eight strawberry cultivars (paros, queen elisa, pajaro, camarosa, gaviota, selva, mrak and kurdistan as local cultivar) were evaluated to select the best cultivar based on quantitative yield production in kurdistan province condition. an experiment was performed in a randomized complete block design with three replications during 2008- 2010 in grizeh research station (sanandaj). eleven morpholo...
A new system has been developed and calibrated to measure the charactristics and distribution of skylight polarization. With a series of measurements obtained, we verified that the distribution of degree and angle of skylight polarization accords well with the predictions of Rayleigh scattering. The differences of the characteristics and distribution of skylight polarization across the principa...
The timing of phenological events, such as leaf-out and flowering, strongly influence plant success and their study is vital to understanding how plants will respond to climate change. Phenological research, however, is often limited by the temporal, geographic, or phylogenetic scope of available data. Hundreds of millions of plant specimens in herbaria worldwide offer a potential solution to t...
Test measurements with 241Am-α-particles, 12C, 20Ne, 58Ni, 208Pb and 238U projectiles are performed. It is shown that the most important charactristics of heavy-ion diamond detectors are described by the shaping parameters of the detectors single pulse. Distributions of rise and decay times of the signals as well as of the associated charge amplitudes are discussed. An intrinsic time resolution...
Climate change-induced shifts in phenology have important demographic consequences, and are frequently used to assess species' sensitivity to climate change. Therefore, developing accurate phenological predictions is an important step in modeling species' responses to climate change. The ability of such phenological models to predict effects at larger spatial and temporal scales has rarely been...
