“…2.1. Total leaf area per plant (cm 2 ) Total leaf area per plant was calculated using the formula of Carleton and Foote (1965): leaf area (cm 2 ) = maximum leaf length × maximum leaf width × 0.75, 0.75 = correction factor.…”

To investigate the effect of exogenous application of triacontanol (TRIA) on 2 wheat (Triticum aestivum L.) cultivars (S-24 and MH-97) under salt stress, an experiment was conducted in a greenhouse under natural climatic conditions. Both cultivars were grown in full strength Hoagland's nutrient solution under nonsaline (0 mM NaCl) or saline (150 mM NaCl) conditions in sand culture. Three optimized TRIA levels (0, 10, and 20 µM) were used as foliar spray at 3 growth stages, i.e. vegetative, boot, and vegetative + boot stages. Ninety-two-day-old plants were subjected to data analysis. Salinity stress adversely affected various growth, physiological, and biochemical attributes in both wheat cultivars at all growth stages. Under salt stress, activities of superoxide dismutase (SOD) and peroxidase (POD) decreased (cv. MH-97), while those of catalase (CAT) and POD (cv. S-24) increased. Contents of hydrogen peroxide (H 2 O 2 ), malondialdehyde (MDA), Na + , and Clincreased in both wheat cultivars at all growth stages. A foliar spray of 10 µM TRIA was more effective in reducing the adverse effects of salt stress on growth, yield, and leaf water relations of wheat plants when applied at the vegetative or vegetative + boot growth stages.

“…After twenty days of flower formation five plants in which enthesis has been occured were randomly selected from each replicate and data for plant height, number of leaves, leaf area, fresh and dry weights of shoot and root and number of flowers per plant were recorded. Leaf area was calculated by using the formula of Carleton and Foote (1965). Lear area = maximum length x maximum width x Gorectionfactor (0.399).…”

Two varieties of canola (Brassica napus L.) Rainbow and Con I were treated with different levels of nitrogen (0, 60, 90 and 120 N kg haG 1 ) as urea before sowing and with split application of these levels before sowing and at the time of flower initiation. The data for plant height, number of leaves, leaf area, fresh and dry weight of root as well as shoot and number of flowers each for per plant showed an increasing trend as negating the difference of time of fertilizer application their application.

“…Same plants were used to count number of leaves plant -1 . For the measurement of leaf area, fully expanded leaves were selected and their area was calculated by recording their length and maximum width of leaf blade from the center, which were multiplying with constant factor (0.68) according to the method described by Carleton and Foote (1965). Stem diameter was measured from the base of plant (2 inches above soil surface) using digital caliper.…”

Genetic variability among the genotypes and their characterization are important for improving efficiency of breeding program (s). Genetic variation among 24 okra genotypes was analyzed for various horticultural traits including yield and fruit quality parameters. Heritability parameters including GV, PV, GCV, PCV, broad sense heritability (H 2 ), genetic advance (GA) and GA as percent of mean were also calculated. Results envisaged significant variation among genotypes for all the studied traits. 'Rama Krishna', 'Line Brand', 'Ikra-02', 'Ikra-04','Durga' and 'Patel' performed better on the basis of measured morphological and yield related traits including plant height, number of leaves plant and fruit tenderness at all picking intervals. This study revealed 'Ikra-02'and'Ikra-04'as potential local genotypes having good horticultural traits, especially the fruit tenderness and can be used in developing open pollinated and hybrid varieties of okra.
