摘要

干燥除草剂能促进早熟均匀性,提高种子的物理、生理和卫生品质。本研究的目的是评价除草剂在鹰嘴豆早期收获中的使用和对其生理品质的影响。试验设计为随机区,4个重复,考虑一个完全因子设计,一个对照(不施用)+两个因素(四种除草剂x三种不同剂量):草铵膦(200,400和500 g a.i./ha);Diquat(200、400和500克a.i./公顷);卡芬唑乙酯(15、30和37.5克a.i./公顷)和氟氟那西(49、98和122.5克a.i./公顷)。氟虫腈(49 g a.i./ha)收获预期最低(4 d),活力率最低(50.25%)。草甘膦(400 g a.i./ha)是最有希望的,它能使发芽率提高到83.75%,活力提高到78.25%,此外还能使作物的预期收获期提高17天,而在对照中观察到作物的正常周期为154天。

Chemical desiccants for anticipation of harvest and quality improvement of chickpea seeds
ABSTRACT Desiccating herbicides can promote uniformity of maturation, and early harvest and provide improvements in the physical, physiological, and sanitary seeds quality. The objective of this work was to evaluate the use of herbicides in early harvest and in the physiological quality of chickpea seeds. The experimental design was of randomized blocks with four replications, considering a complete factorial design with one control (no application) + two factors (four herbicides x three different doses): glufosinate-ammonium (200, 400 and 500 g a.i./ha); diquat (200, 400 and 500 g a.i./ha); carfentrazoneethyl (15, 30 and 37.5 g a.i./ha) and saflufenacil (49, 98 and 122.5 g a.i./ha). Saflufenacil (49 g a.i./ha) showed the lowest harvest anticipation (4 days) and a low percentage of vigor (50.25%). Glufosinate (400 g a.i./ha), was the most promising as it increased germination to 83.75% and vigor to 78.25%, in addition to promoting the anticipation of harvest by up to 17 days, while the normal cycle of the crop, observed in the control, was 154 days.
