Effect of bulb size on quality seed production of onion in Bangladesh
A study was conducted in the experimental farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, which is situated at 24.040 N latitude and 90.40 E longitudes with an elevation of 8.4 meter from the sea level and in the 28th Agro ecological Zone (AEZ) during the year 2011 to 2012. The purpose of […]
Impact of climate on seed morphology and plant growth of Caesalpinia bonduc L. in West Africa
Caesalpinia bonduc L. is an important medicinal plant threatened by overexploitation. In the present study, the impact of climate on seed morphology, germination capacity, seedling and plant growth of C. bonduc were evaluated. A total of 2000 seeds were collected in Sudanian and Guinean climate zones of Africa and their length, width, thickness, weight and […]
Performance of some soybean Glycine max (L.) Merrill. cultivars under salinity stress to germination characters
In order to examine the effect of osmotic stress on six soybean cultivars i.e. Giza 21, Giza 22, Giza 35, Giza 82, Giza 83 and Giza 111 at germination stage to salinity stress i.e. 0, 3, 6, 9, 12 and 15 dSm-1 NaCl and to confirm seedling germination to examine a range of genetic variability […]
The effects of priming by folic acid and hydrogen peroxide on morpho-physiological traits in cannabis seeds (Cannabis sativa L.)
Effect of various folic acid and hydrogen peroxide concentration on some traits of cannabis performed based on randomized complete blocks design in research green house of Islamic Azad University of Mahabad, Iran. Experiments treatments were levels of folic acid (0,5,10,15,20,25,27Mm), hydrogen peroxide (0,7.5,15,22.5,30,37.5,40 Mm) and control (non-primed) which replicated 4 in 24 and 6 h […]
Effects of physical treatments on germination and stand establishment of sunflower (Helianthus annuus L. var. Hyson) under laboratory condition
Seed priming has been reported to enhance growth of plants. To evaluate the effect of some physical seed priming materials (ultrasonic, gamma, beta and laser irradiation, magnetic field and hydro-priming) on seed germination and growth of sunflower a laboratory experiment was conducted at Islamic Azad University of Tabriz branch, using completely randomized design, with three […]
Differential allelopathic effect of nine Haplophyllum tuberculatum growth forms through germination bioassay
The main objective of the present study was to analyze and discriminate among nine growth forms (GF) of Haplophyllum tuberculatum collected from six natural sites along the Mediterranean coastal desert of Egypt byapplying the phenomenon of allelopathy as a chemical marker. H. tuberculatum aqueous extracts (HTAE) were tested on germination efficiency and growth parameters of […]
Effects of allelochemical extracts from medicinal plants on physiological and biochemical mechanisms of maize (Zea mays L.) seedlings
Aqueous extract of Ricinus communis and Lantana camara contains substances that have allelopathic potential on maize (Zea mays L.). The present study showed that different concentrations of the water soluble leaf extracts of R. communis and L. camara inhibit the germination and growth of maize. These extracts also affect activity of some enzymes. Leaf aqueous […]
Seed priming affected physiology and grain yield of chickpea under salt stress
In order to study the effect of priming and salinity on seed germination, physiological characteristics and grain yield of chickpea, an experiment was carried out under hydroponic condition. Results showed that germination percentage and rate significantly reduced under salt stress. KNO3 was proper trait than that of hydro-priming to improving germination rate. Leaf area index […]
Changes in seed vigour of ragon’s head (Lallemantia iberica Fish. et Mey.) under irrigation and plant density treatments
A field experiment was conducted in 2012 to investigate the effects of different irrigation treatments and plant density on seed vigour of Dragon’s head (Lallemantia iberica Fish. et Mey.). The experiment was arranged as split plot based on randomized complete block design with four replications. Irrigation treatments (I1, I2, I3, I4 and I5: irrigation after […]
Physiological impact of sodium azide on Helianthus annus seedlings
The present study was carried out to demonstrate the effect of sodium azide on Helianthus annuus var.“Giza 53” at the green house of Botany Department, Faculty of Science, Tanta University, Egypt. Seeds were soaked in different concentrations of sodium azide (0.5, 1.0 and 2.0 mM) for different time intervals (30, 60, 90, 120 and 150 […]
