The article presents the results of analysis cultivar composition Iris × hybrida hort. collection Nikitsky Botanical Gardens according to bloom season and color classification. As a result phenological observations, average long-term dates «beginning flowering» phase in conditions South Coast Crimea were determined for all cultivars. definition studied cultivars within garden groups into early ...

Thermal conditions at the beginning of the year determine the timing of pollen seasons of early flowering trees. The aims of this study were to quantify the relationship between the tree pollen season start dates and the thermal conditions just before the beginning of the season and to construct models predicting the start of the pollen season in a given year. The study was performed in Krakow ...

An experiment was conducted during the season from March 2018 – June at Horticulture farm of Lovely Professional University, Phagwara (Punjab). The three replications experimental trial used a randomized block design. Eleven alternative approaches were in trial. Based on findings trial, it possible to concluded that treatment T8 GA3 (100ppm) had significant impact growth and phenological parame...

Modeling pollination ecosystem services requires a spatially explicit, process-based approach because they depend on both the behavioral responses of pollinators to the amount and spatial arrangement of habitat and on the within- and between-season dynamics of pollinator populations in response to land use. We describe a novel pollinator model predicting flower visitation rates by wild central-...

BACKGROUND AND AIMS The distribution and differentiation times of flowers in monoecious wind-pollinated plants are fundamental for the understanding of their mating patterns and evolution. Two closely related South American Nothofagus species were compared with regard to the differentiation times and positions of staminate and pistillate flowers along their parent growth units (GUs) by quantita...

Phenological patterns have a great influence on community ecology. I have quantified fruit abundance using fruit traps, phenological transects, and observations on marked trees of selected species. All methods showed the main peaks of fleshy fruit production between the dry period and the middle of the rainy season. Wind, water, and mechanically dispersed seeds showed a peak of production at th...

There is demand for early-flowering cannabis ( Cannabis sativa ) cultivars to hasten harvest and avoid late-season detrimental weather conditions. A field study greenhouse studies were conducted evaluate the effect of gene dosage at autoflowering locus on flowering timing diploid triploid hybrids between photoperiod-sensitive parents. Autoflowering × all photoperiod sensitive, but their critica...

difficult to prove cause and effect for maturity differences being responsible for any variation in response Potassium deficiency in cotton (Gossypium hirsutum L.) depresses among genotypes to K. Theoretically, differences in root yield by decreasing late season growth and is reportedly more harmful to early maturing cotton genotypes. Research objectives were to detersystem size or effectivenes...

in order to study the effect of drought stress and harvesting stages on quantitative and qualitative yields of coriander (coriandrum sativum l.) this experiment was conducted on split plot based on a randomized completely block design with 3 replications in torbat-e heydariyeh university, iran, during growing season of 2010-2011. treatments were drought stress (in three levels no stress: contro...
