Abstract

The objective of this research was to evaluate the population dynamics of the nematodes Heterodera glycines race 5 and Pratylenchus brachyurus in a succession crop of soybeans and chickpeas. The experiment was carried out in Campos Novos dos Parecis, MT State, Brazil, from February to May 2017. Six chickpea cultivars were planted in February and evaluated in a naturally infested area of 60 ha. Five soil samples were collected at random in georeferenced and equidistant locations, forming a composite sample by replication. Five plants per georeferenced point and new soil samples were collected at regular intervals of about 30 d. The nematodes were extracted, identified, and counted. Data were subjected to variance and regression analyses. A reduction in the population levels of H. glycines race 5 was observed throughout the chickpea cycle, indicating that this species can be cultivated in succession with soybeans in the presence of this nematode. However, due to the maintenance in the population of P. brachyurus in the roots, rotation of soybean with chickpeas is not recommended in fields naturally infested with this nematode.

大豆和鹰嘴豆继代作物中大豆异狄氏线虫和短吻Pratylenchus brachyurus的种群动态

本研究旨在评价大豆和鹰嘴豆演替作物中甘氨酸异线虫5小种和短柄柄线虫的种群动态。该实验于2017年2月至5月在巴西MT州Campos Novos dos parrecis进行。在2月份种植了6个鹰嘴豆品种，并在60公顷的自然侵染面积上进行了评价。在地理参考和等距位置随机收集5个土壤样品，通过复制形成复合样品。每个地理参考点采集5株植物，每隔30 d定期采集新的土壤样品。提取、鉴定和计数线虫。数据进行方差和回归分析。在整个鹰嘴豆生长周期中，观察到甘氨酸H. 5小种的种群水平下降，表明该品种可以在该线虫存在的情况下与大豆一起连续栽培。然而，由于短叶线虫在根部的种群维持，在该线虫自然侵染的田地，不建议将大豆与鹰嘴豆轮作。
