Two Chinese jujube (Zizyphus jujuba) cultivars ('Huanghua' and 'Zhanhua') at unripe and ripe stages were investigated. During ripening, the weight, pH, hardness, and chewiness of both cultivars decreased while titratable acidity, total soluble solid content, and pectin contents increased. More than 75% pectins of the fruits were water-soluble pectin (WSP). Pectins shared the common major compos...

The role of auxin in ripening strawberry (Fragaria ×ananassa) fruits has been restricted to the early stages of development where the growth of the receptacle is dependent on the delivery of auxin from the achenes. At later stages, during enlargement of the receptacle, other hormones have been demonstrated to participate to different degrees, from the general involvement of gibberellins and abs...

in this research, the accelerated ripening of the kabkab dates from khalal to tamr using nacl and acetic acid solutions was studied. fruits at khalal stage were harvested and washed with distilled water before being treated with ripening inducers: 1. nacl solutions, 2. acetic acid solutions and 3. aqueous solution of nacl (1%) and acetic acid. moisture, ph, colour, brix and textural firmness of...

in order to study seed hardening process in pomegranate, some of the relevant biochemical parameters were evaluated in fleshy part of arils or seeds in various soft and hard seeded pomegranate genotypes from the initial fruit set upto ripening stages. lignin was determined from the seeds and enzyme assays were performed on the flesh of arils. analysis of variance revealed significant difference...

The present investigations were undertaken to ascertain the extent of lipid peroxidation, oxidative stress and antioxidative system during ripening of two varieties of ber fruits (Ziziphus mauritiana Lam.) differing in their shelf lives, viz. Umran (8–9 days) and Kaithali (4–5 days). Based on visual observations, fruits were categorized as immature green (IG), mature green (MG), turning colour ...

Few molecular studies have been devoted to the finger drop process that occurs during banana fruit ripening. Recent studies revealed the involvement of changes in the properties of cell wall polysaccharides in the pedicel rupture area. In this study, the expression of cell-wall modifying genes was monitored in peel tissue during post-harvest ripening of Cavendish banana fruit, at median area (c...

BACKGROUND Volatile compounds of Cellina di Nardò and Ogliarola Barese, two typical Italian olive varieties, have been characterised at different ripening stages. Proton transfer reaction-time-of-flight-mass spectrometry (PTR-TOF-MS) was used for the first time on these fruits with the aim of characterising the volatile profile and, in the case of Ogliarola, the changes which may occur during t...

agricultural practices always need accurate information about occurrence of particular developmental stages. data from planting dates trials conducted over the kabotar-abad agricultural research station, isfahan during 2003-2009 were used to develop models for estimating developmental stages duration of sofea safflower variety. to model duration of each developmental stage, duration of each dev...

Transcriptional studies in relation to fruit ripening generally aim to identify the transcriptional states associated with physiological ripening stages and the transcriptional changes between stages within the ripening programme. In non-climacteric fruits such as grape, all ripening-related genes involved in this programme have not been identified, mainly due to the lack of mutants for compara...
