Parmar University of Horticulture and Forestry, Nauni, Solan, (H.P) at Herbal Garden Nauni, Shilly (Solan) and Manali (Kullu) during 2010-11 and 2011-12. Observations on morphological and quantitative characteristics of Inula racemosa were recorded from eight different sites i.e. six from Himachal Pradesh (Lahaul & Spiti) i.e. Keylong, Kardang , Dalang, Sissu, Udaipur and Kukumseri and two from Jammu & Kashmir (Kashmir valley) i.e. Tangmerg and Shopian. The results of morphological and quantitative parameters of Inula racemosa showed maximum plant height (204.90 cm), maximum leaf length (54.15 cm), maximum leaf breadth (24.85 cm), number of stems (4.74), fresh root weight (659.30 g) and essential oil content (1.96 %) from germplasm collection site G5 (Udaipur) and G6 (Kukumseri) i.e. from Pattan valley (Lahaul & Spiti) Himachal Pradesh. For seed characteristics maximum seed weight, moisture content, seed viability and germination per cent was also registered for germplasm site collection G5 (Udaipur) and G6 (Kukumseri). Among the pre-sowing treatments under laboratory and field conditions maximum germination per cent was recorded in treatment P4 (GA3 150 ppm) and minimum in control. Maximum germination energy (19.20) per cent was recorded in treatment P5 (GA3 150 ppm) and minimum in P8 (IBA 150 ppm). The maximum germination speed was recorded in treatment P6 (IBA 50 ppm) and minimum in control. The maximum mean daily germination was recorded in treatment P5 (GA3 150 ppm). The maximum germination per cent and seedling height was recorded in seeds treated with P5 (GA3 150 ppm). The maximum collar diameter (4.17 cm) and seedling vigour index (4236.0) was recorded in pre-sowing treatment P5 (150 ppm GA3). The maximum fresh shoot weight (54.10 g) and dry shoot weight (27.77 g) was recorded in treatment P5 (GA3 150 ppm). The maximum fresh root weight (9.32 g) and dry root weight (4.64 g) was recorded in seeds treated with P5 (GA3 150 ppm). The maximum root length (11.77 g) was recorded in treatment P5 (GA3 150 ppm). The effect of location site on the germination and growth of Inula racemosa at two different location sites was found to be significant. The maximum sprouting per cent, (95.35) per cent, number of shoots (4.00), number of leaves (13.73), number of flower heads (16.08) maximum primary root length (25.74 cm), fresh root weight (313.00 g) and dry root weight (148.80) was observed from germplasm collection site G5 (Udaipur, HP) and G6 (Kukumseri, HP) minimum sprouting of 80.08 per cent was obtained from germplasm collection site G8 (Tangmerg, J&K). Among the interactions maximum sprouting per cent was observed from G5×S1 (95.43 %) minimum value of 78.26 per cent was recorded in G7×S1.ensowing, germinability, vegetative propagation, developmental stages, planting, germplasm, germplasm collections, crops, biological development, biological phenomenaThesis
