“…In agreement with previous studies (Zribi et al 2009;Nakaune et al 2012;Chinsamy et al 2013), common symptoms of salinity stress on tomato growth including senescence, accelerated development and growth inhibition contributed to the reduced PVI (with increasing concentrations of NaCl) observed in the current study. Generally, salt stress leads to changes in growth, morphology and physiology of the roots, which in turn affect water and ion uptake as well as hormone signaling and perception especially to the shoot (Cuartero and Fernández-Muñoz 1998).…”

“…Globally, it is a widely researched plant with emphasis on different approaches geared toward improving its growth (Arthur et al 2012;Nakaune et al 2012) and stress alleviation or tolerance (Cuartero and Fernández-Muñoz 1998;Fan et al 2011;Gálvez et al 2012;Chinsamy et al 2013). Recently, the potential of INCYDE has been demonstrated in micropropagation (Aremu et al 2012a), under cadmium stress conditions (Gemrotová et al 2013) and biotic stress (Reusche et al 2013).…”

The effect of 2-chloro-6-(3-methoxyphenyl)aminopurine [inhibitor of cytokinin degradation (INCYDE)] at 10 nM on growth, biochemical and photosynthetic efficiency in sodium chloride (NaCl)-stressed (75, 100 and 150 mM) tomato plants was investigated. NaCl-induced decline in plant vigor index was slightly reversed by both drenching and foliar application of INCYDE. Foliar application of INCYDE significantly increased the flower number in the control and 75 mM NaCl-supplemented plants, while drenching was more effective in 150 mM NaCl-stressed plants. Antioxidant enzymes (peroxidase, catalase and superoxide dismutase) were enhanced in the presence of INCYDE in the control and NaCl-stressed plants. Higher concentration of malondialdehyde (MDA) associated with oxidative (lipid peroxidation) damage in leaf tissue which was evident in the presence of NaCl stress was significantly attenuated with the drenching and foliar application of INCYDE. Regardless of NaCl concentration, application of INCYDE had no significant influence on maximum quantum efficiency of photosystem II. However, the reduced quantum yield of photosystem II and coefficient of photochemical quenching under continuous illumination with actinic light at four intensities (264, 488, 800 and 1,200 µmol m(-2) s(-1)) in NaCl-stressed (100 and 150 mM) tomato plants were significantly alleviated by drenching application with INCYDE. Non-photochemical quenching of the singlet excited state of chlorophyll a and relative electron transfer rate were generally higher in INCYDE-treated plants than in the controls. From an agricultural perspective, these findings indicate the potential of INCYDE in protecting plants against NaCl stress and the possibility of enhanced productivity.

“…Both VCL and GA 3 (10 -5 M) also increased seedling fresh weight when compared to the control. Proline accumulation which is a metabolic response to abiotic stress has been shown to be influenced by the presence of VCL in different crops (Chinsamy et al 2013;Singh et al 2014). Recently, the beneficial role of VCL under limited-nutrient conditions in greenhouse grown tomato (Arthur et al 2012) and three medicinal plant species (Aremu et al 2014) was demonstrated.…”

“…Evidence of similar physiological effects have been observed in plants treated with VCL. For example, application of VCL improved root, shoot, stem and leaf growth, the development of tomatoes and the accumulation of proline when grown under elevated saline conditions (Chinsamy et al 2013). BRs are also known to induce salinity tolerance via regulation of proline metabolism in plants (Iqbal et al 2014).…”

“…Vermicompost are made by controlled aerobic and thermophilic biological transformation to attain the required pasteurization and a specified level of maturity (Campitelli and Ceppi 2008). The increasing acceptance of vermicompost products is due to numerous benefits including their usefulness in plant growth media and soil ameliorants (Theunissen et al 2010;Aremu et al 2012) as well as alleviation of nutrient deficiency (Arthur et al 2012;Aremu et al 2014) and other abiotic stress conditions (Chinsamy et al 2013).…”

Cytokinins, auxins, abscisic acid, gibberellins (GAs) and brassinosteroids (BRs) as well as the phenolic acid content in three batches of vermicompost leachate (VCL) were quantified using ultra high performance liquid chromatography-tandem mass spectrometry. N 6 -isopentenyladenine formed the major (60 %) proportion of the CK content while dihydrozeatin had the lowest (\0.02 %) concentration. Indole-3-acetic acid ranged from approximately 0.55-0.77 pmol/mL. A total of 18 GAs including bioactive forms and metabolic end products were observed in the VCL samples. Cathasterone had the highest (2,500-3,200 fg/mL) concentration while brassinolide was the lowest (1-5 fg/mL) abundant BRs found. Phenolic acids quantified were protocatechuic acid (3-3.6 lg/mL), p-hydroxybenzoic acid (2.5-2.8 lg/mL), p-coumaric acid (1-1.7 lg/mL) and ferulic acid (0-4 lg/mL). These results provide an indication of the rich diversity in natural PGRs and phytochemicals in VCL which may inevitably contribute to the numerous favorable physiological responses elicited by VCL application to plants.
