Influence of Palm Oil Nuts Thickness (elaeisguineensis jacq.) on Germination and Growth of Seedlings in Nursery
Installation program of palm plantations with a hybrid of short size, early vegetable material and of good productivity arouse a keen interest with the growers. The objective of the present study is to observe three categories of palm tree seeds to see the impact of their size on germination as well as growth of the seedlings in pre-seedbed. The test was carried out on Palm tree seeds left again in 3 batches of 130 seeds of which larges (of diameter > 2,5 cm), the averages (variable diameter between 1,5 with 2,5 cm), and the small seeds (diameter <1,5 cm) by using the method of germination by dry heat or DRY HEAPEDTRAITED (DHT). For the crossing (a), the small seeds had a rate of germination higher compared to seeds of average size or large seeds. The rate of germination was respectively 66,1%;16,2 % and 12,3 %. This tendency was the same for the crossing (b). For this latter, the rate of germination was respectively 84,6; 66,1 and 57,7 %. In term of performance treatment 1 came at the head with a diameter to the collet 27,31 cm, followed from 4 with 24,32 cm; 5 with 23,30 cm; 2 with 23,28 cm and 3 and finally treatment 6 per 23,14 and 17,90 cm respectively. Thus, we concluded that seeds age influence germination and the growth of the seedlings. Télécharger l'article
