摘要

在大豆生产中,由于病害的发展和田间控制方法的不同,通常会影响收获的籽粒品质。本研究旨在评价印楝种子提取物(AENS)在田间防治亚洲锈病条件下对作物处理后大豆籽粒健康的影响。试验在喀麦隆第五农业生态区的米梅塔和恩科梅托进行。以“Locale”、TGX 1835-10E和TGX1910-14E 3个大豆品种为试验材料,采用完全随机区组设计,共设5个处理:T0(对照)、T1、T2、T3(分别添加25、50、100 g/L提取物)和T4(添加5.33 g/L大车前碱80wp)。在收获的谷物上发现了这种疾病;通过对其含量的提取和测定,评价了其在这些谷物中的发病率和一些生化参数。许多谷物受到亚洲铁锈的侵袭。与T1、T2、T3处理的种子相比,未经处理的种子发病率最高(35%)(1.14;分别为1.07和0.95%)。与T0和T4处理相比,不同剂量的AENS处理提高了收获籽粒中所有生化化合物的含量。TGX1910-14E品种含量最高。T3期,籽粒生化化合物含量为415.17;118.83;118.33;44.43;总蛋白、球蛋白、白蛋白、谷蛋白、蛋白胨和葡萄糖的干物质含量分别为36.53和10.83 mg/g。T4处理,籽粒含量为403.49;112.95;112.78;40.58;分别为33.90和9.91 mg/g。本研究表明,在大田条件下施用印楝种子提取物防治亚洲锈病,最大剂量(如100 g/L)可改善收获的籽粒品质。楝树提取物作为一种天然物质,可用于大豆和其他作物病虫害的综合治理。

Qualities of Soybean Grains Harvested on Crops Treated with Neem Seeds Extract in Field Conditions against Asian Rust
In soybean production, qualities of grains harvested are usually affected according to the development of diseases and control methods used in the field. This study aims to evaluate the impact of neem seeds extract (AENS) on soybean grains health after crops treatment in field conditions for the control against Asian rust. Experiment was conducted in Mimetala and Nkometou, located in the agroecological zone V of Cameroun. Three varieties of soybean (“Locale”, TGX 1835-10E and TGX1910-14E) were used in a completely randomized blocks design containing five treatments: T0 (control), T1, T2, T3 (25, 50, 100 g/L of extract respectively) and T4 (5.33 g/L of Plantineb 80wp). The disease was identified on the harvested grains; its incidence on those grains was evaluated and some biochemical parameters were assessed by extraction and determination of their contents. Many grains were attacked by Asian rust. The highest incidence was obtained in the seeds from untreated plots (35 %), compared to those from T1, T2, T3 (1.14; 1.07 and 0.95 % respectively). The different doses of AENS improved the content of all biochemical compounds tested in harvested grains compared with the T0 and T4 treatments. TGX1910-14E variety presented the highest content. In T3,grain contents in biochemical compounds were 415.17; 118.83; 118.33; 44.43; 36.53 and 10.83 mg/g of dry matter from total proteins, globulin, albumin, Glutelin, prolamin and glucide respectively. Meanwhile, in T4 treatments, grain contents were 403.49; 112.95; 112.78; 40.58; 33.90 and 9.91 mg/g of dry matter from the same compounds respectively. This study shows that the application of neem seeds extract on soybean crops for the control of Asian rust in field conditions at the maximum dose (e.g. 100 g/L) can improve the qualities of harvested grains. The neem extract as a natural substance should be used in integrated pest management of soybean and other crops.
