The variability of essential oil characteristics in different phenological stages of Clinopodium pulegium from its natural habitat (Svrljiški Timok gorge, Serbia) and from cultivated plants (Niš, Serbia) was determined. The essential oils were obtained from aerial parts of the plants by hydrodistillation and analyzed by GC-MS. These are the first data on the essential oil characteristics of pla...
A total of 25 advanced rapeseed (Brassica napus L.) varieties were evaluated under cold weather conditions using Randomized Complete Block design (RCBD) with four replications in Dr. Nakhjavani Agricultural Research Station, 35 km North-East of Urmia the capital of West Azerbaijan province in 2000-2001. The results showed significant differences among the varieties (P ≥ 0.01) for all the pheno...
Range forage of Vicia variabilis, Astragalus spp., Medicago sativa, Prangos uloptera and Sanguisorba minor was sampled during three phenological stages from the controlled rangeland stations in Chaharmahal and Bakhtiari province, Iran. Samples were analyzed for the determination of Crude Protein (CP%), Ether Extract (EE), Crude Fiber (CF), total Ash, Neutral Detergent Fiber (NDF), Acid Detergen...

Astragalus fridae Rech. F. is a native and endemic species in Iran. Considering the circumstances of this species in the country and the world and the importance of conservation of genetic resources, the awareness of A. fridae forage quality seems necessary. For this purpose, forage samples of A. fridae were taken at four phenological stages including vegetative growth, flowering, seed setting ...
Trait differences between invasive and native species are believed to be closely related to whether the former are successful. However, few studies have measured trait differences between invasive and native species directly under field conditions or during long term experiments. We examined the phenological pattern, plant height and biomass accumulation and allocation of Crofton weed (Eupatori...
We are now reaching the stage at which specific genetic factors with known physiological effects can be tied directly and quantitatively to variation in phenology. With such a mechanistic understanding, scientists can better predict phenological responses to novel seasonal climates. Using the widespread model species Arabidopsis thaliana, we explore how variation in different genetic pathways c...
The objectives of this work were to determine the heliotropic movements of the upper trifoliates for two soybean cultivars, BR 16 and Embrapa 48, during a daily cycle, in three phenological stages and two water regimes, and to estimate the impact of irrigation and daily leaflet movements on agronomic characteristics and grain yield. Heliotropic movements were studied in three phenological stage...
