Studies were conducted to quantify leaf area damage to ‘Tahiti’ lime by citrus leafminer (CLM) (PhyllocnistLF citrella Stainton) and to relate leaf damage to larval density and the length of time mining per leaf. Visual estimates of leaf damage were similar among five evaluators and were positively correlated with image analysis determinations. The number of CLM larvae per leaf and the number o...

Two field and laboratory experiments were conducted to investigate the effects of superabsorbent polymer (SAP) and irrigation management on seed and essential oil yields of Cumin, as well as the impact of water quality on water holding capacity of SAP. Salinity had a negative effect on the amount of water absorbed by SAP (335 and 59 g H2O per g SAP, for distilled water and solution of 0.5% NaCl...

background and objectives: early watergrass (echinochloa oryzoides) is considered as a new-introduced species and then as a potential invader. investigation of competitive traits of this species, in comparison with barnyardgrass (e. crus-galli), one of the most important weeds in rice fields of guilan province, would be useful to determine its spreading possibility as an aggressive weed. theref...

waterlogging is one of the problems of cotton-growing in rainy regions which affects adversely plant growth in the early stages. so that rainfall causes waterlogging in early to mid spring in the fields without proper drainage. also, rainfall declines soil and environment temperatures. to investigate the effects of waterlogging period duration and temperature on vegetative properties and glycol...

The phenotypic diversity of potato, Solanum tuberosum was assessed using morphological traits. To verify, how this diversity is distributed among the main potato varieties in the growing areas in Iran. A total of eleven potato varieties, Ramose, Sante, Shepody, Marfona, Maradona, Milova, Santana, Boren, Cosima, Granola and Agria, were evaluated under vivo and situ experimental conditions in Isf...

A wetness duration experiment was carried out within a lily field situated adjacent to coastal dunes in the Netherlands. A within-canopy model was applied to simulate leaf wetness in three layers, with equal leaf area indices, within the canopy. This simulation model is an extension of an existing model. It appeared that in most cases leaf wetness started in the uppermost layer followed by the ...

The trial with 11 genotypes of winter oilseed rape (Brassica napus subsp. napus) with different provenance was based on experimental station Borovce near SCAR – RICP Piešťany (Slovak Republic) in autumn 2008 (the Trnavská pahorkatina locality, altitude 167 m, maize growing region). Approximately in weekly intervals, since beginning of April to middle of June 2009, for the purpose of growth anal...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...
