“…The position of the fertile bud influences the pruning system to be adopted, for varieties that have low fertility of basal buds, it is necessary to adopt a long or mixed pruning system. By adapting the type of pruning to the position of the most fertile buds it is possible to increase productivity, as there will be an increase in the number of inflorescences and consequently an increase clusters produced per vine (Srinivasan & Mullins, 1981;Brighenti et al 2017;Würz et al 2019).…”

“…In many cases less than one cluster per bud is observed, resulting, in most grapevine varieties, annual variations in productivity (Rosa et al 2014;Würz et al 2019). Several causes may be related to low bud fertility, for example, genetic diversity, pruning method, temperature, light intensity, mineral nutrition and hormone concentrations (Srinivasan & Mullins, 1981;Dokoozlian, 2000;Botelho et al 2009;Andreini et al 2009;Taiz & Zeiger, 2009;Brighenti et al 2017).…”

Low bud fertility index is frequently observed in different grapevine varieties grown in high altitude of Santa Catarina Sate; in many cases less than one cluster per bud is observed. The objective of this study was to assess bud fertility of twenty six Vitis vinifera L. varieties and from this information, to recommend the method of pruning more suitable for these varieties in high altitude conditions. The grapevine canes and buds were collected from production vineyards located in São Joaquim, Santa Catarina State, in two consecutive vintages. Fifteen cane cuttings containing 10 nodes per variety were collected to determine bud fertility and placed in a growth chamber with controlled relative humidity, light, temperature. After budbreak, buds were classified as fertile or non-fertile according to the presence or absence of the inflorescence. The bud fertility varies according to the variety and its position in the cane. Merlot, Cabernet Franc, Cabernet Sauvignon, Tinta Roriz and Tinta Caiada, which present higher fertility in basal buds, are recommended for short or long pruning. The varieties Chardonnay,

“…Essa redução da fertilidade de gemas, está associado ao maior adensamento do dossel vegetativo, reduzindo a interceptação da radiação fotossinteticamente ativa, e consequentemente reduzindo a fertilidade de gemas. Para BRIGHENTI et al (2017), adaptando o tipo de poda com a posição das gemas mais férteis é possível aumentar a produtividade, pois haverá um aumento no número de gemas férteis ao adotar o sistema de poda adequado para cada variedade, e em cada manejo da videira.…”

Efeito da carga de gemas da videira 'Cabernet Franc' na interceptação da radiação solar e na fertilidade de gemasEffect of retained node numbers of Cabernet Franc grapevine on the interception of solar radiation and on the node fertility RESUMO Devido a uma carência de informações técnico-cientificas sobre o efeito da carga de gemas em relação a interceptação da radiação solar, e o seu efeito na fertilidade de gemas, tem-se como objetivo desse trabalho avaliar o efeito do aumento da carga de gemas da videira 'Cabernet Franc' em relação a interceptação da radiação fotossinteticamente ativa e o seu efeito na fertilidade de gemas em região de elevada altitude de Santa Catarina. Este experimento foi conduzido durante safra 2016/2017, em um vinhedo comercial, localizado no munícipio de São Joaquim. Utilizaram-se plantas de 'Cabernet Franc' enxertadas sobre o porta-enxerto 'Paulsen 1103'. Os tratamentos consistiram em quatro diferentes níveis de cargas de gemas: 15, 30, 50 e 75 gemas planta -1 . O delineamento experimental utilizado foi o de blocos ao acaso, com quatro blocos e cinco plantas por parcela. Os dados foram submetidos à análise de variância (ANOVA) e comparados pelo Teste Tukey a 5% de probabilidade de erro. Os resultados desse estudo evidenciam a importância da interceptação da radiação fotossinteticamente ativa na fertilidade de gemas, observando-se redução da fertilidade de gemas em situações de redução da interceptação da radiação fotossinteticamente ativa, nesse caso, causado pelo aumento da carga de gemas, que resulta em um maior número de ramos, proporcionando um dossel mais denso, reduzindo a interceptação da radiação fotossinteticamente ativa que alcança as gemas da videira, sendo esse efeito, mais pronunciado nas gemas localizada na posição basal do ramo. PALAVRAS-CHAVE:Vitis vinifera L., poda, equilíbrio vegetativo, manejo do dossel. ABSTRACTDue to a lack of technical-scientific information about the effect of the retained node number on the interception of the solar radiation of the nodes and its effect on the fertility of nodes, this work aims to evaluate the effect of the increased number of nodes of the grapevine Cabernet Franc in relation to the interception of the photosynthetically active composition and its effect on the node fertility in high altitude region of Santa Catarina State. This experiment was conducted during the 2016/2017 harvest in a commercial vineyard located in the city of São Joaquim. Cabernet Franc plants grafted on the 'Paulsen 1103' rootstock were used. The treatments consisted of four different levels of retained node numbers: 15, 30, 50, and 75 nodes per plant. The experimental design was a randomized block design with four blocks and five plants per plot. The data were submitted to analysis of variance (ANOVA) and compared by the Tukey test with a 5% probability of error. The results of this study evidenced the importance of the interception of the photosynthetically active radiation in the nodes fertility, observing the reduction of the nodes fertility in situation...

“…However, pruning has the maximum influence on the final yield and quality of a cultivar among the different cultural operations in grapes. And berry quality highly depends on the precision of the pruning (Brighenti et al 2017).…”

“…In this study, three different intensities of pruning were tested on the 'Regent' vines trained with Single Guyot training system, which is a cane-pruned method with spur. The cane buds grow into shoots that produce the yield, in turn the spur buds grow into shoots that can be used as canes in the following vegetative season (Brighenti et al 2017). Vine cultivated in traditional French vineyards is typically pruned to one cane with six to eight buds and one spur with two buds.…”
