Abstract

Studies revealed that all the parameters such as germination per cent, mean germination time, germination value, germination energy, root length, shoot length and seedling vigour index were found higher in the seed extracted from yellow fruits. This identification mark may be more useful for nursery growers for production of quality seedling. Seeds were sown in different media such as top of paper, between paper, sand and top of sand. The highest vigour index was recorded on the top of sand medium. Therefore, it is suggested that sand may be as suitable medium for germination of this species under laboratory condition. Seeds of this species sown in three different positions under laboratory conditions indicated that highest vigour index (661.20) was recorded in horizontal position
