BackgroundMetals are one of the micro molecules required by living cell to do their biochemical functions. Out of a list of metals few are very important and useful to cells while few are required in very minute amount and their higher concentration harm or cause adverse effects on living forms. Copper and ferrous are commonly counted as essential metals to plant cells but sometimes their higher concentration is harmful to plant cells. Copper is commonly counted as important metal to plant cells but sometimes their higher concentration is harmful to plant cells.ResultsIt was found that higher concentration of copper and ferrous showed reduction in germination percentages and gemination time of investigated plant while chromium shown lethal impacts on seed germinationConclusionsIn the present study effects of copper, chromium and nickel was studied for total sugar and protein content of widely cultivated pulses i.e. Glycine max. Collectively present study showed that higher concentration of copper and nickel has adverse effects on Glycine max total sugar and protein content while chromium has lethal impacts at lower concentration also.
Barleria prionitis (Acanthaceae) is an important medicinal plant distributed throughout the various regions of India and useful in urinary and paralytic affection, stomach disorders, catarrh, cough and anasaraca and lacerated sole. In the present investigation an attempt was made to study the anatomy of root, stem, lamina, midrib, petiole, stomata and trichomes as well as histochemical localization of various substances viz., calcium oxalate, lignin, suberin, lipids in the organs of Barleria prionitis. The present study revealed that the plant distinguishing microcharacters viz., bicollateral vascular bundles, internal phloem, unibiseriate xylem rays, inverted omega shape vascular bundle, diacytic stomata and eglandular as well as glandular trichomes which are useful in solving taxonomic problems and pharmacognosy. They have significance in identification of crude drugs from this taxon.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
