Abstract

A pot experiment was conducted to access the impact of foliar spray of triacontanol (TRIA) on the production and quality attributes of two linseed (Linum usitatissimum L.) genotypes G-20888 and G-22186 under salt stress at Government College University Faisalabad, Pakistan. Two-week-old linseed seedlings underwent exposure to two different salt stress levels: control or 0 mM NaCl and salt stress or 120 mM NaCl and TRIA was applied at different concentration (0, 10-6, and 10-7 M) as foliar spray. Plants were harvested after 90 days of growth period and gone under various growth, physiological and biochemical analysis. Statistical results showed that salt stress significantly reduced growth parameters and biochemical attributes in genotypes G-20888 and G-22186. Similarly, foliar application of TRIA at its lower concentration (10-7) substantially improved growth parameters, physiological and biochemical attributes from 10-20%, 5-10% and 4-8%, respectively, compared to plants grown in salt stress in genotype (G-20888 and G-22186). Furthermore, an analysis of variance of data for several parameters indicated that there was significant difference in the effects of both genotypes when applying varying doses of foliar-applied triacontanol (TRIA) as the genotype G-22186 has the highest values of the growth parameters, physiological and biochemical attributes while responded differently in controlled conditions as compare to salt stressed conditions.
