how salicylic acid modulate photosynthetic pigments, yield and yield components of canola plant

چکیده

in this experiment, the possibility of growth promoting of exogenous salicylic acid during two growth stags on chlorophyll content, yield and yield components of canola plant was investigated. for the purpose of improving above traits, salicylic acid was applied in four concentrations (0, 100, 200 and 400 µm) during two different growing stages (first time; when temperature was close to 7-10 °c and second time; when temperature was close to 7-10 °c at the end of winter) on two canola cultivars (licord and rgs). the total chlorophyll content was higher when 100 µm was applied at the second stage of application on licord cultivar. salicylic acid foliar application led to increase in seed yield of both cultivars. the highest plant height, seed weight and plant biomass were obtained from licord cultivar. the greatest pod number per plants was observed in licord which was treated with 100 µm salicylic acid at the first time while the highest seed number per pod was observed in the former cultivar which was treated with 200 µm salicylic acid at the first time. in general, results revealed that salicylic application increased canola growth and productivity of grain yield in both cultivars.

The Yield and Yield Components of Pea (pisum Sativum L.) as Influenced by Salicylic Acid

The effects of 0 M, 10 M and 10 M salicylic acid (SA) applied by three different modes (seed treatment, seed treatment plus foliar spray and foliar spray) in four pea (Pisum sativum L.) varieties viz., Meteor, Climax, Greenfeast and Rondo were evaluated. Among the varieties the highest green pod yield of 5255 Kg ha was obtained in variety Meteor followed by variety Greenfeast (4452 Kg ha). The ...

Multivariate Statistical Analysis to Yield of Canola under Drought Stress and Spraying of Gibberellin and Salicylic Acid

BACKGROUND: Drought stress is one of the most critical factors in the reduction of yield among plant growth factors. Salicylic acid is a regulator that plays a vital role in the physiological processes of the plant. Gibberellin is one of the plant growth-regulating hormones that have different effects on the growth and development of many plants during growth stages. <str...
