120 RESPIRATORY CHANGES IN APPLE VEGETATIVE BUDS AND INTERNODES DURING BUDBREAK [PDF]

open access: yesHortScience, 1994
One-year-old potted `Jonagold' apple trees on M. 9 EMLA rootstock were chilled in a cold room at 5C for 1320, 3288 or 4464 hours. They were then placed in a 22C greenhouse for forcing. Rate of dark respiration of buds and internodes was measured in vivo using the LICOR LI 6200 portable photosynthesis system.

Shifts in leaf color during ontogeny do not affect herbivory in the tropical tree Lecythis pisonis (Lecythidaceae)

open access: yesPlant Species Biology, Volume 40, Issue 5, Page 500-509, September 2025.
Leaf color has been rarely evaluated as an important trait influencing herbivory levels in tropical plant species. Cannonball trees (Lecythis pisonis) present pink young leaves that are smaller, softer and with less chlorophyll that progressively turn into green as the season progresses. When all three leaf colors are present in the plants, there is no

Silver Thiosulfate Application Influences Rooting and Budbreak of `Royalty' Rose Cuttings [PDF]

open access: yesHortScience, 1991
The effects of silver thiosulfate (STS) on stored and freshly made cuttings of `Royalty' rose (Rosa hybrids) were examined in relation to rooting and subsequent budbreak. STS pretreatment at 0.5 mm during storage stimulated budbreak but decreased the percentage of cuttings that rooted and the number of roots. IBA at 4.9 to 9.8 mm inhibited budbreak but

Evaluation of vegetative phenological stages in a spruce monoculture depending on parameters of the environment

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
Vegetative phenological stages were evaluated in a spruce monoculture of the third age class in the region of the Drahanská vrchovina Upland. Methods of the ČHMÚ (Czech Hydro-Meteorological Office) were used. Temperature requirements of Norway spruce for

Heat requeriment for inducing budbreaking in different apple cultivars

open access: yes, 2021
The heat requirements for bud burst of six apple cultivars were evaluated. Shoots with 20 to 25cmlength were submitted to 1,150 cold units. After this treatment, shoots were divided in single bud cuttings and treated at different temperatures (5, 10, 15, 20 and 25oC).

Performance of ‘Maxi Gala’ apple trees as affected by budbreak promoters, in São Joaquim-SC

open access: yesRevista Brasileira de Fruticultura, 2018
The application of rest breaking agents to compensate the lack of chilling is a common practice in apple orchards in Southern Brazil. However, its necessity in areas of greater chilling accumulation has been questioned over the years.

Seleção de genótipos de pessegueiro F1 com baixa necessidade de frio hibernal Selection of F1 peach genotypes with low chilling requirements

open access: yesRevista Brasileira de Fruticultura, 2009
A baixa necessidade de frio é característica fundamental para que se possa cultivar economicamente o pessegueiro em condições de clima subtropical, devendo ser este, portanto, o principal objetivo dos programas de melhoramento nestas regiões.

Mild temperatures on bud breaking dormancy in peaches Temperaturas amenas na superação da dormência de pessegueiros

open access: yesCiência Rural, 2009
The search for low chill cultivars for peach production in areas with low chill accumulation (temperatures below 7.2°C) has stimulated studies about the higher temperatures effects on low chill cultivars.

Brotação de gemas em macieiras 'Imperial Gala' e 'Fuji Suprema' pelo uso de Erger® e nitrato de cálcio Budbreak in 'Imperial Gala' and 'Fuji Suprema' apples by use of Erger and calcium nitrate

open access: yesRevista Brasileira de Fruticultura, 2010
Apesar da alta eficiência de algumas substâncias químicas na indução da brotação de frutíferas de clima temperado, a elevada toxicidade apresentada por esses compostos é um dos principais problemas relacionados ao seu uso. Resultados preliminares indicam
