in order to study effect of seed weight on germination and growth of wheat seedling, an experiment in seed technology laboratory of aboureihan paradise university of tehran in 2005 has been done. in this experiment, at first stage, the seeds separated by longitude step, latitude step and set frequency parameters of gravity separator set. in second stage, 10 treatments of 1000 seed weight entere...

An experiment was conducted to evaluate and compare the seed extraction methods on physiological quality of eggplant seed in Seed Technology Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University during 2012-2013 growing season. Full ripen standard size fruits (60 DAA) of eggplant var. BARI begun-5 (round shape) and BARI begun-8 (long shape) were harvested and kept in ambient c...

A laboratory study was conducted to evaluate the benefits (if any) associated with the incorporation of polyamines in the priming media for hybrid sunflower achene priming. Achenes were subjected to hydropriming for 24 h and in the solutions containing 10 mg L spermidine and putrescine for 24 h. All the achene priming treatments resulted in improved germination and early seedling growth. Primin...

The effect of salt and drought stress at the water potentials of-2, -4,-6and -8 bars induced by NaCl and PEG 6000 (Polyethylene glycol 6000) each, on germination and early seedling growth, were investigated for two varieties (PU-19 and Type-9). Electrical conductivity (EC) value of the NaCl solutions were 4.5, 8.8, 12.7 and 16.3 dS m(-1). Germination percentage, root and shoot length, and seedl...

A pot culture experiment was conducted to study the effect of biomass power plant effluent on seed germination, seedling growth and chlorophyll content of green gram (variety LGG 460) have been estimated at different effluent concentrations and time intervals. The effluent is alkaline in nature (pH 8.5), odorless, and comprises of heavy metals such as Cr (0.071 mg l(-1)), Cu (0.014 mg l(-1)), M...

The experiment was performed to study the seed germination and seedling growth in wheat under the influence of different concentrations of copper. The germination %, plumule and radicle length, and number of lateral roots decreased with increase in copper concentration (5, 25, 50 and 100 mgl(-1)). Total chlorophyll contents declined on 14th day from 1.605 of control to 1.581, 1.242, 1.275 and 1...

In order to determine the impact of thermo priming on germination of soybean seeds, an experiment was conducted as a completely randomized design with three replications. The factors of studied included different time thermo priming (control, 5 and 10 minutes) through the placing seeds were exposed to oven. The results showed that the effect of thermo priming was significant on germination perc...
