage and different agronomy characters, between the fatty acids percentage and different agronomy characters, between the oil percentage and different fatty acids percentage were analyzed. The results in- dicated that PI559909 from Canada and PI253529 from France were excellent at oil percentage,with the percentage of 32.68 % and 31.60 % respectively. P1559909 from Canada and P1253518 from Austria had the highest linoleic acid percentage,which reached 83.79 % and 81.67 % ,respectively. P1401479 from Bengal had the highest oleic acid percentage （53.10 % ）. Considering seeds yield per plant, oil percentage, linoleic acid percentage and oleic acid percentage, PI559909 from Canada and P1312275 from Hungarian were the excellent. The results also showed the negative simple and partial correlation coefficient between plant height and oil percentage was significant at 0.01 level, significant at 0.05 level between blooming time and oil percentage, significant at 0.05 level between palm acid percentage and oil percentage. The negative simple and partial correlation coefficient was significant at 0.05 level between oleic acid percentage and plant height. The negative simple and partial correlation coefficient was significant at 0.01 level between linoleic acid and oleic acid percentage. The positive simple and partial correlation coefficient was significant at 0. 01 level between linoleic acid and palm acid percent. The positive partial correlation coefficient was significant at 0.05 level between oleic acid and palm acid percentage.
