Statistical evaluation of bud development theories: application to bud burst of Betula pendula leaves [PDF]
Resampling methods were used to evaluate models based on alternative bud development theories applied to Betula pendula Roth data. Statistical testing based on the bootstrap method showed that the mean square errors (MSE) of the predicted bud-burst dates of two models, in which the start of ontogenetic development depended on dormancy development only,

Geographical Variation in Bud-burst Timing of Zelkova serrata Provenances [PDF]
This study was conducted to examine the geographic variation of bud phenology of Zelkova serrata provenances. Data were collected from Gangneung, Yilmsil, Hwaseong and Jinju plantations which were parts of the 6 provenance trials established by Korea Forest Research Institute in 2009. The 16 provenances were included in these trials.

Predicting the Date of Bud Burst in Grapevines
It was possible to forecast the date of bud burst under South African winter temperatures (Region III) using the Pouget-formulae and principles, and to establish a scale of bud burst for cultivars grown in South Africa. The sum of daily temperature effects was higher under the warmer South African conditions which resulted in changes in the formulae ...

Tree growth and reproduction results from the balance between internal and environmental factors. Knowledge is lacking on this balance in evergreen fruit trees characterised by a permanent contrasted light environment within the crown.

Phenological observation of white grape varieties in the grape growing area of Grocka [PDF]
Phenological stages of white wine varieties grown in the "Radmilovac" collection vineyard were recorded during a three- year period. The included stages were: time of bud burst - shoot growth, flowering, véraison and full ripening.

Sexual pheromone modulates the frequency of cytosolic Ca2+ bursts in Saccharomyces cerevisiae [PDF]
Transient and highly regulated elevations of cytosolic Ca2+ control a variety of cellular processes. Bulk measurements using radioactive Ca2+ and the luminescent sensor aequorin have shown that in response to pheromone, budding yeast cells experience a ...

Early phenology and growth trait variation in closely related European pine species [PDF]
Closely related taxa occupying different environments are valuable systems for studying evolution. In this study, we examined differences in early phenology (bud set, bud burst) and early growth in a common garden trial of closely related pine species ...
