1. Chilling requirement of four peach cultivars estimated by changes in flower bud weights
ABSTRACT The adaptation of temperate fruit crops is a challenge being increased by the global warming. Chilling requirement is a key factor for adaptation. The objective of this study was to estimate the chilling requirement of peach cultivars BRS Bonão, Esmeralda, Granada and Eragil, using the Tabuenca test. Chilling accumulation was computed using four di

2. Chilling and forcing requirement of five international fig cultivars grown in Southeastern Brazil
ABSTRACT Chill hours availability influence break dormancy, sprouting and production of temperate fruits trees in different regions. However, there are few reports on the subject for fig tree. This study aimed to evaluate the effects of the accumulated chilling hours on the physiology and dormancy release of fig cultivars. Stem cuttings of five fig cultivars

3. Rootstock-scion interaction:6. Phenology, chilling and heat requirements of Cabernet Sauvignon grapevine
Resumo A fenologia da videira depende de vários fatores, como genética, características do solo, condições climáticas, pragas e doenças, e práticas culturais do vinhedo. Dentre estas, o porta-enxerto pode ter influência no comportamento da copa. Devido a isso, este experimento foi conduzido por dois anos para determinar o efeito do porta-enxerto na

4. ‘SCS425 Luiza’: new apple cultivar with medium chilling requirement and resistant to glomerella leaf spot (colletotrichum spp.)
Resumo A maçã é um dos principais produtos do agronegócio da fruticultura temperada do Sul do Brasil. Mais de 90% da produção são originadas com o cultivo de apenas duas cultivares – Gala e Fuji, e seus mutantes. Essas cultivares são pouco adaptadas ao clima regional, sendo as do grupo ‘Gala’ também suscetíveis à doença mancha foliar de gl

5. Advances in the production of temperate fruits in the tropics
ABSTRACT. The present study aimed to review the advances in the production of temperate fruits to determine future research directions that improve production in the tropics. Temperate fruits are no longer only produced in regions characterized by a cold winter period. These fruits are also produced in the sub-tropical and tropical regions characterized by m

6. Seleção de pessegueiro com base na necessidade de frio da semente e qualidade do fruto / Peach selection based on the seed chilling requirement and fruit quality
The peach [Prunus persica (L.) Batsch] is a temperate species that can be grown in areas with mild winter climates by the use of adapted genotypes. This species have dormant buds and seeds, and the exposure to low temperatures is the main way to overcome dormancy in these two organs. Generally, plants that have low chilling requirement to overcome dormancy o

7. Indução floral de Beta vulgaris L. em condições do Distrito Federal
The demand for beet seeds in Brazil is growing every year, however, the dependence on imported seeds of this vegetable is almost total. Low temperatures associated with long photoperiods promote flowering and seed production, but this conditions are rare in most of Brazil. The artificial vernalization of roots is a good technique for seed production of vario

8. Combining ability and peach tree selection for low chilling requirement / Capacidade combinatória e seleção de pessegueiro para baixa necessidade de frio hibernal
O pessegueiro (Prunus persica) é uma espécie de clima temperado que pode ser cultivada em áreas com climas apresentando inverno ameno através da utilização de genótipos adaptados. Esta espécie apresenta dormência em gemas e sementes, sendo que a exposição a um período sob baixas temperaturas é a principal forma para a superação da dormência n

9. Seleção de pessegueiro adaptado ao clima subtropical / Peach tree selection adapted the subtropics conditions
The peach is one of fruit species subjected to more research all over the world having a large number of varieties. One of the most important objectives in peach breeding is the low chilling requirement, once it has direct relation with adaptation of the species in areas in mild winters area, characteristic of subtropical regions. Characteristics such as fru

10. Impairment of Photosynthesis by Chilling-Temperatures in Tomato 1
Chilling of attached tomato leaves (cv. Rutgers) in the dark for 16 hours at 1 C decreased both photosynthesis and transpiration. To separate the effects of chilling on stomatal CO2 conductance from more direct effects of chilling on the chloroplasts' activities, measurements of photosynthesis and transpiration were made at atmospheric and saturating CO2 lev

11. Electron transport regulates exchange of two forms of photosystem II D1 protein in the cyanobacterium Synechococcus.
Synechococcus sp. PCC 7942 modulates photosynthetic function by transiently replacing the constitutive D1 photosystem II protein, D1:1, with an alternate form, D1:2, to help counteract photoinhibition under excess light. We show that a temperature drop from 37 to 25 degrees C also drives D1:1/D1:2 exchange under constant, moderate light. Chilling or light-in

12. Gibberellin Requirement for Arabidopsis Seed Germination Is Determined Both by Testa Characteristics and Embryonic Abscisic Acid1
The mechanisms imposing a gibberellin (GA) requirement to promote the germination of dormant and non-dormant Arabidopsis seeds were analyzed using the GA-deficient mutant ga1, several seed coat pigmentation and structure mutants, and the abscisic acid (ABA)-deficient mutant aba1. Testa mutants, which exhibit reduced seed dormancy, were not resistant to GA bi
