The timing of the fruit-set stage (i.e., start and end of fruit set) is crucial in a plant's life cycle, but its response to temperature change is still unclear. We investigated the timing of seven phenological events, including fruit-set dates during 3 yr for six alpine plants transplanted to warmer (approximately +3.5°C in soils) and cooler (approximately -3.5°C in soils) locations along an a...
Rosemary (Rosmarinus officinalis L.) is an important medicinal plant that contained a wide range of secondary metabolites such as rosmarinic acid. In this study, essential oil content and composition and rosmarinc acid were determined at three phenological stages (before flowering, full flowering and fruit set stages). Hydro distillation method was used for essential oil extraction and GC and ...
In this study, aerial parts of Lippia citriodora Kunth were harvested at three phenological stages (i.e. vegetative, full flowering and fruit set). The essential oil isolated by hydro distillation for 3 h using a Clevenger-type apparatus and the oil was analyzed by GC and GC-MS. The yields of oils (w/w%) in different stages was in the order of: full flowering (0.9%), vegetative (0.48%) and frui...

Winter dormancy is a well known mechanism adopted by temperate plants, to mitigate the chilling temperature of winters. However, acquisition of sufficient chilling during winter dormancy ensures the normal phenological traits in subsequent growing period. Thus, low temperature appears to play crucial roles in growth and development of temperate plants. Apple, being an important temperate fruit ...
To date, phenological research has provided evidence that climate warming is impacting both animals and plants, evidenced by the altered timing of phenophases. Much of the evidence supporting these findings has been provided by analysis of historic records and present-day fieldwork; herbaria have been identified recently as an alternative source of phenological data. Here, we used Rubus specime...
BACKGROUND AND AIMS Herbaceous-shrubby communities in the Gran Sabana (Great Savanna) Plateau of Venezuela grow under non-zonal conditions. We speculated that this would produce specific patterns of reproductive phenology within these different soil-climate-vegetation associations. Specifically, we tested the hypothesis that the reproductive phenology patterns of four herbaceous-shrubby communi...
Regulated deficit irrigation (RDI) is commonly used during different phenological stages of fruit growth and development in almond trees to reduce the amount of irrigation water applied without or with only very small reductions in yield. Therefore, to study the effects of deficit and cutoff irrigation during different phenological stages of fruit growth and development in almond cv. “Mamaei” p...
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...
The experiment was carried out to study pomochemical properties of twenty superior genotypes of apricot (Prunusarmeniaca L) during two consecutive growing seasons (2013-2014) in the Khalkhal valley, south of Ardabil province (Iran). Physical parameters (weight, flesh, skin and color) and chemical parameters (total soluble solids content and acidity) were evaluated using Principal Component Ana...
