The chlorophyll fluorescence imaging technique is a valuable tool to study the impact of heavy metal stress in plants. The aim of this paper was to investigate the influence of Cd on photosynthetic apparatus of white cabbage (Brassica oleracea subsp. capitata f. alba) plants. Two cabbage cultivars ‘Ditmarska Najwcześniejsza’ (‘DN’; early) and ‘Amager Polana’ (‘AP’; late) were used. Cd was appli...

to explore the function of light-harvesting complex protein (lhcp) in arabidopsis growth and development, the leclere and bartel seed collection was screened. in this collection randomly cloned cdnas are expressed under the camv35s promoter. a pale green line has been identified and characterized in more details. analysis of the inserted cdna in the pale green line showed it encodes lhcb1 prote...

In the present study, we investigated changes in chlorophyll fluorescence, photosynthetic parameters and fruit yields, as well as fruit phytochemical accumulation of strawberry (Fragaria ananassa Duch.) that had been cultivated in a greenhouse under different combinations of light intensity and temperature. In plants grown with low light (LL) photosystem II chlorophyll fluorescence was found to...

abstract planting of olive (olea europaea l.) tree due to salt and drought tolerance and ever green habit increasingly is considered in urban landscape in recent years. the low resistance to cold has been a major problem in using this tree in temperate and cold zones. so, determination of frost resistance cultivars is one of the important measures for use of this tree in urban landscape. to eva...

Hydrogen gas (H2) and carbon monoxide (CO) are involved in plant growth and developmental processes and may induce plant tolerance to several stresses. However, the independent roles and interaction effect of H2 and CO in adventitious root development under drought conditions have still not received the needed research attention. We hypothesize that there exists crosstalk between H2 and CO duri...

Salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. The present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (Nitraria schoberi). Thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...

in order to study the effect of foliar zinc spraying on photosynthetic pigments and yield of chickpea under water stress conditions, a factorial experiment carried out based on randomized completely block design (rcbd) with three replications in university of mohaghegh ardabili agricultural research station in 2012. the treatments consisted of three levels of irrigation (irrigated at planting, ...
