| Abstract | Plant extracts can enhance and promote plant growth by a wide variety of mechanisms. Some of these aqueous plant extracts were screened in vitro for their plant growth promoting trait such as the production of amylase, ammonia, acetoin and indole acetic acid (IAA). All the aqueous tests produced amylase, ammonia and IAA, whereas the production of acetoin was only possible with 10% papaya pericarp plus effective microorganisms (EM), and with 10% papaya pericarp in EM with chitosan: 200, 400 and 600 ppm. Many treatments showed two times efficiency, much better than the control treatment at 192 h for chilli seedlings. Treatments with EM 1% extract and 1% papaya leaf + pineapple leaf in EM with chitosan 600 ppm presented the highest chilli seed germination index vigor for seedlings at 137% and 1056, respectively. |
