- 摘要:
- 以甘蓝型油菜矮杆新品系DW871为试材，在思南、惠水、花溪区3个不同环境采用育苗移栽方法，研究了不同环境因子对DW871产量及品质的影响，以期探明DW871在贵州省内最佳生长适应区。结果表明：花溪试点平均产量最高，为3 710.20 kg?hm-2；思南试点次之，平均产量为2 417.86 kg?hm-2；惠水试点平均产量仅为2 181.09 kg?hm-2；三地平均产量2 769.72 kg?hm-2，变幅为1 529.11 kg?hm-2，表明环境对DW871产量有较大影响。环境对DW871的品质影响大，思南试点含油量（45.59%）较其余2个试点高；惠水试点含油量（45.59%）、蛋白质含量（29.26%）、亚油酸含量（14.31%）较其余2个试点高；花溪试点亚麻酸含量（6.97%）较其余2个试点高，硫甙葡萄糖苷（22.26 μmol?g-1）含量最低。相关分析结果表明，植株单株角果数和千粒质量与日照时数、降雨量显著正相关；单株产量与全生育期内有效积温极显著负相关；每角粒数和产量与日照时数、降雨量极显著正相关；芥酸、亚麻酸与降雨量、日照时数极显著正相关，硫甙葡萄糖苷、含油量与降雨量、日照时数极显著负相关。研究表明，新品系DW871在花溪试点环境下产量最高，变异系数较小，花溪试点硫甙葡萄糖苷含量最低；蛋白质、含油量、亚油酸、亚麻酸含量较高。应在海拔较高、降雨量充沛，日照时间充足、温度较低等相似于花溪环境下推广生产。
- Abstract:
- The new strain DW871 of Brassica napus dwarf stem was used as the experimental material.The seedling transplanting method was used in three different environments induding Sinan,Huishui and Huaxi,the effects of different environmental factors on the yield and quality of DW871 were studied,in order to determine the optimal ecological adaptation zone of DW871 in Guizhou Province.The results showed that the average yield of Huaxi was 3 710.20 kg?hm-2,Sinan was the second,2 417.86 kg?hm-2,Huishui was only 2 181.09 kg?hm-2.The average yield of the three places was 2 769.72 kg?hm-2,and the variation was 1 529.11 kg?hm-2,indicating that the environment had a great impact on the yield of DW871.The environment had a great influence on the quality of DW871.The content of oil content (45.59%),protein (29.26%) and linoleic acid (14.31%) in Huishui pilot was higher than the two pilots.The content of glucosinolate (22.26 μmol?g-1) in Huaxi pilot was the lowest；the content of erucic acid (1.39%) in Sinan was the lowest.Correlation analysis showed that the number of pods per plant and 1 000-grain quality per plant were significantly positively correlated with sunshine hours and rainfall；the yield per plant was extremely negatively correlated with the effective accumulated temperature during the whole growth period；the number of seeds per silique and yield were extremely significant with the sunshine hours and rainfall positive correlation.The content of glucosinolate and fat were significantly negatively correlated with rainfall and sunshine hours.Oleic acid was significantly positively correlated with monthly mean temperature and significantly negatively correlated with rainfall and sunshine hours.The results showed that the new strain DW871 was suitable to be popularized in the environment of high altitude,abundant rainfall,sufficient sunshine time and low temperature.
