Abstract:

Plants are significantly affected by the ambient temperature for regulating their growth and development. Salvia sclarea L. is a temperature sensitive plant and prefers a temperate climate and habituate naturally above 2,000 meters above sea level, but it has been introduced successfully in sub-tropical plains as a winter season crop. Seed germination in sub- tropical climatic conditions varied under different temperature. Using laboratory incubation technique, a research investigation was carried out at CSIR-Central Institute of Medicinal and Aromatic Plants, Lucknow, Uttar Pradesh, India, to analyzed and assessed seed germination and emergence in relation to temperature variability. The impact of variability in temperature on germination of seeds and emergence was monitored daily at constant temperatures that ranged from 5 ⁰C to 30 ⁰C with 5 ⁰C increments. Results of the study indicated that temperature had a considerable impact on germination of and emergence of Salvia sclarea L. The maximum seed germination (78.50%) was found at 25 ⁰C, followed by 20 ⁰C (74.44%), and 15 ⁰C (65.80%) while lowest at 5 ⁰C (2.33%). Similarly, first seed emergence was occurred at four days at 25 ⁰C. Therefore, it was proclaimed that suitable temperature needed for seed germination of Salvia sclarea L. is varied between maximum 25 ⁰C to minimum 15⁰C for maximum germination and early emergence.
