INTRODUCTION A seed is a fertilized ovule that contains an embryo and transforms it into a new plant through the process of germination. Seeds remain inactive until conditions are right for germination. All seeds need water‚ oxygen‚ and proper temperature in order to germinate. However‚ some seeds require full light or darkness to germinate. According to Holm (1996) seeds have chemical inhibitors that prevent germination. A seed will not grow unless those inhibitors are destroyed by things like
