In this investigation, the effect of salt stress on Portulaca oleracea L. was monitored at salinity levels 100 and 300 mM NaCl. At a concentration NaCl there decrease in stomatal conductance (gs) simultaneously with an increase CO2 assimilation (A) beginning exposure (day 3). However, leaf water potential (ψw), substomatal (Ci), maximum quantum yield photosystem II (Fv/Fm), proline malondialdehyde (MDA) content remained unchanged. Exposure to caused gs from day 3 potential, assimilation,...

Salt stress severely reduces growth and yield of plants. Considering the positive effects selenium (Se) chitosan (Cs) separately against abiotic stress, in these experiments, we synthesized chitosan–selenium nanoparticles (Cs–Se NPs) investigated their ability to reduce negative salt on some biochemical parameters bitter melon (Momordica charantia). Bitter plants were grown at three NaCl salinity levels (0, 50, 100 mM) a foliar spray Cs–Se NPs 10, 20 mg L−1) was applied. Some key...

Crops, such as white cabbage (Brassica oleracea L. var. capitata (L.) f. alba), are often infested by herbivorous insects that consume the leaves directly or lay eggs with subsequent injury caterpillars. The plants can produce various defensive metabolites free radicals repel to avert further damage. To study production and effects of these compounds, large butterflies, Pieris brassicae flea beetles, Phyllotreta nemorum, were captured in a field applied cultivated lab. After insect...
