Two experiments were conducted to study the effects of water deficit stress on the germination, emergence and seedling growth of sorghum [Sorghum bicolor (L.) Moench] using Completely Randomised Block Design in four replications. Five sorghum cultivars (Jigurti, Gambella 1107, Meko, 76 T1 #23 and P9403) were evaluated under three water deficit stress treatments (0, -0.20 and -0.85 MPa) using PE...

Effect of salts (Na2SO4, Na2CO3, MgSO4, NaCl, MgCl2), soil extract and polyethylene glycol (PEG-6000) on the germination of Chenopodium glaucum L., seed was studied. Maximum germination was obtained in distilled water. Germination decreased with increase in salinity. The inhibition of germination by salt solutions was in the order of MgCl2 > Na2SO4 > Na2CO3 > NaCl > Soil extract > MgSO4. Germin...

the aim of this study was to investigate the effect of tillage methods to obtain suitable seedbed for monogerm seed. therefore, a split plot experiment based on a randomized complete block design (rcbd) with three replicatians was conducted at darab station of fars province. the main plot was seedbed prepration at two levels including fall and spring season. subplot included 1) moldboard plow a...

Due to increasing demand for medicinal and horticultural uses, the Orchidaceae is in urgent need of innovative and novel propagation techniques that address both market demand and conservation. Traditionally, restoration techniques have been centered on ex situ asymbiotic or symbiotic seed germination techniques that are not cost-effective, have limited genetic potential and often result in low...

Moisture is one essential condition for seed germination, and poor germination is very costly to growers. There is, nevertheless, little experimental evidence concerning the effects of different percentages of available moisture (5) on germination; more study of the subject is essential. Since most vegetable seeds are planted at shallow depths, there may be rapid fluctuations of soil moisture a...

The effect of accelerated aging (AA) was studied in Basil (Ociumum basilicm L.) seeds. The objective of this research was to evaluate Effect of seed ageing on germination of Basil Seeds in Roodan University in year 2012. experiment was CRD design with 3 replicate. The seeds were artificially aged at 45°C and 100% relative humidity for 24, 48, 72, and 96 hours. Results indicated germination perc...

haloxylon aphyllum is one of the most important species in sandy and saline areas in deserts, and some ecophysiology characters for viability in unfavorable condition have evaluated in this species. seed germination is the critical stages in life cycle for species survival. in this study investigated salinity and temperature stresses on percentage and velocity of germination using six salinity ...

almolookhiyeh (corchorus olitorius l.) known in the world as a valuable medicinal plant that was produced for the first time in iran in 2011. this study was aimed to quantify germination response of almolookhiyeh to temperature. for this purpose, seeds were exposed to different constant temperatures (10 ,15, 20, 25, 30, 35, 40, 45 and 50°c) in seed research lab, gorgan university of agricultura...
