Neste trabalho foi determinado o efeito da concentração da solução nutritiva no crescimento e na produtividade de minitubérculos de batata em um sistema hidropônico fechado empregando areia como substrato. Plântulas micropropagadas e minitubérculos foram plantados em 24 de março de 2004. Os tratamentos foram cinco soluções nutritivas com condutividades elétricas (CE) de 1,0 (T1), 2,2 (T2), 3,4 (T3), 4,7 (T4) e 5,8dS m-1 (T5). O experimento foi conduzido em parcelas subdivididas no delineamento inteiramente casualizado com três repetições. Plantas originadas de minitubérculos produziram mais massa fresca total e média de minitubérculos, massa seca da parte aérea e maior índice de área foliar que plantas micropropagadas. Entretanto, maior massa seca dos minitubérculos foi obtida em plantas micropropagadas. A concentração da solução nutritiva não afetou o número de minitubérculos. O aumento da CE reduziu a massa seca total e dos minitubérculos de plantas micropropagadas e decresceu linearmente o crescimento e a produtividade de minitubérculos de plantas oriundas de minitubérculos. Concentrações baixas de solução nutritiva com valores da ordem de 1,0dS m-1 podem ser empregadas na produção de minitubérculos de batata a partir de plântulas micropropagadas e minitubérculos. |

The adaptive processes by which the vines respond to increase of bud number, in relation to vegetative growth, productivity and grape quality are well known, however the information regarding the increase of bud load in temporal dynamics of the main fungal diseases, especially botrytis bunch rot, are scarce. In this context, the objective of this work is to evaluate the effect the increasing bud load on temporal dynamics of botrytis bunch rot in Cabernet Franc grapevine. This experiment was conducted during the 2016/2017 vintage, in a commercial vineyard, located in the city of São Joaquim, São Catarina State, Southern Brazil, at 1230 meters above sea level. Cabernet Franc plants grafted on the 'Paulsen 1103' rootstock were used. The treatments consisted of four different bud loads: 15, 30, 50 and 75 buds/plant. Pruning was performed on September 08, 2016. It was left 8, 15, 25 spurs with two buds each for treatments 15, 30 and 50 buds per plant, and for the treatment 75 buds per plant, 30 spurs with two buds were left, and two shoots with 8 buds each. The incidence of botrytis bunch rot was obtained through visual evaluation and severity assessed through a diagrammatic scale. With data obtained incidence and severity progress curves were plotted, and the epidemic was compared in relation to: beginning of symptom appearance (BSA) (days); time to reach maximum disease incidence/severity (TRMDI and TRMDS) (days); maximum disease incidence/severity (Imax and Smax) (%); area under the incidence/severity disease progress curve (AUDIPC and AUDSPC). The experimental design was a randomized block design with four blocks and five plants per plot. Disease incidence data were transformed by square root sine arc to normalize the statistical distribution. The data were submitted to analysis of variance (ANOVA) and compared by Tukey test (p <0.05). Effect of bud load on epidemiological variables of botrytis bunch rot was observed. Increasing bud load resulted in an increase in maximum incidence and severity of the botrytis bunch rot of Cabernet Franc clusters. For the variable AUDIPC, it was observed that loads of 50 and 75 buds/plant presented the highest values, with 1585.9 and 1667.9, respectively, while the load of 30 buds/plant presented AUDIPC of 1194.6, and the lowest AUDIPC value was observed in the load of 15 buds/plant, with 760.1. The AUDSPC presented similar behavior, considering that highest values were observed in loads of 50 and 75 buds/plant, presenting values of 54.7 and 63.4, respectively, and the lowest value was observed in load of 15 buds/plant, with a value of 15.0. It is concluded that increasing bud load results in an increase in occurrence of botrytis bunch rot, and it is necessary to adopt a series of preventive measures, such as: early leaf removal, clusters cleaning, and preventive phytosanitary treatments, in order to reduce damages caused by the fungus on Cabernet Franc.
