摘要：This study explores the potent ial of Moringa oleifera leaf extract (MLE) in seed germination and growth of seedlings of P araserianthes falcataria . Seed priming was done by soaking the seeds in hot water for 1 minute and in different dilutions of the MLE extracts in distilled water (MLE 1:10, MLE 1:20, MLE 1:30, MLE 1:40, MLE 1:50) for 24 hours. In the application of foliar fertilizer, MLE was prepared by dilutions with distilled water (MLE 1:1, MLE 1:3, MLE 1:5) applied to a 3 - day old P. f alcataria germinants and evaluated after 45 days . The experimental set up was laid - out in a complete randomized design with 30 experimental samples replicated 3 times. In the seed germination test, hot water treatment and seed priming treatment with dilutions of MLE 1:40 and ANAA (commercial growth horm one) were more effective methods to improve final germination percentage (FGP) to synchronize early germination. All seed priming treatments (MLE 1:10, MLE 1:20, MLE 1:30, MLE 1:40, MLE 1:50 and ANAA) and hot water treatment of P. falcataria seeds were mor e effective compared with control in all parameters except for time until 50% germination (T50) and germination energy period (GEP) . Treatments MLE 1:40, hot water and ANAA were among the most efficient treatments that would improve the germination attribu tes of P. falcataria seeds. The application of M LE , commercial foliar fertilizer (Grow More) and control have the same effect on the growth vigor of P. falcataria seedlings as exhibited by the root collar diameter, height, root - shoot ratio, fresh shoot wei ght, oven - dry shoot weight, total fresh weight, total oven - dry weight and moisture content. However, it reveals that root nodule count and fresh root weight were significantly different from the control ( p < 0.05) but the oven - dry root weight was found to be not significantly different from the control ( p > 0.05). The MLE possess potential as seed priming treatment but as an organic fertilizer more in - depth study is needed
