“…O principal centro de diversidade da abóbora é o continente americano, mais precisamente a área central do México. As abóboras consistem em plantas de clima quente, com temperaturas ótimas para o desenvolvimento e frutificação, variando de 20 a 27 ºC (Ferreira et al, 2017). Conforme Amaro et al (2014), a abóbora conhecida como 'Tetsukabuto' ou 'Cabotiá' é um híbrido interespecífico, resultado do cruzamento entre linhagens selecionadas de moranga (Cucurbita maxima Duch.…”

ResumoO aumento pela busca por alimentos saudáveis, sem glúten e ricos em fibras abre oportunidade para a incorporação de olerícolas, como a abóbora. A secagem e o armazenamento são etapas essenciais para a obtenção de produtos de qualidade, contribuindo para minimização de perdas e, consequentemente, aumentando a vida útil dos produtos. Objetivou-se, com esta pesquisa, avaliar a cinética de secagem das raspas de abóbora em diferentes condições de secagem, bem como determinar suas propriedades termodinâmicas. Realizou-se a secagem das raspas de abóbora em sombra, estufa e secador experimental. Diversos modelos de regressão não linear foram ajustados aos dados experimentais para caracterizar o processo de secagem. A partir do modelo de Arrhenius foram obtidos os coeficientes da difusão e a energia de ativação para o cálculo da entalpia, entropia e energia livre de Gibbs. Conclui-se que Page foi o melhor modelo para representação da cinética de secagem das raspas de abóbora. A elevação da temperatura do ar de secagem proporciona o aumento da energia livre de Gibbs e da difusividade de água nas raspas de abóbora, reduz a entalpia e mantém a entropia negativa.

“…The average yield obtained with the 300 kg ha −1 dose of P2O5 in the second growing season is higher than the average yield observed for the state of Minas Gerais of 15 ton ha −1 (Sediyama et al, 2009), however. Lower than the average productivity observed by Ferreira et al (2017), for the state of Tocantins.…”

Growing Japanese hybrid squash has been a cost-effective alternative to growers; however, several factors directly influence plant growth and development, nutrition being one of the main ones. Data regarding the nutrition of these vegetables are scarce. The objective of this study was to verify the effect of phosphorus doses applied via soil, on fruit yield of Japanese hybrid squash. Two experiments were conducted in 2017, May 1 through July and September 2 through November, in the experimental area of the Olericulture Sector of the Federal University of Tocantins. For the development of both experiments, it was used the Divina ® cultivar owned by the company "Horticeres seeds". The experimental design was randomized blocks with five treatments and four replications, as follows: 0; 75; 150; 225 and 300 kg ha −1 of P2O5. The characteristics evaluated were: productivity (ton ha −1 ), average fruit mass (kg), number of flowers per parcel (unit), transverse diameter (cm) and phosphorus content in Japanese squash (g kg −1 ). The mean values related to the study variables were submitted to analysis of variance, and subsequently, regression analysis. The 300 kg ha −1 dose of P2O5 provided higher yield and average fruit mass. In both growing seasons. Cultivation of the Japanese hybrid squash between September and November showed higher productivity.

“…The use of the synthetic cytokinin forchlorfenuron (CPPU) resulted in good quality production for several fruit species, this effect being confirmed by Ding et al (2013) in tomatoes, Li et al (2017) in cucumber and Zhang et al (2017) in kiwi. As well as the use of synthetic auxins, aiming at asexual production for the formation of parthenocarpic fruits, as stated by Ferreira et al (2017) with the use of dichlorophenoxyacetic acid (2,4-D) in Japanese pumpkin. Pereira et al (2014), working with 'Gefner' atemoya, observed that the exogenous application of 1-naphthalene acetic acid (NAA), associated with gibberellic acid promoted high fruiting in a similar way to artificial pollination.…”

The use growth regulators from the cytokinins and auxins group has been shown to increase the productivity of certain crops, as they may be involved in the expression of plant sex, although little is known about the action of auxin IBA and cytokinin CPPU on the fruiting of squash, as well as the interaction between both, which makes this field of study promising. Thus, the objective of this study was to induce the fruiting in Atlas squash, by means of different forms of application and proportions of cytokinin and auxin and to evaluate their effects on the physical-chemical characteristics of the fruits. The treatments were composed of six proportions associated with growth regulators and of two forms of application. The experimental design was a randomized block design with four replicates. At 72 days after transplanting, growth and fruit quality analyses were performed. The behavior of the hormones is modulated by their concentration and place of application, and the effect may be beneficial or not. The proportions 50/50% via leaf and 75/25% via ovary were the ones that increased the growth and parameters of fruit quality. The application of CPPU via leaf at higher concentration in proportion decreases quality characteristics such as vitamin C, carotenoids and starch.
