Physiological as Well as Growth Parameters of Basmati Rice (Oryza sativa L.) as Affected by Growth Regulators

摘要

Plant Growth regulators (PGRs) are known to improve physiological efficiency including the photosynthetic ability of plants and offer a significant role in realizing higher crop yields. It affects the physiological characters such as plant height, number of effective tillers per plant, number of leaves per plant, RWC, Chlorophyll Intensity and growth parameters such as CGR, RGR, and NAR of Basmati rice. The plants were foliar sprayed with PGRs (IAA, Kinetin, CCC, SADH and Ascorbic Acid) at tillering and before anthesis stage. Results showed a conspicuous increase in growth traits in treated plants. All the traits described above were significantly improved by the treatment of IAA.
