1. 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

2. 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

3. Otimização da extração de antocianinas presentes no feijão-preto e impregnação do extrato em matriz polimérica natural para uso como indicador de pH
OPTIMIZATION OF THE EXTRACTION OF ANTHOCYANINS PRESENT IN BLACK BEANS AND IMPREGNATION OF THE EXTRACT IN NATURAL POLYMERIC MATRIX FOR USE AS A pH INDICATOR. In this work, a method of extracting natural indicators, anthocyanins, present in black beans was optimized. The best extraction condition was obtained with 50 g of beans and 93 g of water, under agitati

4. Exogenous gibberellin and cytokinin in a novel system for in vitro germination and development of African iris (Dietes bicolor)
ABSTRACT The availability of reliable and reproducible micropropagation systems is a decisive step to successfully propagate plant species with slow growth and low germination rate. The effect was investigated of gibberellin (GA) and cytokinin (CK) in the in vitro germination and development of Dietes bicolor (Steud.) Sweet ex Klatt. Seeds were inoculated in

5. Yield and morphological attributes of bell pepper fruits under biological fertilizers and application times
ABSTRACT Bell pepper (Capsicum annuum) is one of the most consumed vegetables around the world. Balanced fertilization is essential for growing this vegetable. The objective of this study was to evaluate the yield and morphological attributes of bell pepper under doses and times of application of biological fertilizers. Two experiments were carried out with

6. Budbreak induction in kiwifruit vines cultivated in an organic system by the biological method of single node cutting
ABSTRACT Kiwifruit vines are an alternative approach to diversify Brazilian fruit farming because of the low supply and increase in the demand for their fruits. Hydrogenated cyanamide, which is the most common rest-breaking agent, is highly toxic and its use is not allowed in organic production systems. This study aimed at evaluating the efficiency of altern

7. VITRO OF Melanoxylon brauna SCHOTT. MORPHOGENESIS: RESPONSIVENESS OF EXPLANTS TO PERMANENT AND TEMPORARY IMMERSION GROWTH REGULATORS
ABSTRACT Melanoxylon brauna is propagated by seeds, however, low yield, pest attack and short viability are problems in seedling production. In vitro cultivation is an alternative for large-scale seedling production, but studies with this species are scarce. The aim of the work was to analyze the in vitro morphogenesis of braúna. Explants after induction of

8. Fertility of buds and pruning recommendation of different grapevine varieties grown in altitude regions of Santa Catarina State, Brazil
ABSTRACT 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 s

9. Alternative budburst management in Campanha Gaúcha vineyards
Resumo Buscando uma alternativa menos tóxica que a cianamida hidrogenada para o manejo da brotação, doses do produto organomineral Erger® foram testadas em combinação com nitrato de cálcio (Ca(NO3)2). O experimento foi conduzido em Santana do Livramento, região Sul do Brasil, durante os ciclos de 2013/2014 e 2014/2015, em um vinhedo ‘Merlot’, co
