The effect of exogenous application of various levels of -1 ethrel (500, 1000, 1500 and 2000 μmol l ); Gibberrelic Acid (GA 15, 30, 45 3 ; -1 -1 and 60 μmol l ) and Maleic hydrazide (MH; 200, 400, 600 and 800 μmol l ) on sex expression of bottle gourd (Lagenaria siceraria Molina) plants cv. Faisalabad Round was investigated under field conditions in National Agricultural Research Centre, Islama...

The inheritance of sex expression in cucumber (Cucumis sativus) and other cucurbits is well documented; however, the genetics of female sex (gynoecism) expression in bitter gourd (Momordica charantia) has not been described. Inheritance of gynoecism in bitter gourd was studied in a 100% gynoecious line (Gy263B). The F(2) and testcross segregation data revealed that gynoecism in Gy263B is under ...

septoriosis is one of the most important disease in pistachio tree worldwide and is incited by several species of septoria among which s. pistacina islimited to mediterranea regions and recently reported on pistacia vera in golestan province of iran (aghajani et al. 2009. austr. plant dis. notes 4: 29-31). leaf samples of p. vera  from ghazvin (fig. 1) collected in october 2013, and samples fro...

The relationship of leaf and fruit transpiration rates with the incidence of spongy tissue in mango cultivars Dashahari (free from spongy tissue) and Alphonso (susceptible to spongy tissue) was investigated. Leaf transpiration rates were similar in both the cultivars, however the fruit transpiration rates were significantly higher in cv. Dashahari. Artificially induced variations in fruit trans...

ABSTRACT The barley cv. Bolivia carries two leaf rust (Puccinia hordei) resistance genes, Rph2 and Rph6, and is the only known source of the latter gene. A resistant line (Bolivia-Rph6) carrying Rph6 only was obtained in the F(4) generation of a cross between cv. Bolivia and the susceptible cv. Bowman via progeny testing with differential isolates of the leaf rust pathogen. Genetic analyses and...

The chrysanthemum (Dendranthema X grandiflorum) belongs to the family Asteraceae and it is one of the most popular flowers in the world. Viroids are the smallest known plant pathogens. They consist of a circular, single-stranded RNA, which does not encode a protein. Chrysanthemums are a common host for two different viroids, the Chrysanthemum stunt viroid (CSVd) and the Chrysanthemum chlorotic ...

The aim of this study was to investigate the effects 1.5, 3.0 and 4.5 kJ/m2 UV-C illumination doses on postharvest quality fresh fig (cv. Bursa Siyahi). For purpose, fruit were stored at 0 ºC temperature with 90-95% humidity for 21 days some fruits kept 20 °C 3 simulate a period shelf-life. treatments did not affect firmness, total soluble solids, titratable acidity content during cold storage ...
