Germination Behaviour and Seedling Growth as Influence by Pretreatments of Seeds of Cleistanthus Collinus Benth under Storage

Archana Sharma [4] | Pradeep Vasudeva

Abstract: Cleistanthus collinus commonly known as Karra, Garari, belongs to family Euphorviaceae. In India, it occurs in many parts of Indian Peninsula. In Madhya Pradesh it is found as an associate of teak, sal and mixed forests. The wood is used for house posts. It's Fruits act as violent gastro-intestinal irritant. It's Leaves and bark used as fish poision. The tree flowers in April-May and fruits ripen in the following March-April. Natural regeneration of this species is very poor. The scarcity of natural reproduction may be attributed to the poor germination rate of the seeds. The present paper deals with the study of this species with respect to germination potential, seedling growth and biomass affected by different pretreatments with storage period. Different pretreatments were tried with fresh and stored seeds, seeds treated with hot water treatment (T2) proved to be the best treatment to stimulate seed germination as 52%, 56%, 54%, 46%, 41%, 34% and 27% in fresh and seed stored for 3, 6, 9, 12, 15 and 18 months respectively, while in control i.e. without any treatment, the germination was recorded as 20%, 24%, 18%, 14%, 10%, 4% and 0% in fresh and stored seeds for 3, 6, 9, 12, 15 and 18 months respectively. Similarly germination velocity index, seedling growth and biomass were also found to be most promising with treatment T2. The treatment T2 was found to be highly significant (P<0.05) over control and other treatments attempted.
