A General Model for the Seasonal to Decadal Dynamics of Leaf Area
We extend the theoretical basis for understanding how climate affects ecosystem processes and provide an optimality‐based model to predict the seasonal dynamics of leaf phenology in response to climate change that could improve land‐surface models. ABSTRACT Leaf phenology, represented at the ecosystem scale by the seasonal dynamics of leaf area index ...

O objetivo deste trabalho foi avaliar a dinâmica e a heterogeneidade de dormência de gemas, e avaliar o efeito de diferentes épocas de colheita de ramos na brotação do vimeiro, no Planalto Sul Catarinense. Ramos de ano foram colhidos nos meses de abril a

Climate change is shifting flowering and animal activity times across ecosystems, potentially increasing the risk of plant–pollinator mismatches. Flower production and plant reproductive success showed varied responses to climate change depending on the ecosystem, whereas nectar rewards declined and floral scents increased or changed under warming and ...

Flowering in litchi and many subtropical fruit trees requires adequate cool temperatures. To evaluate the potential impacts of rising temperatures due to climate change on litchi fruit production, we presented an improved temperature model predicting litchi flowering based on the beta‐distribution function and used this model to estimate the likelihood

O frio acumulado em regiões de inverno ameno é insuficiente para superar a dormência de algumas cultivares de pessegueiro, como o Chiripá, sendo necessária a utilização de produtos químicos para melhorar a brotação, a floração e a produção.

In the regions with mild winters, usually the chilling requirements for bud dormancy release of grapevines are not fulfilled, and only the highly toxic products CaCN2 (calcium cyanamide) and H2CN2 (hydrogen cyanamide) are recommended in conventional ...

CONVERSION OF BOUND TO FREE WATER IN ENDODORMANT APPLE BUDS
Proton Density and T2 maps were created throughout the dormant season in `Anna' and Northern Spy′ apple cultlvars. The percentige of oixels with 15-25 ms T2 time increased from 30% in both cultlvars at the beginning of dormancy to 80 and 72% respectively, by the end of dormancy. The conversion in `Anna' was rapid and in `Northern spy was slow.

Adaptation to seasonality and the winter freeze
Flowering plants initially diversified during the Mesozoic era at least 140 million years ago in regions of the world where temperate seasonal environments were not encountered.
