EFFECT OF SEED STORAGE ON GERMINATION AND SEED VIGOUR OF TECOMELLA UNDULATANishita, Vishal Johar, Vikram Singh, Siriki Gopinath and Moses Malsawmsanga ColneyAbstract The present study was carried out at the forestry research area of Lovely Professional University, Phagwara (Punjab) to evaluate the optimum temperature for seed germination and seed vigour of Tecomella undulata. Seeds from 150 candidate plus trees (CTPs) were placed at three different substrata, i.e. top of paper, between the paper and sand at different temperature viz. 20 oC, 25 oC and 30 oC, respectively in a seed germinator and the data for the optimum temperature for seed germination was recorded after 10 days. The data pertaining to standard germination, root length, shoot length, seedling dry weight, seedling vigour index- I and seedling vigour index-II were recorded to evaluate the performance of the fresh Rohida seeds. Results revealed that during storage, there was a loss of viability in the seeds. However, non-significant decrease was observed in seedling length and seedling dry weight after six months of storage. Therefore, the findings of the present study reveal that six months after storage, quality planting stock can be produced by increasing the seed rate. |
