The endogenous levels of indole-3-acetic acid (IAA) and phenyl acetic acid (PAA) were estimated in developing seeds of two different varieties of Cajanus cajan: Black seeded variety (V1, big seeded) and B. D. N2 (V2, small seeded). Antibodies against IAA and PAA were raised in rabbits. By competitive ELISA, free and conjugated IAA and free forms of PAA were estimated. Growth analysis of seeds w...

The objectives of this study were to evaluate effects of ambient and double ambient [ CO2 ] at a range of growing temperatures on photosynthesis, respiration, transpiration, water-use efficiency and dry matter accumulation of cotton plants (Gossypium hirsutum L., cv. DPL 50). In Experiment I, plants were grown outdoors untiJ first bloom, then transferred into naturally lit growth chambers and g...

for evaluation of iranian onion morphotypes potentials and application of them in breedingprogrames, seeds of 23 iranian onion morphotypeswere collected from east azarbaijan (redazarshahrmorphotypes), tehran (red rey morphotypes), razavi khorasan (red neyshaboormorphotypes) and zanjan (gholyghese morphotypes). these onion morphotypes were planted inrcbd design in four replications in seed and p...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

The experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during August, 2008 to January 2009 to find out the optimum plant spacing and number of seedling per hill in relation to tillering and dry matter accumulation of transplanted rice plant. The experiment was carried out with three plant spacings (S =15 cm × 20 cm, S = 20 cm × 20 cm and S...

Low light responses of eight garden pea genotypes were investigated in the present experiment in terms of dry matter accumulation and partitioning in the plant. The light treatments consisted of (i) 100% photosynthetically active radiation (PAR) measured in the open field and (ii) 25%, (iii) 50%, (iv) 75% reduction of natural PAR obtained by using mosquito nets of variable color and mesh number...

Throughout tomato domestication, a large increase in fruit size was associated with a loss of dry matter and sugar contents. This study aims to dissect the contributions of genetic variation and the physiological processes underlying the relationships between fruit growth and the accumulation of dry matter and sugars. Fruit quality traits and physiological parameters were measured on 20 introgr...

Activities of the sucrose-cleaving enzymes, acid and neutral invertase and sucrose synthase, were measured in pods and seeds of developing snap bean (Phaseolus vulguris L.) fruits, and compared with t4C-import, elongation and dry weight accumulation. During the first 10d postanthesis, pods elongated rapidly with pod dry weight increase lagging behind by several days. The temporal patterns of ac...
