environmental stresses especially drought stress affect on the different aspects of plant growth and cause decrease and delay in germination, decrease of aerial parts growth and decrease in dry matter production. in order to study the effect of drought stress on germination and seedling growth of roselle (hibiscus sabdarifa) medicinal plant, this experiment was conducted in a randomized complet...
In order to study the effect of different levels of salinity stress on germination indices and early growth of Trigonella foenum-greacum L., an experiment was conducted in agronomy laboratory of Faculty of Agricultural at the University of Guilan in 2012. The experiment was arranged base on completely randomized design with four replications. The used treatments were different levels of sa...
A laboratory research carried out to evaluate the effect of drought stress on germination characteristics in two 'Indian' and 'Isfahanian' populations of Fenugreek. This experiment performed in a factorial experiment based on a completely randomized design with three replicates. Four levels of drought stress applied by using polyethylene glycol 6000. Percentage of germination, germination rate,...
background and objectives: seed vigour is the resultant of a broad range of physiological processes which have genetic background. the study of genetic variation, play an important role in enhancing the ability of breeders in selection and breeding operation. this study aimed to evaluate rice genotypes with the physiological and morphological characteristics related to seed vigour and grouping ...
Extended Abstract Introduction: Drought stress, as abiotic and multidimensional stress, has severe effects on plant growth. One of the new approaches in the management of drought stress is the use of nanoparticles. Nanoparticles infilterate the seeds and increase nutrient and water uptake and ultimately, improve germination. The present research was conducted to evaluate the effects of titaniu...
to evaluate germination and seedling growth of safflower an experiment carried out as factorial with two factor; temperature (5, 15, and 25 °c) and salinity of sodium chloride (0, 5, 10, and 15 ds/m) based on randomized complete block design with four replications, in dept. of horticulture of urmia university. results of different concentration sodium chloride on germination and seedling growth...
To investigate the role of seed size on maize germination characteristics, an experiment was conducted in 2014 in the Laboratory of Registration and Certification of Seeds and Plants, Khuzestan Branch. Treatments included three levels of seed size (control (mixed), large and small) and hybrids at three levels (KSC704, Karun and Mobin). The results of these experiments showed that the hybrid had...
The first experiment was performed to evaluate the effect of vermicompost extract (20, 40, 60, 80, 100%) on seed germination and seedling growth of Plantago psyllium. In second experiment, the effect of solid vermicompost with 4 levels (0, 25, 50, 75) on the emergence and subsequent growth of plantlets was investigated. The 20 and 40% increased germination capacity, germination index, and lengt...
Drought significantly reduces yield of many crop plants including wheat in the world. Identification of wheat genotypes that can thrive on limited water is vital to boost the wheat production of rainfed areas. Forty wheat genotypes were screened for drought tolerance using 0, 7.5, 15 and 22.5% Polyethylene Ethylene Glycol 6000 solutions at PMAS Arid Agriculture University, Rawalpindi, Pakistan ...
The objective of this research was to evaluate the effect of salicylic acid and gibberellic acid on germination characteristics and changes of proline, protein and catalase activity of Brassica napus seedlings under Cu(SO4) stress. The experimental design was factorial with complete randomized design as a base design with 3 replications. The first factor was 4 levels of Cu(SO4) stress (0, 10, 2...
