Cupuassu (Theobroma grandiflorum [Willd. ex Sprengel] Schumann) seeds constitute the raw material for oil extraction and fabrication of cupulate (product similar to chocolate). However, fungal diseases such as witches? broom caused by Moniliophthora perniciosa have interfered with the large-scale development of cupuassu plantations. Cupuassu genetic breeding programmes focus
on a variety of biotechnological tools or approaches to select genes related to quality or resistance mechanisms. In this study, we used expression and interactomics analyses of preselected genes
involved in fruit quality and/or resistance to better understand the molecular and physiological mechanisms associated with these plant processes. It was found that (i) resistant and susceptible
cupuassu genotypes showed different pulp characteristics as well as gene expression patterns; (ii) monosaccharide and carbohydrate transport pathways were enhanced during fruit maturation;
(iii) sugar accumulation participated in signal transduction associated with fruit development and stress response in maturing fruits; and (iv) maturing pulp and seeds showed increased phospholipid
metabolism and translocation, as well as immune system activation. The TgSTP1, TgWRKY33, TgCZF1, and TgUBA1 genes in cupuassu and the orthologues of DIN10, CNI1, and TET8 identified
by the interactomics approach may be good candidates for marker-assisted selection in breeding programmes focusing on both fruit quality and resistance/tolerance to biotic/abiotic stress.

The aim of this study was to evaluate the efficacy of metamitron or metamitron plus benzyladenine as a post-bloom thinner on ‘Baronesa’ and ‘Fuji’ apples. Three experiments (rate, timing and BA combination) were conducted during two crop seasons, 2013/14 and 2014/15 at the experimental station located in Caçador, SC. Fruit set, fruit drop, yield per tree, fruit size and flowering return were assessed. The efficacy of metamitron was affected by time of application, and when applied at petal fall, promoted the proper adjustment of the production load of plants. Yield per plant reduces, whereas the allocation of fruits in categories of greater size increases proportionally to the increase in the metamitron concentration applied. However, there is excessive fruit drop with the use of high concentrations. The addition of BA to metamitron also promoted fruit drop; however, no difference was observed between single application of metamitron and BA addition. Metamitron shows great potential to be used as thinner for apples, since it reduces the number of fruits per tree. Index terms: Malus domestica, post-bloom thinning, fruit drop, return bloom, fruit quality. METAMITRON NO RALEIO QUÍMICO DA MACIEIRA O objetivo deste estudo foi avaliar o efeito de diferentes épocas e concentrações de metamitron e a mistura com benziladenina, no raleio químico em pós-floração das macieiras ‘Baronesa’ e ‘Fuji’. Foram conduzidos três experimentos durante as safras agrícolas de 2013/2014 e 2014/2015, no município de Caçador-SC. Foram avaliados: a frutificação efetiva, a queda de frutos, a produção por planta, a distribuição dos frutos em classes de calibre e o retorno de floração. A época de aplicação de metamitron influenciou a eficiência do produto, sendo que, quando aplicado na queda de pétalas, este promoveu o adequado ajuste da carga produtiva das plantas. A produção por planta reduz, enquanto a alocação dos frutos em categorias de maior calibre aumenta, proporcionalmente ao aumento da concentração de metamitron aplicada. No entanto, há queda excessiva de frutos com a utilização de concentrações elevadas. A mistura de metamitron com benziladenina, promove a queda de frutos, porém não há efeito aditivo entre a mistura e a aplicação individual de metamitron. O princípio ativo metamitron tem potencial para uso num programa de raleio químico em macieira, visto que reduz a frutificação.
