abstract

a study was conducted at the research station of department of horticultural science (tehran university, karaj) to evaluate the effects of water stress on yield, growth and some physiological parameters in iranian melon. the experiment was set out in a split plot design with three replicates. treatments consisted of factorial arrangement of three irrigation levels (starting irrigation at -50, -65 and -75 cbar) and two iranian melon landraces (zard jalali and suski sabz). the results indicated that the drought levels exerted significant effects on leaf area, stem length, proline accumulation, fruit weight as well as yield. water stress caused significant reduction in fruit weight and melon yield. the lowest leaf area (31533 mm2), stem length (258.56 cm), fruit weight (2898.1 gr) and yield (57.96 t/ha) as well as the most proline content (1.455 mg/g fw) were obtained for the case of the most sever water stress treatment (-75 cbar). landrace did not significantly differences for the studied traits.

Effect of water-deficit stress on fruit yield, antioxidant activity, and some physiological traits of four Iranian melon genotypes

To evaluate the effect of water-deficit stress on the yield, antioxidant activity, and physiological traits of four Iranian melon genotypes (“Khatooni,” “Suski-Sabz,” “Zarde-Tabriz,” and “Shiari”), an experiment was conducted. The irrigation levels were: (1) control (100%ETc); (2) deficit irrigation 66% (66%ETc); and (3) deficit irrigation 33% (33%ETc). The results showed that the yield and rel...

Effects of Water Salinity on Growth Indices and Physiological Parameters in Some Wild Pistachio

The effect of four water salinity levels (0.75, 5, 10 and 15 dS.m -1 ) on growth indices and physiological parameters in some wild pistachio (P. atlantica, P. atlantica subsp. kurdica, P. atlantica subsp. mutica and P. atlantica subsp. cabulica) were investigated under greenhouse conditions. Leaf dry weight was reduced to about 30-54% at ECw 10 dS.m -1 . Chemical analysis of shoot and root indi...
