Effect of Main Cultivation Factors on oil quality and Stability of Brassica napus Hybrids

Agricultural Science & Technology 2014年第5期15卷 795-800页

作者：赵继献杜才富任廷波程国平王仙萍贵州省油菜研究所贵州思南565109

[Objective] This study aimed to analyze the influence of five cultivation factors： sowing date, plant density, nitrogen fertilizer amount, phosphate fertilizer amount and potash fertilizer amount on oil quality and stability of Brassica napus hybrids. [Method] Statistical analysis was carried out based on the data from previous studies and our work. [Result] Sowing date had no significant influence on oil quality and stability of B. napus hybrids. The plant density shared a positive correlation with 18-C fatty acid （FA） content, unsaturated fatty acid （UFA） content, total content of linoleic acid and linolenic acid, index of unsaturated fatty acid （IUFA）, so a large plant density can improve the oil quality （by increasing18-C FA content, UFA content, total content of linoleic acid and linolenic acid）, but reduce the oil stability （by increasing IUFA）. The amount of nitrogen fertilizer had no significant influence on the contents of 18-C FA and UFA, but significant positive correlations with the total content of linoleic acid and linolenic acid and IUFA. So, the total content of linoleic acid and linolenic acid can be reduced by increasing nitrogen amount, meanwhile the oil stability was also decreased. Phosphate fertilizer amount did not affect 18-C FA significantly, but was negatively correlated with the UFA content, total content of linoleic acid and linolenic acid, and IUFA. So, increasing the amount of applied phosphate fertilizer can reduce UFA content, total content of linoleic acid and linolenic acid, thereby improving oil stability. Potash fertilizer had no significant influence on the IUFA, a significant positive correlation with 18-C FA content, an insignificant positive correlation with the the UFA content, and a negative correlation with the total content of linoleic acid and linolenic acid. The oil content of rapeseed shared an extremely significant positive correlation with 18-C FA content and UFA content, an negative correlation with the total conten

Seed Priming Influence on Early Crop Growth, Phenological Development and Yield Performance of Linola (Linum usitatissimum L.)

引用

Journal of Integrative Agriculture 2014年第5期13卷 990-996页

作者： Hafeez ur Rehman Muhammad Qaiser Nawaz Shahzad Maqsood Ahmed Basra Irfan Afzal Azra Yasmeen Fayyaz ul-Hassan Seed Physiology Laboratory Department of Crop Physiology University of Agriculture Faisalabad Soil Salinity Research Institute Pindi Bhatian College of Agriculture Bahuddin Zakriya University Department of Agronomy PMAS University of Arid Agriculture

Reduced early crop growth and limited branching are amongst yield limiting factors of linola. Field response of seed priming treatments viz. 50 mmol L^-1 salicylic acid （SA）, 2.2% CaCl2 and 3.3% moringa leaf extract （MLE） including untreated dry and hydropriming controls was evaluated on early crop growth and yield performance of linola. Osmopriming with CaCl2 reduced emergence time and produced the highest seedling fresh and dry weights including Chl. a contents. Osmopriming with CaCl2 reduced crop branching and flowering and maturity times and had the maximum plant height, number of branches, tillers, pods and seeds per pod followed by MLE. Increase in seed weight, biological and seed yields was 9.30, 34.16 and 39.49%, harvest index （4.12%） and oil contents （13.39%） for CaCl2 osmopriming. Positive relationship between emergence and seedling vigor traits, 100-seed weight, seed yield with maturity time, 100-seed weight and seed yield were found. The study concludes that seed osmopriming with CaC12 or MLE can play significant role to improve early crop growth and seed yields of linola.

This article deals with the biochemical characteristics of varieties of Saint Mary’s Thistle such as Panacea, Debut and Samaryanka. Based on the studies, it was found that the highest oil content was found in the species Debut (26%). The lowest oil content was observed in the variety Samaryanka (19%). The highest protein content and the sum of total amino acids in the seeds of St. Mary’s Thistle varieties were found in the variety Debut (131.1), and the lowest indication was observed in the species Samaryanka (79.2). By the number of replaceable amino acids existing in the seeds of the species of St. Mary’s Thistle, it was found in the Varieties Debut (126.3), and the lowest indication was observed in the variety Samaryanka (112). Based on the results of studies and the noted biochemical characteristics and varietal differences of the St. Mary’s Thistle, the possibility and expediency of expanding the crops of this species in the soil and climatic conditions of the Khorezm region are suggested. The research was conducted 2017-2019 y.

荠菜(Capsella bursa-pastoris,2n=32)为天然的“双低”种质资源并对菌核病(Sclerotinia sclerotiorum)有较高的抗性。我们进行了甘蓝型和白菜型油菜(***,2n=38;***,2n=20)与荠菜的族间有性杂交,以改良油菜的品质和菌核病抗性。甘蓝型油菜×荠菜的F1植株中,除了三株单倍体(2n=19)和几株2n=29的外,其它植株的染色体数目和母本甘蓝型油菜相同。只有少数几株F1单株表型为中间型,其他单株尽管表型各异,但和母本很相似。在F1中,我们发现3株表现荠菜白花的植株,两株(2n=38)来自甘蓝型油菜×荠菜组合,一株(2n=279)来自白菜×荠菜组合。GISH分析表明,少数几株F1的花粉母细胞中有1条荠菜染色体,大多F1的子房细胞和花粉母细胞中有荠菜的染色体片段渗入。AFLP分析表明,大多F1植株含有父本的带,甚至在单倍体植株中也有。通过脂肪酸分析和菌核病鉴定,我们发现一些后代具有很好的品质和较抗菌核病的特性。本文讨论了外源遗传物质渗入的机制,以及族间杂交对油菜改良的意义。
