Enhancing Seed Germination of Chlorophytum borivilianum Sant. Et Fernand. with PGRs, Steroidal Hormones and Zinc

R. Kaur, S. Arora and A.K. Thukral

Abstract:
The objective of the present study was to improve the seed germination of Chlorophytum borivilianum Sant. et Fernand. It is a small perennial and rare herb having aphrodisiac, antiaging, health restorative and health promotional properties. There is a great demand for this herb all over the world. In the field, the plant is grown from the tubers, making the cultivation of this plant costly and labour intensive. The plant sets a large number of seeds, which have a poor germination (8-13%) thus not being preferred by the farmers for cultivation. It, therefore, makes it imperative to understand seed germination studies to improve germination of the seeds of C. borivilianum through seed treatment with hormones or chemicals which would also otherwise add to its properties. In the present study seed treatments were given with indole butyric acid, kinetin and 24-epibrassinolide (plant growth regulators) testosterone and cholesterol (steroidal hormones) and zinc (known for vital reproductive functions in man). Characteristics of the fruits, seeds and seed viability were also evaluated. Seed germination and seedling growth of C. borivilianum were studied when given various treatments of plant growth regulators, steroids and Zinc (II). The highest germination percentage occurred with 10-6 M concentrations of testosterone (36.45%) followed by cholesterol (35.17%) with respect to control (8.5%). The maximum shoot length of seedlings was observed when seeds were treated with 10-6 M concentration of testosterone (4.43 cm), cholesterol (4.27 cm) and 24-epiBL (4.25 cm) with respect to control (2.80 cm). The maximum root length of seedling was observed in 10-6 M of cholesterol (3.83 cm) and 24-epiBL (3.65 cm) as compared to control (0.87 cm). Maximum fresh weights of seedlings were seen in seeds treated with 10-6 M concentrations of cholesterol (28.03 mg), 24-epiBL (26.21 mg) and testosterone (26.16 mg) as compared to control (10.87 mg).
