Comportamento de gemas dormentes de videira ‘bordô’ em Pinhais, Paraná

Abstract: RESUMO O mecanismo fisiológico da dormência de gemas de espécies frutíferas temperadas ainda não foi totalmente esclarecido, sendo esse conhecimento importante para se entender melhor o comportamento das plantas em diferentes climas. Este experimento teve por objetivo caracterizar a dinâmica de brotação de gemas de videira cv. Bordô, por meio do teste biológico de nós isolados e do teste do tetrazólio. O experimento foi realizado com a coleta quinzenal de ramos de videira, nos meses de maio e agosto, nos anos … Show more

“…MTB of cultivars showed little variation in all collection periods; therefore, cultivars obtained similar responses (Table 2). According to Fowler et al (2018) [24], the highest MTB is characterized as the deepest endodormancy period of cultivars. Thus, cultivars under study showed similar characteristics, that is, the MTB varied between the evaluation periods.…”

“…There was an oscillation in MTB both in dates of collection and in the cultivars under study. Fowler et al (2018) [24] stated that differences in MTB occur due to chill requirements of every cultivar and fluctuations are observed as a function of temperature variations over the period. Furthermore, Petri et al (2021) [1] stated that it is very difficult to determine chill requirements of a species or cultivar under field conditions, since environmental conditions can incite plants to generate different responses.…”
