Abstract

The pineapple belongs to the family Bromeliaceae and is a slow-growing succulent monocot with a reduced superficial root system. For this reason, the interference of weeds in competition with this crop can cause significant losses to the production. One of the bases to elaborate a control strategy is the knowledge of the diversity of weeds that occur in the cultivated areas. The objective of this study was to identify the weed community during pineapple growth in a semi-arid climate region of Brazil. Weeds were collected 60, 120, 180, 240, 300, and 360 days after planting (DAP) the pineapple. These collections were made in three different plots every two months until floral induction, composed of three pineapple cultivars. The weed community found in the irrigated pineapple field, in semi-arid climate conditions, was mostly composed by species belonging to the families Amaranthaceae, Asteraceae, Convolvulaceae, Fabaceae, Malvaceae, and Poaceae. The highest diversity of weed species was found at 60 DAP. The species Ipomoea acuminata was present throughout the development of the pineapple and showed the highest importance value index in most of the periods evaluated during the pineapple growth.

巴西半干旱地区菠萝生长过程中杂草群落的动态

菠萝属于凤梨科，是一种生长缓慢的肉质单子叶植物，浅根系减少。因此，杂草干扰这种作物的竞争可能会对生产造成重大损失。制定控制策略的基础之一是了解种植区杂草的多样性。本研究的目的是确定巴西半干旱气候地区菠萝生长过程中的杂草群落。在种植（DAP）菠萝后60、120、180、240、300和360天收集杂草。这些集合每两个月在三个不同的地块上进行一次，直到由三个菠萝品种组成的花朵诱导。在半干旱气候条件下，灌溉菠萝地中发现的杂草群落主要由苋科、菊科、旋花科、蚕豆科、锦葵科和波科的物种组成。杂草种类多样性最高的是60DAP。Ipomoea acuminata物种在菠萝的整个发育过程中都存在，并且在菠萝生长过程中评估的大多数时期都表现出最高的重要性值指数。
