“…Melon yield depends on the combination of scion and rootstock, and the content of inorganic ions in the leaves is altered by the rootstock [16]. Santa-Cruz et al [37] observed that the same rootstock differently affects growth of scions from different tomato cultivars. Thus, the root surface area and root permeability in grafted plants may be affected by the scion cultivar.…”

Grafting is widely established in agriculture and provides practical advantages for vegetable production. We investigated physiological differences between the grafted combinations of Dutch (Starbuck and Maxifort) and Japanese (Reiyo, Receive and Magnet) tomato cultivars. Plants were grown hydroponically until the flowers on the first truss bloomed, and the following parameters were measured: fresh weight of the aerial parts, root surface area, root permeability (by using a pressure chamber), and water potential of exudates (by using an isopiestic psychrometer). The Starbuck/Maxifort combination had higher values of the aerial part weight, root surface area, and root permeability than Reiyo/Receive, whereas Reiyo/Maxifort tended to have higher values of these parameters than Reiyo/Receive and Reiyo/Magnet. Maxifort had a significantly larger root surface area than Receive, but root permeability was not significantly different. InReiyo/Maxifort and Starbuck/Receive, these parameters were not significantly different except for a single comparison of root permeability. Thus, root permeability and root surface area may depend not only on the rootstock but be also affected by scion in grafted plants. Water potential of exudates was similar in most combinations and experiments. This shows that three rootstock cultivars provided similar nutrient concentrations even with different scions.

Comparison of ROS formation and antioxidant enzymes in Cleome gynandra (C4) and Cleome spinosa (C3) under drought stress

a b s t r a c tDifferences between antioxidant responses to drought in C 3 and C 4 plants are rather scanty. Even, we are not aware of any research on comparative ROS formation and antioxidant enzymes in C 3 and C 4 species differing in carboxylation pathway of same genus which would be useful to prevent other differences in plant metabolism. With this aim, relative shoot growth rate, relative water content and osmotic potential, hydrogen peroxide (H 2 O 2 ) content and NADPH oxidase (NOX) activity, antioxidant defence system (superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), ascorbate peroxidase (APX), glutathione reductase (GR) enzymes and their isoenzymes), CAT1 mRNA level, and lipid peroxidation in seedlings of Cleome spinosa (C 3 ) and Cleome gynandra (C 4 ) species of Cleome genus exposed to drought stress for 5 and 10 day (d) were comparatively investigated. Constitutive levels of antioxidant enzymes (except SOD) were consistently higher in C. spinosa than in C. gynandra under control conditions. CAT1 gene expression in C. spinosa was correlated with CAT activity but CAT1 gene expression in C. gynandra at 10 d did not show this correlation. Drought stress caused an increase in POX, CAT, APX and GR in both species. However, SOD activity was slightly decreased in C. gynandra while it was remained unchanged or increased on 5 and 10 d of stress in C. spinosa, respectively. Parallel to results of malon dialdehyde (MDA), H 2 O 2 content was also remarkably increased in C. spinosa as compared to C. gynandra under drought stress. These results suggest that in C. spinosa, antioxidant defence system was insufficient to suppress the increasing ROS production under stress condition. On the other hand, in C. gynandra, although its induction was lower as compared to C. spinosa, antioxidant system was able to cope with ROS formation under drought stress.

“…Plants in saline conditions usually accumulate inorganic anions, such as Cl - (Santa-Cruz et al, 2002), NO 3 -, and SO 4 2-, or synthesize organic anions to neutralize the high concentrations of cations and maintain ionic balance (Yang et al, 2007).…”

Based on Glycine gracilis growth and ion homeostasis testing, neutral salt (NS)and alkaline salt (AS) stress were characterized and the responses of G. gracilis were investigated.The injurious effects of AS on G. gracilis were obviously stronger than those of NS.The effects of both stresses on the Na + content and Na + /K + ratio were similar at low concentrations, but as the stress increased, the effects of a greater Na + content and Na − levels to compensate for the shortage of inorganic anions.G. gracilis seedling showed a special nutritional metabolism and some growth adaptability under salt stress.
