GERMINAÇÃO DE SEMENTES DE NIM (AZADIRACHTA INDICA A. JUSS) EM FUNÇÃO DO TIPO DE COLETA E DA COLORAÇÃO DOS FRUTOS

Abstract

The neem tree is a species belonging to the family Meliaceae, whose seed, under normal conditions, have low longevity. This study aimed to evaluate the germination of seeds of neem depending on the type of collection of its fruits, if the ground or in the tree and depending on the colour. The treatments were: T1-giving tree in green tint, T2-giving flesh on the floor; T3-on the floor with remnants of flesh; T4-the tree of yellow; T5-the tree in different colours. The moisture content fruit and seeds were determinate. The germinated test in germinator the alternating temperature of 20-30ºC was conducted. It was used four replicates of twenty seeds per treatment, except for treatment of yellow that owned four replicates of fifteen seed. The characteristics were evaluated percentage and speed of emergence index (IVE) and percentage of normal seedlings. The results showed that the seeds of the neem fruits collected from the ground, that were partially with pulp, showed greater physiological quality.
