El tomate es la hortaliza de fruto más cultivadas a nivel mundial. De esta existen múltiples genotipos, que están genéticamente creados para condiciones ambientales muy específicas, por ello es importante conocer el comportamiento postcosecha de los frutos, que resultará en el cultivar mejor recomendado para cada región. El objetivo general fue: realizar la caracterización fisicoquímica y postcosecha de tres genotipos de jitomate, cultivados bajo condiciones de invernadero, en Tehuacán Puebla, México. La investigación se llevó a cabo en laboratorio. Los genotipos fueron: Merlisse, Maxcesa y Komet tipo bola, cultivados bajo invernadero. Las variables respuesta fueron: diámetro ecuatorial y polar, dinámica del peso de fruto, color de fruto, firmeza, contenido de Ca++ y K+ y vida postcosecha. El diseño utilizado fue completamente aleatorizado, cuyos tratamientos fueron los cultivares y siete repeticiones (3 x 7)= 21 unidades experimentales. Los resultados indican, que el mayor diámetro ecuatorial y polar así como pérdida de peso, fueron en Maxcesa, mientras que Komett, presentó la mayor firmeza y contenido de Ca++ y K+, siendo este último quien presentó la mayor vida de anaquel. De esta investigación se puede concluir, que el cultivar Komett, es quien mejor se adapta a las condiciones del valle de Tehuacán, Puebla.

O objetivo desse trabalho foi avaliar a produção, a qualidade e tempo de prateleira de cultivares de tomate tipo italiano de crescimento determinado, produzidos sob ambiente protegido em condições de altas temperaturas. O cultivo foi realizado em Nova Mutum – MT, foram avaliados cinco cultivares: Fascínio (Feltrin sementes), Hy Color (Horticeres), Santa Adélia (TopSeed), SM-16 (Seminis) e Supera F1 (TopSeed), dispostos em blocos casualizados, com quatro repetições. As plantas foram conduzidas em “meia estaca” e não foram podadas. Os parâmetros avaliados foram relativos a produção, a qualidade dos frutos, tempo de prateleira e qualidade no pós-colheita. A cultivar Fascínio apresentou produtividade de 186,1 t ha-1, maior massa média de frutos (144,3g), maior calibre de fruto, (60,7mm), e menor perda de massa no pós-colheita (6,23%). Os melhores resultados de sólidos solúveis totais dos frutos que completaram a maturação na planta foram obtidos das cultivares Santa Adélia (4,3), Fascínio (4,27) e Hy Color (4,21), e dos frutos colhidos no estádio verde-maduro obteve destaque a cultivar Santa Adélia (5,85), e os frutos que ficaram em temperatura ambiente obtiveram maior média de sólidos solúveis totais (5,55). Palavras-chave: termotolerância; Lycopersicum esculentum Mill; produtividade; pós colheita; ambiente protegido.   The performance of determinate growth italian tomato cultivars in protected cropping under high temperatures   ABSTRACT: This study aimed to evaluate the production, quality and shelf time of determinate growth Italian tomato cultivars from a protected environment under high temperature conditions.  The cultivation was conducted in Nova Mutum, state of Mato Grosso, Brazil. Five cultivars were evaluated: ‘Fascínio’ (Feltrin Sementes), ‘Hy Color’ (Horticeres), ‘Santa Adélia’ (TopSeed), ‘SM-16’ (Seminis) and ‘Supera F1’ (TopSeed), disposed in randomized blocks with four repetitions. The plants were managed into the “meia estaca” tutoring method and were not pruned. The parameters evaluated were related to the production, quality of fruits, shelf time and postharvest quality. The ‘Fascínio’ cultivar presented productivity of 186.1 t ha-1, the largest average fruit weight (144.3 g), the largest fruit gauge (60.7 mm) and the smallest postharvest weight loss (6.23%). The total soluble solids best results of fruits that have matured in the plant were obtained from the ‘Santa Adélia’ (4.3), ‘Fascínio’ (4.27) e ‘Hy Color’ (4.21) cultivars. Among the fruits harvested at the mature-green stage, the ‘Santa Adélia’ (5.85) cultivar stood out. The fruits that stayed at room temperature obtained the largest total soluble solids average (5.55). Keywords: thermotolerance; Lycopersicum esculentum Mill; productivity; postharvest; protected environment.

