effects of morph physiological characteristics on yield and yield components of corn grain were investigated. an experiment was conducted in the experimental field of abourayhan campus, university of tehran. the experimental design was a block in split plot arrangement with four replications. planting dates were as main factor with three levels (4th, 14th and 25th june) and four varieties (sing...

Grassland prairies of western Oregon and Washington are among the most endangered ecosystems in the United States. Active management and restoration are needed to promote biodiversity in the region. To support plant production for use in habitat restoration, we developed germination protocols for greenhouse propagation of Iris tenax (Oregon iris). Dormancy was most effectively overcome (63% ger...

We investigated the influence of different conditions (light composition and plant growth regulators (PGRs) in culture media) on morphophysiological parameters Stevia rebaudiana Bertoni vitro vivo. Both PGRs light spectra applied were found to significantly affect morphogenesis. During micropropagation stage S. rebaudiana, optimal growth, with a multiplication coefficient 15, was obtained an MS...

Abstract. The use of biofertilizers based on plant growth promoting (PGP) bacteria is a promising direction in agri-biotechnology. purpose was to evaluate the PGP-attributes Bacillus sp. and reveal morphophysiological features rapeseed (Brassica napus L.) when inoculated with these rhizobacteria. Methods. ability strain TO15c isolated from rhizosphere Taraxacum officinale Zack's nitrogen-free m...

earliness and drought escape are as a primary strategy for plant adaptation in regions that plants are subjected to terminal drought stress. plants react to drought through morphological changes and alteration in physiological behavior. accordingly, two separate experiments to assess the response of yield and morphophysiological characteristics of earliness chickpea genotypes to drought stress ...

On the basis of previously validated biological concepts, a model of postnatal growth in livestock is proposed. It postulates the existence of two leading processes, cell proliferation in growth plates of bones and nuclei multiplication in skeletal muscle tissue, and surmises that the basic kinetic parameters of RNA and protein metabolism in cross-striated muscles remain steady (relatively cons...

Abstract Global climate change induced environmental stress such as salinity significantly impact growth and crop productivity. Red amaranth ( Amaranthus tricolor L.) is a vegetable commodity that has high nutritional value, but its productivity will decrease when grown in saline area. Seed priming one of the pre-planting treatment techniques used to increase plant under unfavourable conditions...
