Chitosan and Composition Media for Improving the Growth of Seed Sawo (Achras zapota L)

Abstract

The optimal Sapodilla plant is cultivated as a garden plant to enjoy the fruit and the fruit tree is also long-lived. The duration of the brown seed germination (generative) is the influenced by the hard nature of the seed coat so that it is difficult, to penetrate water and oxygen and cause dormancy to occur. The research aimed to determine the effect of immersion with chitosan as a growth regulator and planting media for the effectiveness of the growth sapodilla seeds. The experiment arranged factorially using Randomized Complete Design (RCD) and provided with 3 replication. The treatments consisted of 4 levels of planting media and 4 levels of chitosan concentration. The results revealed that germination of sapodilla were not influenced significantly by chitosan concentration and the media composition. Even though, there was a tendency that germination and the growth of treated seeds with 4 mLL of fitosan were relatively better than control. In addition, the media composition (1;2;1) resulted the relative better of seed growth.
