The study of phenology can contribute to improve the productivity of crops and fruit quality. The study was conducted to evaluate the reproductive phenology of red pitaya in Lavras, MG, Brazil. It was evaluated in one hundred plants of pitaya (Hylocereus undatus (Haw.) Britton & Rose) the subphases periods from the issuance of buds to fruit ripening from 2008 to 2010. The bud develops from 19 to 21 days. The anthesis is nocturnal which lasts about 15 hours. The maturation occurs from 30 to 40 days after flower opening, when the fruit acquires color pink to deep red and firm texture. In Lavras, MG the reproductive period of red pitaya occurs from November to May and the time of appearance of flower buds to fruit harvest is from 50 to 60 days.

Researches suggest that the chemical thinning with appropriate phytoregulators concentrations must be used for more than one year, in order to improve the quality of ‘Ponkan’ tangerines. Thus, the chemical thinning was applied for two years, in this study, in order to evaluate the physicochemical characteristics of ‘Ponkan’ ( Citrus reticulata Blanco) tangerines. The evaluation process was conducted in a twelve-year-old tangerine orchard, grafted on ‘Rangpur’ lime ( Citrus limonia Osbeck), spaced 6.0 m among rows and 3.0 m among plants. The plants were sprayed with four Ethephon concentrations (200 mg L -1 , 400 mg L -1 , 600 mg L -1 and 800 mg L -1 ), after the period of physiological fruit drop, when fruits reached 25-30 mm in transversal diameter, in January 2009 and January 2010. Plants without spraying were used as control. The experimental design was randomized blocks, with four blocks and four plants per plot. There was interaction between the Ethephon concentrations and years of thinning application for percentage of thinning, number of fruits, mass, transversal and longitudinal diameter, soluble solids contents, titritable acidity, ratio and total sugar. There was no effect of Ethephon concentrations for juice yield. The chemical thinning regularity with Ethephon application increased mass, transversal and longitudinal diameter, soluble solids and ratio of ‘Ponkan’ tangerines.

The red pitaya is a fruit cactus native from the rainforests of Mexico, Central America and South America that has shown great potential in domestic and foreign markets, due to its hardiness and exotic appearance. The work was carried out to evaluate the influence of organic fertilizers and the application of Lithothamnium (calcified seaweed) on production and fruit quality of red pitaia [ Hylocereus undatus (Haw.) Britton & Rose]. The experimental design was a randomized block with eight treatments: control (no fertilization), cattle manure (CaM), chicken manure (ChM), calcified seaweed (CS), cattle manure + chicken manure, cattle manure + calcified seaweed, chicken manure + calcified seaweed and cattle manure + chicken manure + calcified seaweed. The fertilizers were applied every three months since September 2008, with three blocks, and the experimental unit consisted of four plants. The analyzes done were: yield , number of fruits per plant, fruit mass, pulp yield, transverse diameter, longitudinal diameter, peel thickness, soluble solids (SS), titratable acidity (TA), pH and SS/TA ratio. The highest productivities were obtained in treatments containing CaM + ChM + CS (7.16 t ha-1) and CaM + ChM (6.90 t ha-1) in 2011, and the first treatment also showed higher productivity in 2012 (9.40 t ha-1). Greater number of fruits per plant was obtained when fertilization was carried out with CaM + ChM + CS in the two years evaluated. There were no significant differences among the chemical characteristics of red pitaia fruits with different fertilizations.

Recentemente, algumas especies de cactaceas tem-se destacado quanto ao potencial como frutiferas, sendo suas frutas utilizadas como alimento para o homem. dentre essas, a pitaia tem despertado grande interesse. O presente trabalho teve como objetivo estudar a floracao e a frutificacao em diferentes tipos de cladodios (tamanho e presenca ou ausencia de frutificacao em safras anteriores) de pitaia-vermelha em Lavras-MG. As observacoes foram realizadas em plantas de pitaia-vermelha [Hylocereus undatus (haw.) Britton & Rose], com quatro anos de idade, tutoradas em mouroes de eucalipto com 1,80 m de altura, no espacamento de 3 x 3 m. Do surgimento do botao floral ate a abertura da flor, decorreram cerca de 21 dias, e da antese ate a colheita do fruto, cerca de 35 dias. Cladodios que ja haviam produzido frutos em anos anteriores e com tamanho entre 40 e 60 cm de comprimento apresentaram maior porcentagem de cladodios com frutos e maior numero de frutos por cladodio.

Currently, there is lack of information about cutting rooting of olive cultivars for the highlands of MantiqueiraRange, in Minas Gerais. The objective of this study was to evaluate the rooting of different cultivars using perlite andsand as substrates. Cuttings of cultivars Maria da Fe, Mission, Penafiel, Grappolo 575, Galega, Ascolano 315 andGrappolo 54 were collected in January and prepared with approximately 12 cm in length, 4 mm in diameter and 4internodes, keeping four leaves in the first two nodes. The cuttings were treated with 3 mg L
