in order to evaluate the effects of methanol on germination percentage, germination speed index, plumule and radicle length, plumule and radicle dry weigh, vigor index and consumed endosperm of bean in condition of water deficit, a factorial experiment done based on completely randomized design with three replications. the first factor was different levels of methanol included 0 (control), 5, 1...

To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...

the effective factors of forward speed, cylinder rotation, and clearance between a combine’s cylinder and concave on wheat kernel breakage and seed germination were studied in karaj area using a 955 model john dear combine. this study was conducted on three levels of adjustment for each of the variables, 1.2, 1.8 and 2.5 km/hr for forward speed, 800, 900, 1000 rpm for cylinder rotation as well ...

the effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...

Several pre-germination treatments were given to Cyclamen persicum Mill. seed with the objective of improving germination percentage, speed, and uniformity. Soaking seed in water and in gibberellic acid improved germination speed, but the latter reduced survival. Etridiozole, benomyl, thiram, and sodium hypochlorite treatments did not reduce or delay germination as has been reported elsewhere, ...

the germination characteristics and seedling growth of 25 rapeseed cultivars under six levels of salt (naci) stresses including 0, 3, 6, 9, 12 and 15 ds/m were studied. the germination percentage of the rapeseed cultivars did not decrease significantly with increasing salt levels up to 12 ds/m. however, the required time for germination increased with increasing the salt percentage in the growt...
