Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

The ch4 mutant of sweetclover (Melilotus alba) has previously been demonstrated to be partially deficient in chlorophyll and to have a higher ratio of chlorophyll a to b than normal plants. We were able to substantiate these findings when plants were grown at 23 degrees C and lower (permissive temperatures). However, when grown at 26 degrees C (nonpermissive temperature) the plants produced sma...

The effects of UV-B radiation on the amount of chlorophyll a, b, carotenoids, flavonoids, anthocyanins, and polyphenols of three soybean cultivars was studied. After germination in the incubator, plants were put in pots of soil and during 3 weeks and irrigated with Hoagland solution every day. After 3 weeks, plants were exposed to UV-B for 20 min every day for a week. In each cultivar, UV-B red...

The effects of lead, copper, cadmium and mercury on the content of chlorophyll, proline, retinol, α-tocopherol and ascorbic acid were investigated in 17-day-old bean seedlings (Phaseolus vulgaris L.) grown in Hoagland solution spiked with various concentrations of Pb, Cu, Cd and Hg. Control and heavy metal-treated plants were grown for 10 days in Hoagland solution. Content of total chlorophyll ...

Amount of chlorophyll content, Proteins, Carbohydrates and RNA has been studied in ten taxa of Mosses. The study also embodies the specific activity of enzymes α-amylase, ß-amylase, Proteases and polyphenol oxidases. It has been found that carbohydrate content is more than protein content in Atrichum pallidum, Thuidium recognitum, Brachythecium kamounense and Funaria hygrometrica, whereas, tota...

there is little information available on morphological and agronomic traits, as well aschemical compositions of iranian mint landraces. this study was conducted to investigate themorphological, agronomic and oil content characteristics of iranian mint landraces using twelvelandraces, three of which belong to mentha longifolia, and the remaining, mentha spicata l, originatedfrom central regions ...

in order to study the effects of water deficit stress and foliar application of chitosan in safflower (carthamus tinctorius l.), a pot experiment was conducted in 2009. experimental design was a randomized complete block in factorial arrangement with three replications. experimental factors were water deficit levels (unstressed (control) and 70% available water depletion from soil (water defici...

Response of winter wheat (Triticum aestivum L.) spectral reflectance characteristics to chlorophyll content in planting densities application rate. Bulg. J. Agric. Sci., 19: 1190-1197 The leaf chlorophyll content of wheat is one of important agronomic parameters to anal...

Global climate change not only leads to elevated seawater temperatures but also to episodic anomalously high or low temperatures lasting for several hours to days. Scleractinian corals are detrimentally affected by thermal fluctuations, which often lead to an uncoupling of their mutualism with Symbiodinium spp. (coral bleaching) and potentially coral death. Consequently, on many Caribbean reefs...
