To study the effect of production region and seed size on germination indices and heterotrophic growth components of peanut seedling, a study was performed in three peanut fields in Astaneh Ashrafieh and Agronomy Laboratory of Rasht Islamic Azad University from 2010 to 2012. This research was carried out using the standard germination, cold and accelerated aging tests. Tests were performed usin...
DOR: 98.1000/2383-1251.1398.6.115.11.1.1575.1610 Extended Abstract Introduction: In recent years, Japanese morning glory has been recognized as a new weed in some soybean cultivation areas in the Province of Golestan. Japanese morning glory, an annual herbaceous plant, belongs to Convolvulaceae family. Germination is the first step in the competitiveness of a weed in an ecological niche. ...
Effects of silver nanoparticles on plant growth parameters such as Root length, fresh weight, Dry weight, Speed of germination and % Germination contents of economic important pulses, Fenugreek (Trigonella foenum-graecum); was probed in the present research. The study was carried out in a randomized block design with three replications. Five levels of silver nanoparticles (0, 10, 20, 30 and 40 ...
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...
response of seed germination of a crop to different environmental conditions is one of the most important determination factors to indicate its ability in competition with weeds. in order to evaluate the effects of water depth and temperature on the germination of different varieties of rice and barnyard grass, an experiment was conducted in the seed laboratory, faculty of agriculture, ferdowsi...
This study investigates the effect of sonic stimulation on Bacillus endospore germination. Germinating endospores in a microtiter plate were exposed to audible sound wave generated by an array of piezoelectric transducers. In situ germination kinetics was measured by terbium-dipicolinate fluorescence assay, optical density measurement and phase contrast microscopy. Fluorescence results revealed...
in order to study the effects of on-farm seed priming and sowing date on germination percentage, germination speed, and some growth indices of three soybean cultivars, a field experiment was carried out in three replications using a split plot factorial in a randomized complete block design. main plots were representative of two sowing date (5th and 21th of may), while subplots included combina...
In order to investigate different treatment effects on germination in Gundelia tournefortii, three factorial experiments were carried out in the completely randomized design with three replications. The first factor was stratification at 4oC in three levels including 0, 3 and 6 weeks, the second factor was mechanical scarification in two levels including seeds with/without scarification and the...
“Quina” (Strychnos pseudoquina A. St. Hil) is a medicinal plant species from the Brazilian Cerrado. As its seeds show dormancy, they were subjected to the treatments precooling at 5oC during 7 days, pre-heating at 40oC during 7 days, pre-soaking in sulfuric acid PA during 5 and 15 min, pre-soaking in boiling water during 5 and 15 min, pre-soaking in 100 and 200 ppm gibberellic acid during 48 h,...
