The present study is focused on the possible mediatory role of salicylic acid (SA) in photosynthesis under cadmium (Cd) toxicity. Maize seeds were sterilized and divided into two groups. One half of the seeds was presoaked in 500 μM SA solution for 6 h and then both groups were allowed to germinate for 3 days. Plants were grown for 12 days in Hoagland solution at 22/18 oC under 16/8-h light/ da...

Four ecotypes of the species Lycopersicon cheesmanii ssp. minor (Hook.) C.H. Mull. from the Galapagos Islands were compared with L. esculentum Mill cv. VF 36 with respect to salt tolerance. The L. cheesmanii ecotype that proved most salt-tolerant was selected for detailed comparison with the L. esculentum cultivar. Plants were grown in modified Hoagland solution salinized with synthetic seawate...

Sustainable agriculture relies on replacing fossil-based mineral fertilizers, which are highly cost-energetic to produce, and demand extensive use of scarce natural resources. Today, agronomic practices within the concept circular economy emerging and, as such, exploitation digestate a biofertilizer soil amender is extensively investigated. This study aimed at evaluating potential liquid sole n...

One of the main constraints in Aloe vera production is poor information about optimum nutrients that are helpful for growth and production. The objective of this study was to optimize nutrient solution for Aloe vera cultivation in soilless culture. Therefore, to determine the best nutrients the experiment was conducted in a greenhouse during 2011 in the Agricultural Faculty, University of Guila...

the effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (brassica napus l.) grown in the hoagland solution. the growth of treated plants was inhibited under lead stress. lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgl-1 of pb. hyola308 cultivar showed low biomass...

salinity is a major environmental problem in arid and semi-arid areas. chickpea (cicer arietinum l.), like other legumes is sensitive to salinity. therefore, selection of genotypes to grow on saline areas is important. eleven chickpea genotypes (as sub plots) were grown in the greenhouse conditions on a medium containing different nacl concentrations (8 and 12 dsm-1) and control (hoagland solut...
