GROWTH ANALYSIS IN PRE-GERMINATED SEEDLINGS OF AÇAÍ (Euterpe oleracea Mart. - Arecaceae) - CULTIVATE POWERHOLE

Abstract

The açaí tree (Euterpe oleracea Mart.) is a palm tree native to the Amazon floodplains, with growing relevance in the national and international market, which has generated greater interest in its cultivation. Currently, the extractive exploitation of açaí has been partially replaced by agricultural crops on dry land, indicating the need for studies related to the species. In a sowing area of the Municipal Department of Agriculture and Rural and Economic Development (SEMADRE) of Cametá-PA, the growth analysis of the species E. oleracea (pellet) was carried out of the following parameters: stem height, radicle length, wet weight, dry weight, moisture content and absolute growth rate (ATT). Four plant collections (treatments) were carried out after the 45th day of sowing in the following periods: five (5), ten (10), fifteen (15) and twenty-five (25) days after emergence in sowing. In each period, 30 plants/treatment (time) were randomly collected, with 10 seedlings per replication. The samples were analyzed at Campus XVIII of the State University of Pará. The seedlings, without the seeds, were measured, weighed and dried in an oven at 80°C for 24 to 36 hours, until they reached constant weight. Most of the seeds showed air emergence after 30 days, in the stage called toothpick, with height ranging between 2.5 and 7.7 cm. In the first treatment (5 days), the mean values recorded were: radicle length of 5.43 cm, stem height of 5.81 cm, wet weight of 0.43 g and dry weight of 0.09 g. The TCA was 0.004 g.day⁻¹, indicating the average growth velocity. Based on the stem length, adjusted by linear regression, the ideal time to transplant the seedlings in polythene bags was estimated at 75.58 days. These results contribute to optimize the management of cultivation on dry land.
