Abstract
An experimental trial was conducted to access the impact of cold stratification and different growth media on seed germination and seedling growth performance of Picrorhiza kurrooa under ex-situ conditions at lower altitude. The experiment was carried out in CRD (Completely Randomized Design) with 20 treatments, three replications and 60 seeds per treatment. Influence of growth media on seed germination was measured by thirteen parameters. Parameters such as minimum and maximum days required for initial (8.00±1.00) and final (28.67±2.08) germination was observed in T10 (Soil+Sand+Azotobacter+Cocopeat) and T18 (Soil+FYM+Cocopeat+Rockphosphate+Vermicomposte). The maximum germination percentage (83.33±8.82%), plant height (2.50±0.10) and number of shoots (3.67±0.58) were recorded in T5 (Soil+Sand+FYM+Moss). The maximum number of leaves (9.00±3.46), leaf length (1.53±0.35), leaf width (0.93±0.15), shoot length (2.70±0.26), number of roots (4.33±2.31) and root length (2.63±0.15) was found significantly superior in T18 (Soil+FYM+Cocopeat+Rockphosphate +Vermicomposte).
