Ripening progress in each class in relation to RS berries during the first 3-week period To assess the progress of ripening during early-véraison in GH, GS, and PS berries relative to that of RS berries, principle component analyses were performed using TSS, color index, and elasticity data of individual berries from each under-ripe berry class along with those of RS berry class during the firs...

During banana (Musa acuminata L.) fruit ripening ethylene production triggers a developmental cascade that is accompanied by a massive conversion of starch to sugars, an associated burst of respiratory activity, and an increase in protein synthesis. Differential screening of cDNA libraries representing banana pulp at ripening stages 1 and 3 has led to the isolation of 11 nonredundant groups of ...

cantaloupe (cucumis melo var. cantalopensis) is an important vegetable crop and is grown on 35000 hectares in iran, mostly in tehran, markazi, qom, esfahan, khorasan, semnan, booshehr and hormozgan provinces. to improve local semsoori population for concentrated yielding, a breeding program was initiated in 2000 in varamin agricultural research center, varamin, iran. in the first step a mass se...

F.A. Tomás-Barberán 7 F. Artés Departamento de Ciencia y Tecnología de Alimentos, CEBAS (CSIC), P.O. Box 4195, E-30080 Murcia, Spain Abstract For five new clones of pomegranate, cultivated under homogeneous conditions, changes in juice anthocyanin contents during ripening were studied. Six anthocyanin pigments were found to be responsible for the red color of pomegranate juice. These were quant...

The activity of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) and the level of its mRNA have been determined at various stages of tomato fruit development. The HMGR reaction makes mevalonate, a necessary component in the synthesis of all isoprene containing compounds, such as sterols and carotenoids. A cDNA clone encoding the active site region of HMGR has been isolated from a tomato l...

The application of edible coatings carrying antifungal compounds on cheese was studied to reduce mass losses and control the fungal growth surface during ripening. effectiveness 8 biopolymers Aloe vera gel (AV) at controlling loss analysed early stage maturation, with without lipids (Oleic acid oleic acid-beeswax blend) (potassium sorbate (PS)), gallic tannin (GT) gel. gellan gum both PS GT exh...

The fundamental cause of alternate bearing in pecan [Carya illinoinensis (Wangenh.) K. Koch] is unknown, but is closely linked to the size of the dormant season carbohydrate pool. Nut yields (over a period of up to 78 years) were evaluated, for 66 cultivars, in regards to alternate bearing intensity (I). Best-fit regression analysis indicates no association between I and fruit ripening date (FR...

Cherimoya (Annona cherimola Mill.) is a subtropical fruit characterized by a significant increase in organic acid levels during ripening, making it an interesting model for studying the relationship between acidity and fruit flavor. In this work, we focused on understanding the balance between the concentration of organic acids and the gene expression and activity of enzymes involved in the syn...

The physiological effects of reduced ethylene synthesis in a transgenic tomato (Lycopersicon esculentum) line expressing 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase enzyme have been examined. Fruit from the transgenic line 5673 ripen significantly slower than control fruit when removed from the vine early in ripening. In contrast, fruit that remain attached to the plants ripen much mo...
