Abstract

This study was carried out to investigate  seedlings growth performance of Annona  muricata Linn. as influenced by different light  intensities. Seedlings of A. muricata were  subjected to three (3) treatments via; growth in  direct sunlight (control), in single layered mesh  net and in double layered mesh net. Each of the  experiment was replicated three (3) times in a  Complete Randomized Design (CRD). The  variables assessed were plant height, number of  leaves, stem girth and leaf area. The data  collected were subjected to one way analysis of  variance (ANOVA). The results showed that  there were significant differences among the  treatments at 5% level of probability. Seedlings  under direct sunlight had the highest mean  height of 13.63cm, number of leaves (17.50cm),  stem girth of 1.20cm and had the least leaf area of  11.30cm2 at three month after transplantation.  This was followed by the seedlings under single  layered mesh net with mean height of 11.05cm,  number of leaves (7.00), stem girth (0.78cm) and  highest leaf area of 17.06cm2 while the least plant  height, number of leaves and stem girth was  recorded in seedlings under double layered mesh  net with mean values of 10.03cm, 5.83 and 0.68cm  respectively. It is concluded that seedlings  of Annona muricata under direct sunlight has  better growth performance than those under  single and double layered mesh net. Though, it  had the least leaf area, it recorded the highest  mean values in other parameters considered.  Therefore, direct sunlight might be required in  raising seedlings of this species.
