Cassava wild species are important sources of genes for resistance to biotic constraints that can be used for genetic improvement of the cultivated species, M. esculenta. Cassava green mites (CGM), Mononychellus tanajoa (Bondar), is one of the most important pest affecting cassava crop, mainly in semi-arid environment. Fourteen accessions of six Manihot wild species were evaluated for biological aspects of CGM: 1) M. anomala (4); 2) M. peruviana (4); 3) M. flabellifolia (2); 4) M. dichotoma (2); 5) Manioba, problaby M. glaziovii (1); and 6) Mandioca Sete Anos, problaby a natural hybrid between M. esculenta and a wild species (1). The study was carried out in laboratory under 25±1°C, 70±10% (RH) and 12h of photoperiod. Daily evaluations on development and reproduction of M. tanajoa were performed. The experimental design was completely randomized with 50 replications per genotype. The period from egg to adult varied from 10.08 to 13.99 days, with distinction of five groups. The two groups with the highest periods of egg-adult were composed by the four accessions of M. anomala. The rate of oviposition varied from 0.80 to 2.18 eggs/female/day with distinction of four groups. One accession of M. anomala presented the shortest rate of oviposition. The wild genotypes presented lesser fecundity of M. tanajoa in relation to the cultivated species (M. esculenta), selected as resistant to semi-arid condition in the Northeast Brazil. These results suggest the presence of high levels of source of resistance within wild species of Manihot.

‘Gala’ apple trees have low fruit set in restrictive pollination situations, being an obstacle to the achievement of high production rates in orchards in southern Brazil, which can be minimized by the use of growth regulators. The aim of this study was to evaluate the effect of thidiazuron concentrations in ‘Royal Gala’ apple fruiting and production, grown in mild winter conditions. The experiment was conducted during the 2011/2012, 2012/2013 and 2013/2014 crop years in Fraiburgo, SC, on ‘Royal Gala’ apple trees in Marubakaido rootstock M9 with filter. In all evaluation cycles, the experimental design was a randomized block with factorial arrangement (6x2) with six TDZ concentrations and two application forms, with six replicates, and the experimental unit consisting of one plant. The TDZ concentrations of each treatment were applied split into two seasons. The first application was performed on pink bud stage (E2) and the second application was in full bloom stage (F2). The variables evaluated were: fruit set (%), return bloom (%), number and weight of fruits per plant, mean fruit weight (g) and average number of seeds per fruit. Data were submitted to analysis of variance, in which for significant variables by the F test, analysis of contrast and polynomial regression were performed in order to evaluate the response of variables with increasing TDZ concentration. TDZ is effective even at low concentrations, increasing the production and fruit set of ‘Gala’ apples in the climatic conditions of southern Brazil. Index terms: Malus domestica Borkh., growth regulators, cytokinin, fruit set.

Em todos os ciclos de avaliação, o delineamento experimental foi em blocos casualizados, com esquema fatorial (6x2), com seis concentrações de TDZ e duas formas de aplicação, com seis repetições, sendo a unidade experimental composta por uma planta. As concentrações de TDZ respectivas a cada tratamento foram aplicadas parceladamente em duas épocas. A primeira aplicação foi realizada no estádio de balão rosado (E2 ), e a segunda aplicação, no estádio de plena floração (F2 ). Foram avaliadas as variáveis frutificação efetiva (%), retorno de floração (%), número e massa fresca (kg) de frutos por planta, massa fresca média de frutos (g) e número médio de sementes por fruto. Os dados obtidos foram submetidos à análise de variância, em que, para as variáveis significativas pelo teste F, foi realizada a análise de contrastes e de regressão polinomial com a finalidade de avaliar a resposta das variáveis com o aumento da concentração.
