The relation of polyamine catabolism in the response of Pisum sativum to salinity stress was investigated. Pea seedlings were grown in increasing concentrations of Na<sup>+</sup> or K<sup>+</sup> or at different concentration ratios of these ions. We studied the effect of Ca<sup>2+</sup> supplementation on plants exposed to salinity stress. The parameters measured in the roots and shoots of pea seedlings included biomass production, levels of Na<sup>+</sup>, K<sup>+</sup>, Ca<sup>2+</sup> and polyamines and activity of enzymes of polyamine catabolism: diamine oxidase, aminoaldehyde dehydrogenase and peroxidases. Salinity induced increased polyamine levels and higher activity of enzymes participating in polyamine degradation. Supplementation of Ca<sup>2+</sup> had a positive effect on biomass production and in most cases it stabilised both the polyamine level and the activity of the studied enzymes. Our results confirm the role of aminoaldehyde dehydrogenase and polyamine catabolism in defence mechanisms of pea plants under salinity stress.

Chemical Contents

This study was conducted to determine the correlation between of salinity stress on growth and phenolic compounds in rice. It was observed that salinity stress caused a significant decrease in shoot lengths, fresh and dry weights of all rice varieties. Under salinity stress, changes of chemical contents also differed among phenolic compounds and rice cultivars. Total phenolics and flavonoids, and contents of vanillin and protocatechuic acid in tolerant varieties were strongly increased, whereas in contrast, they were markedly reduced in the susceptible cultivar. Ferulic acid and p-coumaric acid were detected only in tolerance rice. Vanillin and protocatechuic acid may play a role, but ferulic acid and p-coumaric acid may be much involved in the tolerant mechanism against salinity stress. Ferulic acid and p-coumaric acid and their derivatives are able to be exploited as promising agents to reduce detrimental effects of salinity stress on rice production.

In order to study the physiology of perception of saline stress in ‘Common Sunki’ mandarin hybrids, an experiment was realized in a greenhouse at the CCTA - UFCG, Pombal, PB, Brazil,using using a randomized block design with a 2x4 factorial , with two levels of salinity (0.3 and 4.0 dS m-1) and four ‘Common Sunki’ mandarin hybrids (1 - TSKC x CTARG–019; 2 - TSKC x CTSW–028; 3 - TSKC x CTSW–033 and 4 - TSKC x CTSW-041), with three replications and four plants per plot. The plants were grown hydroponically and 90 days after sowing, a saline water solution was applied on rootstocks and evaluations of gas exchange and chlorophyll fluorescence were carried out 24 and 48 hours after saline stress. Changes on physiologic conditions were observed in the hybrids TSKC x CTSW - 028, TSKC x CTSW - 033 and TSKC x CTSW - 041 during the first 24 hours of saline stress. Fot the hybrid TSKC x CTARG – 019, changes were observed after 48 hours od salinity stress. According to salinity tolerance, the hybrids could be classified as follows: TSKC x CTARG - 019 > TSKC x CTSW - 028 = TSKC x CTSW – 041 > TSKC x CTSW - 033.

Fingernail Clams

Fingernail clams (Muscu1ium transversum) are dominant bottom-dwelling animals in some waters of the midwest U.S. These organisms are key links in food chains leading from nutrients in water and mud to fish and ducks which are utilized by man. In the mid-1950’s, fingernail clams disappeared from a 100-mile section of the Illinois R., a tributary of the Mississippi R. Some factor(s) in the river and/or sediment currently prevent clams from recolonizing areas where they were formerly abundant. Recently, clams developed shell deformities and died without reproducing. The greatest mortality and highest incidence of shell deformities appeared in test chambers containing the highest proportion of river water to well water. The molluscan shell consists of CaCO3, and the tissue concerned in its secretion is the mantle. The source of the carbonate is probably from metabolic CO2 and the maintenance of ionized Ca concentration in the mantle is controlled by carbonic anhydrase. The Ca is stored in extracellular concentric spherical granules(0.6-5.5μm) which represent a large amount of inertCa in the mantle. The purpose of this investigation was to examine the role of raw river water and well water on shell formation in the fingernail clam.
