The present study an attempt has been made to investigate the effect of Seaweed Liquid Fertilizer of Rosenvigea intricata with or without chemical fertilizer on seed germination, growth, yield, pigment content and soil profile of Abelmoschus esculentus was analyzed. The seed germination, shoot length, root length, number of lateral roots, number of leaves, number of vegetables, length of vegeta...

The chlorophyll content is one of the most important traits selected by breeders, and it is controlled by quantitative trait loci (QTLs) derived from natural variations in rice. We analyzed the QTL controlling chlorophyll content by using 94 RILs derived from a cross between 2 japonica rice cultivars, Lijiangxintuanheigu (LTH) and Shennong265 (SN265). Twenty-two QTLs controlling chlorophyll con...

Anthocyanins are secondary metabolites that contribute to red, blue, and purple colors in plants and are affected by light, but the effects of low light on the physiological responses of purple pak-choi plant leaves are still unclear. In this study, purple pak-choi seedlings were exposed to low light by shading with white gauze and black shading in a phytotron. The responses in terms of photosy...

In order to increase in chickpea quality and agroecosystem sustainability, field experiments were carried out in 2007 and 2008 growing seasons. In this research the effects of different organic, chemical and biological fertilizers were investigated on grain yield and quality of chickpea. Experimental units were arranged in split-split plots based on randomized complete blocks with three replica...

A segregating F4 population from the cross between drought sensitive (Yecora Rojo) and drought tolerant (Pavon 76) genotypes was made to identify SRAP markers linked to leaf chlorophyll content, flag leaf senescence and cell membrane stability traits in wheat (Triticum aestivum L.) under water-stressed condition. The parents and 150 F4 families were evaluated phenotypically for drought toleranc...

Spring wheat (Triticum aestivum L., cv. ‘Minaret’) was grown in open-top chambers and exposed to two CO2 concentrations (ambient and 680 ppmv) and two O3 concentrations (ambient and ambient +50 or +90 ppbv) either from anthesis onwards or for the entire growing season. The aim of the experiment was to test whether elevated CO2 could provide ‘protection’ to the crop against the damaging effects ...

A trial for estimating leaf chlorophyll content based on leaf reflectance was conducted for three major plant species in Daegu, South Korea. To estimate the chlorophyll content in a leaf, we measured the leaf elongation and related the leaf reflectance to its absorbance. Leaves of the target species were found to start elongating around the middle of April and continued elongation until the mid...

Drought is a major abiotic stress that is threatening the production and the survival of many crops such as cereals. The response of three Aegilops crassa accessions (C1, C2 and C3) that inhabit areas with different rates of rainfall and durum wheat to controlled drought (with soil moisture of 50% field capacity) was tested in terms of changes in: relative water content, chlorophyll content, ch...
