Abstract:
The present investigation entitled “ Effect of different plant growth regulators and chemicals on seed germination and seedling growth of acid lime (Citrus aurantifolia Swingle) cv. PDKV lime.” was executed in shade net of Horticultural Research cum Instructional farm under Pt. Kishori Lal Shukla College of Horticulture and Research Station, Rajnandgaon in year 2021-2022. The results revealed that seeds treated with GA₃ 90 ppm recorded minimum days required for initiation of germination (22.00), highest germination percentage (83.88%), maximum height of plant (23.23 cm), no. of leaves per plant (25.07), length of seedling (39.22 cm), root length (16.48 cm) and survival percentage (86.56%). Whereas NAA 90 ppm (T₇) was found maximum in diameter of plant stem (3.10 mm). The minimum values of the all parameters were generally manifested under Treatment T₁ (seeds were soaked in distilled water) control. Therefore it can be concluded that the T₄ (seed soaking with GA₃ at 90 ppm) was found best over rest of the treatments under study which significantly recorded desirable values of seed germination and seedling growth of acid lime.
