ABSTRACT: In the present investigation, Maize seeds of hybrid NK 6240 and 900M Gold were exposed to UV-B (280-320 nm) for periods of 40 and 60 minutes and compared with the control without exposer to UV-B. The biochemical changes associated with UV-B induced resistance were investigated by determination of proline concentration, total soluble sugars, total soluble protein, malondialdehyde content and free amino acids from leaves and roots. Also comparison for germination percentage between control and treated seeds was carried along with biochemical traits. Analysis of variance explains both the hybrids were significantly different in germination percentage, total soluble sugars, proline and free amino acids. Whereas both treatments showed high significant variation for all the studied traits, but genotype × treatment interaction was non-significant for all the traits. 40 minutes UV-B treated seeds showed reduced total soluble sugars and increased malondialdehyde, proline and total soluble protein content. In 60 minutes UV-B treatment, decrease in free amino acids, proline, percentage of germination, and total soluble protein and increase in total soluble sugars was observed.

Cadmium Treatment

The effect of foliar application of kinetin on the growth and some physiological processes of pea plants growing in soil supplemented with 25 or 50&micro;M Cd were studied. Cadmium treatment inhibited the growth rate, chlorophyll (Chl) content, net photosynthesis (P<sub>N</sub>), content of soluble sugars and free amino acids of either shoots or roots. The application of kinetin (kin) enhanced the growth rate, Chl content, P<sub>N</sub>, soluble sugars and free amino acids content of shoots and roots; dark respiration rate (R<sub>D</sub>), contents of soluble protein and proline were increased by cadmium treatment. The addition of kinetin to Cd-stressed plant reduced R<sub>D</sub>, soluble protein and proline content. Considerable variations in the content of Na<sup>+</sup>, K<sup>+</sup>, Ca<sup>2+</sup> and Mg<sup>2+</sup> were induced by Cd-treatments. Foliar application of kinetin exhibited a favorable effect on the accumulation of some ions and antagonized or ameliorated the inhibitory effect of Cd stress on some others.

Increasing the supply of sulfur (S) to forage plants can change their nitrogen (N) metabolism, causing changes in the N : S ratio that can potentially affect forage production and quality. The present study was focussed on revealing how supply (low, intermediate, high) of S affects amino acid composition and concentrations of total S, total N, sulfate-S, nitrate-N, and soluble protein in the leaves of tropical pasture species. Greenhouse experiments were conducted in ground quartz (inert solid substrate) culture to examine the effect of S supply in two tropical species: Panicum maximum cv. Tanzania (Guinea grass) and Stylosanthes guianensis cv. Mineirão (stylo). Because legumes have greater S requirement than do grass species, application levels of S varied according to the species. Guinea grass was grown with 0.10, 0.55, 1.00, 1.45, and 1.90 mmol L−1 of S, and stylo with 0.10, 0.70, 1.30, 1.90 and 2.50 mmol L−1 of S. Plants of both species were harvested on two occasions. Low S availability (0.10 mmol L−1) caused a nutritional imbalance with N in Guinea grass and stylo plants, as shown by a high N : S ratio (>60 : 1), and high concentrations of nitrate-N and free amino acids in plant tissues. Increased S supply regulated the N : S ratio at values close to 20 : 1, which provided N and S concentrations more suitable for protein synthesis and optimum forage production for both forage species. Asparagine was the predominant amino acid present in S-limited Guinea grass, whereas arginine was more abundant in S-limited stylo. This result indicates that a limitation of S increases nitrate-N and free amino acids while decreasing plant growth rates and soluble protein concentrations in these forage species.

The present investigation was aimed to assess the effect of different concentrations of elicitors viz., salicylic acid (SA) and benzothiadiazole (BTH) on physiomorphological and biochemical parameters of Brassica juncea and B. napus cultivars. The field experiment was conducted during 2012-13 at Punjab Agricultural University, Ludhiana, India. Four different treatments of elicitors and a fungicide treatment were given to 10 week old plants up to four consecutive weeks. Content of total soluble protein, free amino acids, total sugars and reducing sugars ofleaves of both B. juncea and B. napus were evaluated after each spray. The content of total soluble protein increased, whereas the contents of free amino acids, total sugars and reducing sugars decreased in all the treatments after each spray. Among all the treatments, the combinations of elicitors, i.e., BTH (3 ppm) + SA (33 ppm) and BTH (7 ppm) + SA (17 ppm) exhibited maximum contents of total soluble protein, free amino acids, total sugars and reducing sugars than control in both the cultivars. These treatments were more pronounced in increasing plant height, internodal distance and number of pods per plant in both the cultivars. Our results suggest that the combinations of elicitors act synergistically to promote growth and metabolic activities in B. juncea and B. napus cultivars leading to the induction and regulation of disease resistance.

Effects of the herbicides SC-0224 and glyphosate on the pool levels of free amino acids, soluble protein, and protein synthesis in inflated duckweed were compared. SC-0224 caused larger increases than glyphosate in the pool levels of amino acids; the increases caused by SC-0224 were similar, however, to those caused by trimethylsulfonium iodide (TMS-I). Expressed on a per gram fresh weight basis, none of the treatments changed soluble protein or the incorporation of14C-leucine into soluble protein. On a per flask basis (allowing for decreased growth in treated flasks), both herbicides and TMS-I decreased soluble protein and14C-leucine incorporation. Decreases in soluble protein and14C-leucine incorporation were equal for SC-0224 and TMS-I but larger than for glyphosate. These data indicate that differences in the phytotoxicity of SC-0224 and glyphosate may be due to the action of the trimethylsulfonium portion of the SC-0224 structure.
