Recent studies, including those from our laboratory, have provided evidence that by improving tuber Ca level we can reduce tuber internal defects and improve its storability. The purpose of the present study was to determine the influence of supplemental Ca fertilization on tuber size and tuber number. For this purpose, plantlets of Solanum tuberosum cv Russet Burbank raised in tissue culture w...
A two-year study (2007-2008) was carried out to explore the effect of split application of nitrogen fertilizer on yield, dry matter and harvest index of Marfona potato cultivar in Isfahan Agricultural Research Center, Iran. A randomized complete block design with a split plot arrangement with three replications was used. The main plots were three levels of nitrogen (100, 200 and 300 kg ha-1) an...
The central nervous system activity of the petroleum ether extract of Amorphophallus paeoniifolius tuber was examined in mice, fed normal as well as healthy conditions. The petroleum ether extract of Amorphophallus paeoniifolius tuber at the doses of 100, 300 and 1000 mg/kg showed significant central nervous system activity in mice.
باکتری زانتوموناس کمپستریس xanthomonas campestris))، باکتری تولید کننده صمغ زانتان می باشد. زانتان یک پلیمر خارج سلولی است که در صنایع غذایی و صنایع نفت کاربردهای فراوانی به عنوان ویسکوز کننده و امولسیون کننده دارد. از آنجا که این باکتری به طور طبیعی قادر به مصرف لاکتوز نیست؛ زانتان نمی تواند از محیط های پایه حاوی لاکتوز نظیر آب پنیر ( پساب صنعتی ارزان قیمت) تولید شود. به منظور حل این مشکل، اوپ...
Cultivation of OYSTER MUSHROOM (Pleurotus tuber-regium) on selected organic waste was carried out in the Microbiology Laboratory, Faculty of Science of the University of Port Harcourt. The study evaluated the effect of selected organic wastes on the growth and yield of Pleurotus tuber-regium (Fr. Singer). The organic wastes (Dry Substrates which include Maize cob, Cassava peelings, Plantain pee...
The degree to which vertebrate herbivores exploitatively compete for the same food plant may depend on the level of compensatory plant growth. Such compensation is higher when there is reduced density-dependent competition in plants after herbivore damage. Whether there is relief from competition may largely be determined by the life-history stage of plants under herbivory. Such stage-specific ...
BACKGROUND AND AIMS Spring geophytes require a period of low temperature for proper flower development but the mechanism that underlies the relationship between cold treatment and flowering remains unknown. The present study aims to compare the developmental anatomy and carbohydrate content of the tuberous geophyte Corydalis bracteata growing under natural winter conditions from 10 to -10 degre...
Ultrafine-grained (UFG) pure copper of 280 nm grain size was prepared by equal-channel angular pressing. Tensile tests, strain-rate change tests and temperature change tests were conducted on UFG Cu in the temperature range between 77K and 373K. As usual, tensile strength increased as temperature decreased and strain rate increased. The activation energy of deformation increased linearly with t...
