dormancy breaking of field maple (acer campestre l.) seed, by gibberllic acid (ga3) at 0, 250, 500 and 1000 ppm in 24 and 48 hours and stratification treatments in moist sand under warm (18-20 °c) and cold (2-4°c) conditions were investigated. effects of ga3 and stratification and their interaction on germination percent (gp) and germination speed (gs) were significant. the highest gp occurred ...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Ferula ovina is one of forage species of Isfahan and Chaharmahal va Bakhtiari whose natural spreads are under destruction. Finding information about its seed dormancy, effective factors in the dormancy breaking and also about optimal conditions of seed germination is necessary for recovery of this plant spreads. To actieve that goal, two factorial experiments were performed in completely random...
seeds of most herbs such as medicinal plant alyssum bracteatum are known to have a dormancy period in a natural condition. therefore, the identification of factors affecting seed dormancy and germination in order to create optimum conditions for large-scale cultivation of medicinal plants is necessary. the survey was conducted at the research laboratory of biology, university of lorestan in aut...
