Physiological processes characteristic of ripening in tissues of intact tomato fruit (Lycopersicon esculentum Mill.) were examined in excised pericarp discs. Pericarp discs were prepared from mature-green tomato fruit and stored in 24-well culture plates, in which individual discs could be monitored for color change, ethylene biosynthesis, and respiration, and selected for cell wall analysis. W...

The genetic and environmental variation for flesh color of tomato (Lycopersicon esculentum Mill.) fruit was quantified using 41 red-fruited breeding lines, open-pollinated cultivars, and hybrids that are representative of the diversity of tomatoes grown for whole-peel processing in the midwestern and eastern United States and Ontario, Canada. Objective color measurements were made for 2 years f...

the use of compounds inhibiting ethylene production is very important in post-harvest technology of fruits. sweet cherry is a non-climacteric fruit with capability of ethylene production during storage period. factors that decrease ethylene production would increase fruits storage life. in this research sweet cherry fruits of mashhad cv. were sprayed with different concentrations of salicylic a...

green olive cultivars “manzanila” and “mission” were harvested at the mature green stage. they were either treated with 1-methylcyclopropane (1-mcp) at a concentration of 1.8 µl/l for 24 h at 20°c or kept untreated as a control. both treated and untreated fruits were then immersed in water containing cacl2 of 0 (control), 50 and 100 mm for 2 h under 1.2 bar pressure. fruits were then surface dr...

Anthocyanin pigments readily degrade during processing and storage of foodstuffs, which can have a dramatic impact on color quality and may also affect nutritional properties. Total anthocyanin pigment content and indices for polymeric color and browning are easily measured with simple spectrophotometric methods. Once individual pigments are identified, their changes can be monitored by high-pe...

production of high quality with high shelf life of apple fruits, is of great importance. present study investigates the effects of ammonium nitrate and iron on quality and antioxidant properties of apple fruit cultivar gala in a randomized complete block design. foliar application of iron chelate in three levels (0, 5 and 10 mg/l) and soil nutrition of ammonium nitrate in three levels as strip ...