Salah satu jenis tanaman hortikultura penting yang banyak dikembangkan di Indonesia adalah tanamantomat (Lycopersicum esculentum Mill). Beberapa cara dapat dilakukan untuk meningkatkan produksi dan kualitastanaman yang salah satunya adalah dengan mendapatkan varietas unggul baru. Pada tahapan ini maka perludiseleksi terlebih dahulu jenis tomat yang mempunyai hasil baik dan toleran terhadap gangguan organismepenggangu tanaman (OPT). Tujuan penelitian ini adalah untuk mendapatkan kultivar tomat yang baik dari segipertumbuhan yang dapat dijadikan sebagai sumber genetik untuk bahan persilangan. Dalam percobaan inidilakukan identifikasi dan karakterisasi 11 kultivar tomat hasil introduksi yang terdiri dari A: ‘Oxheart’; B:‘Moskvich’; C: ‘Valencia’; D: ‘Marmande’; E: ‘Moneymaker’; F: ‘La Sweetie’; G: ‘Principle Borghese’; H:‘Golden Sunrise’; I: ‘Red Cherry’; J: ‘Black Cherry’; dan K: ‘Golden Jubille’. Hasil pengamatanam menunjukkanbahwa setiap kultivar tomat introduksi mempunyai respon pertumbuhan yang berbeda. Tomat ‘Black Cherry’menunjukan respon pertumbuhan yang terbaik dengan pertimbangan tinggi tanaman, tinggi tandan pertama,diameter batang tanaman, jumlah bunga per tandan, dan jumlah buah per tandan.Serta mempunyai ketahananterhadap serangan organisme pengganggu.Kata kunci: introduksi, pertumbuhan, tomatABSTRACTOne of the important horticultural crops in Indonensia is Tomato (Lycopersicum esculentum Mill.). Severalmethods can be used to improve productivity and quality of tomato such as by generating new tomato cultivar withdesired characters. To generate new cultivars therefore new selection in parental tomato is needed to get thepotential parental tomato as genetic background. The purpose of this study was to find out the potential tomatocultivars such as high productivity and quality, adaptive grown in Indonesia and also resistant to pest and disease.Eleven tomato cultivars introduction was used in this experiment consisted of A: 'Oxheart'; B: 'Moskvich'; C:'Valencia'; D: 'Marmande'; E: 'Moneymaker'; F: 'La Sweetie'; G: 'Principle Borghese'; H: 'Golden Sunrise'; I:'Red Cherry'; J: 'Black Cherry'; and K: 'Golden Jubille'. The results showed that each introduced tomato cultivarhas a different response to environmental condition. Tomato ‘Black Cherry’ showed the best plant growthcompared to other cultivars. It had the highest plant height; shoot diameter, no of flower per truss, and no of fruitper truss. It also showed as a resistant cultivar to the pest and disease.Keywords: introduction, plant growth, tomato

This work investigates the growth and physiological responses of locally grown tomato cultivars with a known hybrid (Roma-VF cultivars). Seeds of two tomato cultivars: Roma VF (Lycopersicum esculentum Mill.Cv) was collected from National Horticulture Research Institute (NIHORT), Ibadan while the Local tomato: Ife-1 (Lycopersicum esculentum Mill. Cv) obtained from the market woman in the central market, Obafemi Awolowo University, Ile- Ife. The seed of the plant were planted in perforated plastic containers containing soil collected at the base of hill 1(latitude 7’3’9.40 and longitude 4’3’24.52) in Obafemi Awolowo University Ile-Ife, Osun State. The containers placed where they can have access to direct sunlight. The growth parameters of the plants were determined which include the leaf length, width and the shoot size was observed. The weight and growth rate of the shoot were determined. The fruits obtained from all the cultivar were exposed to proximate analysis. It was observed that the shoot of the two cultivars increased in the course of the experiment but at the end the shoot of Roma () was longer than that of local cultivar. More number of leaves was present in Roma compare to local one. Roma has higher moisture content (5.9% M.C)) than the local cultivar (4.7% M.C). Average number of fruits in Roma was (15) which is higher than that of local one (10). From all the parameters observed in this work it was observed that Roma cultivar which is a hybrid do far better in all indication than the local tomato cultivar. This may be as a result of Roma hybrid characteristics such as resistances to disease and unfavorable environmental factors. Equally the improved nutritional value of the Roma tomato and lot of genetically modified features are key to this cultivar (Roma) advancement.

Solid dispersions are one of the most promising strategies to improve the oral bioavailability of poorly water soluble drugs. By reducing drug particle size to the absolute minimum, and hence improving drug wettability, bioavailability may be significantly improved. This article reviews the various preparation techniques for solid dispersion and compiles some of the recent technology transfers. The different types of solid dispersions based on the molecular arrangement have been highlighted. Some of the practical aspects to be considered for the preparation of solid dispersions, such as selection of carrier, solvent and methods of physicochemical characterization, along with an insight into the molecular arrangement of drugs in solid dispersions are also discussed. In this review, it is intended to discuss the recent advances related on the area of solid dispersions.
