Abstract: An examination was directed to appraise the seedling vigour index and germination behaviour among Acacia catechu seed sources to make assessment criteria for future tree improvement programs. Ten diverse seed sources of Acacia catechu from different districts of Uttarakhand (viz. Dehradun, Rishikesh, Haridwar, Udham Singh Nagar and Nainital) and Himachal Pradesh (viz., Solan, Bilaspur, Kangra, Hamirpur, and Una) were chosen to represent generally novel regions. The newly harvested seed of the considerable number of locales was reviewed for seed vigour parameters viz., germination rate, seedling length (cm), seedling dry weight (mg), vigour index I, vigour index II and germination parameters, i.e. germination rate, germination value, germination period, and so forth were watched. The results revealed that maximum germination responses (86.66%) were recorded with Una followed by Solan and minimum in Kangra and vigour testing results revealed that maximum was recorded with Una (807.77) with paper towel method followed by Hamirpur (678.64) with minimum in Bilaspur (416) of Himachal Pradesh and Udham Singh Nagar showed best germination percent (82.76%) followed by Haridwar and minimum by Nainital of Uttrakhand. The significant variations observed among different parameters may probably be influenced by different intensities of natural constraints acting upon these traits in the prevailing geographic/climatic conditions. We conclude that distinctions in physiological properties of seed lots can be exhibited in the lab. The germination test is generally utilized for surveying the nature of seeds, yet frequently demonstrates no relationship with field emergence. Due to this inadequacy, the concept of vigour index was introduced and new tests for assessing of the strength of seed which can be utilized for additionally contemplate.
