LED induced chlorophyll fluorescence analysis is employed to investigate the effect of water deficit and salt stress upon the growth process of Jatropha curcas L.. Red(Fr) and far-red(FFr) chlorophyll fluorescence around 685 nm and 735 nm, respectively, were observed and examined as a function of the stress intensity(salt concentration and water deficit).(More)
This study investigated the ability of a light emitting diode (LED) to induce somatic embryogenesis (SE), shoot multiplication, and rooting of sugarcane (RB98710). We also accessed the effects on acclimatization. MS medium was used for all stages and was supplemented with different concentrations of growth regulators according to the culture stage. The(More)
Two castor bean cultivars were subjected to water stress induced by polyethylene glycol 6000 (PEG) under in vitro conditions. After 15 days, a reduced percentage of surviving plants, leaf abscission and greater leaf cuticular wax content were observed, accompanied by reduced water loss through the leaves. PEG also caused a decrease in soluble protein(More)
