Effect of Seed Source Variation on Field Emergence and Seedling Characters of Different Seed Sources of Rohida ( Tecomella undulata (Sm.) Seem)

Various morphological characters of rohida trees from four different geographical locations were recorded and seeds were collected from the selected trees. Seed quality parameters such as seed size (length and breadth), colour, test weight were recorded for all the seed sources and the seed of all represented sources were sown in the nursery to find out the field emergence, seedling survival and seedling growth parameters in different seed sources. Rajgarh seed source was found to be significantly better than other, in terms of unforkedt tree height (1.70m) and seed size (2.15cm long). Similarly seedling emergence in Rajgarh seed was 69%, which was significantly better than Churu (66.5%), Jhumpa (57%) and Dingmandi (58.2%). Seedling survival was again significantly high in Rajgarh seed source (49%) as compared to others, similar was the case of all other seedling growth characters.
