Na SO induced regulation of some key morpho-physiological characteristics in Sorghum were 2 4 examined to investigate the effect of Na SO on germination and morphology of Sorghum that was conducted 2 4 at Botany Department University of Gujrat. The variety used in this experiment was SSG-77. Plants were subjected for 30 days to sand culture that were salinized with four salt levels [T (control)...

24-Epibrassinolide belongs to the brassinosteroid family of plant hormones, and carbenoxolone is a synthetic analogue of glycyrrhizic acid that inhibits enzymes important in steroid and prostaglandin action in animals. The e€ect of these compounds on root nodulation, root growth and shoot growth of Glycine max (L.) Merr. cv. Tracy M was examined. Epibrassinolide reduced total nodulation, plant ...

In order to explore the mechanism of delayed and uneven germination in sharp tooth oak (Quercus aliena var. acuteserrata) (STO), mechanical scarification techniques were used to study STO root and shoot germination and growth. The techniques used were: removing cup scar (RS), removing the pericarp (RP), and cutting off 1/2 (HC) and 2/3 (TC) cotyledons. Germination percentage and root and shoot ...

Acclimation to changing light conditions plays a crucial role in determining the competitive capability of tree species. There is currently limited information about acclimation to natural light gradient and its effect on shoot structure and biomass in Taxus species. We examined the acclimation of the leaf and shoot axis morphology, structure and biomass allocation of Taxus yunnanensis and T. c...

in order to study, the effects of drought stress on germination and seedling growth of chickpea genotypes, experiments were carried out on two susceptible genotypes (mcc68, mcc448) and two resistant genotypes (mcc392, mcc877). in the first experiment the seeds were sown under different levels of drought stress (0,-0.4,-0.8,-1.2mpa) in 25◦c at the growth chamber with 4 replication. the results s...

abstract growth retardants are new chemical organic compounds that increase period of flowering, leave chlorophyll, lateral shoot number, flower number and decrease vegetative growth. they also increase dry, cold and heat tolerance. paclobutrazol and cycocel are examples of these compounds. this study was conducted to evaluate the effect of paclobutrazol and cycocel on some quantitative and qua...

We developed an equation for estimating Arundo donax shoot dry weight from shoot length. The equation, shoot dry weight (g) = 14.254 (standard error = 0.275) shoot height (m), was as effective at explaining a high proportion of total variation in shoot dry weight (R = 0.90) as more complicated equations containing additional morphometric parameters. Tested against two independent datasets, the ...

BACKGROUNDS AND AIMS Shoot demography affects the growth of the tree crown and the number of leaves on a tree. Masting may cause inter-annual and spatial variation in shoot demography of mature trees, which may in turn affect the resource budget of the tree. The aim of this study was to evaluate the effect of masting on the temporal and spatial variations in shoot demography of mature Betula gr...
