The Effect of Seed Maturity on Germination and Subsequent Seedling Growth of Pongamia pinnata (L.)

Pongamia pinnata or commonly known as Pongam is an economically tree especially as biodiesel, ornamental tree and medical uses. This species has been planted widely because it potentially as to produce biodiesel. Due to its ability as many important functions to human being, many studies were conducted to determine its maturity and germination performance. There are three treatments involve in this study which is three different type of seed maturity: green seed (M1), greenish-brown seed (M2) and brown seed (M3) and also three pretreatments for each different type of seed maturity which is Indol-3-Butyric Acid (IBA) and Gibberellic Acid (GA3) and control where seeds were soaked without any treatment. The potting media such sand was used to plant all the selected seeds after the seeds were soaked in different growth regulators. The potting media such topsoil and coco peat was mixed to plant the selected seed for growth study. The germination of the seedlings was observed for their length of leaf, width of leaf, height of seedling, stem diameter of seedling and number of leaf. Seeds are treated with GA3 in M1 showed better germination percent compared to control and IBA pretreatment. M3 showed better result in height of seedling, number of leaf, stem diameter of seedling and total leaf area
