Kiwifruit [Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson, cv. "Hayward"] is classified as climacteric fruit and the initiation of endogenous ethylene production following harvest is induced by exogenous ethylene or chilling exposure. To understand the biological basis of this "dilemma," kiwifruit ripening responses were characterized at 20°C following treatments with exogenous ethy...

Although the alternative oxidase (AOX) has been proposed to play a role in fruit development, the function of AOX in fruit ripening is unclear. To gain further insight into the role of AOX in tomato fruit ripening, transgenic tomato plants 35S-AOX1a and 35S-AOX-RNAi were generated. Tomato plants with reduced LeAOX levels exhibited retarded ripening; reduced carotenoids, respiration, and ethylen...

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...

OBJECTIVE To compare clinical outcomes from outpatient with inpatient cervical prostaglandin E2 ripening for low risk labour induction. DESIGN Randomised controlled trial. SETTING Two tertiary hospitals in Adelaide, Australia. POPULATION Women with uncomplicated term pregnancies, scheduled for induction of labour for reasons of post-dates or for social reasons. METHODS Eight hundred and...

Plant embryos can survive years in a desiccated, quiescent state within seeds. In many species, seeds are dormant and unable to germinate at maturity. They acquire the capacity to germinate through a period of dry storage called after-ripening (AR), a biological process that occurs at 5-15% moisture when most metabolic processes cease. Because stored transcripts are among the first proteins tra...

The decay of seed dormancy during after-ripening is not well understood, but elucidation of the mechanisms involved may be important for developing strategies for modifying dormancy in crop species and, for example, addressing the problem of preharvest sprouting in cereals. We have studied the germination characteristics of barley (Hordeum vulgare 'Betzes') embryos, including a description of a...

The influence of ripening conditions (traditional and industrial) on oxidative and sensory stability of dry fermented sausage (Petrovská klobása), during 7 months of storage, was investigated. During the storage period the content of free fatty acids was significantly higher (P<0.05), while the content of malondialdehyde was significantly lower in the sausage subjected to traditional conditions...

Single warmings of ‘Cortland’, ‘Delicious’, ‘Granny Smith’ and ‘Pacific Rose’ apples to 20°C for 0–9 days after cold storage of 0–27 days were tested as a potential non-chemical method to control superficial scald development. Only in ‘Granny Smith’ was scald development reduced to commercially acceptable levels by warming, and even for this cultivar the response varied among growing regions. W...

After-ripening is the mechanism by which dormant seeds become nondormant during their dry storage after harvest. The absence of free water in mature seeds does not allow detectable metabolism; thus, the processes associated with dormancy release under these conditions are largely unknown. We show here that sunflower (Helianthus annuus) seed alleviation of dormancy during after-ripening is assoc...
