this study was carried out to determine some mechanical properties of barley seed including deformation, rapture force, rapture energy and toughness as a function of moisture content (10.5%, 12.5%, 14.5% , 16.5%, db), loading rate (5, 15, 25, 35 mm.min-1) and grain size (small, medium, large). tests were performed at 7 replications by the means of a factorial base plot experiment. the results s...

the efficiency of oil extraction from oil seeds is affected by seed harvesting time, drying methods, seed storage conditions and finally the means of seed transportation to the factory. to determine the grain moisture content at harvest  and its effect on seed while on drying trails, (employing different canola dryers), a study was conducted in mazandaran province in 2009. a factorial complete ...

Almost all properties of grains and seeds depend on moisture content. One of these properties is dielectric constant. Therefore capacitive sensor is used in precision agriculture widely. In this paper, a cylindrical capacitor was used to measure dielectric constant of seed. By measuring the dielectric constant, the moisture content of grains may be predicted. Change in dielectric constant of co...

Pollination and fertilization of canola flowers are the main factors of canola seed production. In order to study the effects of insect pollinators on seed quantity and quality of three chosen cultivars of canola, namly, S.L.M., Okapi and Talaye, a split plot experiment in a complete randomized block design with four replications was carried out in Isfahan region. Main plots consisted of canola...

Influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. High germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...

in this study, moisture dependent physical, mechanical and nutritional properties of sesame seed were evaluated. in the moisture range of 4.54–19.27% (d.b.), seed length, width, thickness, arithmetic mean diameter and geometric mean diameter increased linearly from 2.93 to 3.01 mm, 1.74 to 1.78 mm, 0.78 to 0.86 mm, 1.81 to 1.88 mm and 1.58 to 1.66 mm respectively with increase in moisture conte...

Investigations of recalcitrant, or desiccation-sensitive, seeds have as yet failed to identify the causes of this phenomenon. Experiments with Guarea guidonia (L.) Sleumer (American muskwood) were initiated to determine the effects of desiccation on the physiology and biochemistry of the seeds of this tropical tree species. Seeds were air-dried at room temperature for 7 days. At intervals, germ...

Seeds of the recalcitrant species lychee (Litchi chinénsis Sonn.) and longan (Dimocarpus longan Lour.) were stored near 100% relative humidity at 8 to 10C in air, 80% nitrous oxide (N2O) plus 20% oxygen, or 100% nitrous oxide. The combination of anesthetic and oxygen extended storage longevity of both species. Seeds stored in 100% N2O lost terminability at the same rate as those stored in air. ...
