Temperate woody perennials survive to low temperatures in winter entering a dormant stage. Dormancy is not just a survival strategy, since chilling accumulation is required for proper flowering and arbitrates species adaptation to different latitudes. In spite of the fact that chilling requirements have been known for two centuries, the biological basis behind remain elusive. Since chilling acc...

Carnation crop in Colombia is one of the main income generating activities Colombian floriculture. However, growth dynamics and its relationship with thermal time are unknown. For this reason, objective research was to determine development carnation (Dianthus caryophyllus L.) cv. ‘Moon Light’ when grown a greenhouse Bogotá savanna. This developed based on phenological stages accumulation Growi...

Previous reports from laboratory-controlled experiments and models considered that a shorter reproductive period could be the main reason for wheat yield reduction in the warmer world. However, this conclusion needs to be proved carefully by field-scale experiments. In this study, a field-scale continuous open-warming experiment was conducted to quantify the adjustment of winter wheat growth an...

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...

Phenological metrics extracted from satellite data (phenometrics) have been increasingly used to access timely, spatially explicit information on crop phenology, but have rarely been calibrated and validated with field observations. In this study, we developed a calibration procedure to make phenometrics more comparable to ground-based phenological stages by optimising the settings of Best Inde...

in order to evaluate phenological characteristics, yield and yield components of 18 cold tolerant lentil genotypes in fall planting under supplementary irrigation, an experiment was carried out based on randomized complete block design in 2006-2007 at research farm of college of agriculture, ferdowsi university of mashhad. irrigation was performed three times: immediately after sowing, 20 days ...

Consequences of climate change on tree phenology are readily observable, but little is known about the variations in phenological sensitivity to drought between populations within a species. In this study, we compare the phenological sensitivity to temperature and water availability in Abies pinsapo Boiss., a drought-sensitive Mediterranean fir, across its altitudinal distribution gradient. Twi...

Uncrewed aerial systems (UASs) provide high temporal and spatial resolution information for crop health monitoring informed management decisions to improve yields. However, traditional in-season yield prediction methodologies are often inconsistent inaccurate due variations in soil types environmental factors. This study aimed identify the best phenological stage vegetation index (VI) estimatin...

the time of duration of plant developmental stages could have an effect on crop yield and adaptation in a specific environment. the aim of this study was to evaluate the phenological behavior in a wide range of wheat cultivars and their relation with adaptation and potential of crop production in a specific climate (semi-arid and cold). by using a simple lattice design with three replications i...
