Short anaerobiosis period prior to cold storage alleviates bitter pit and superficial scald in Granny Smith apples.
BACKGROUND Californian Granny Smith apples are very susceptible to bitter pit (BP) and superficial scald symptoms that develop during cold storage. The main preventive means are diphenylamine dipping and/or gaseous application of the ethylene inhibitor 1-methylcylclopropene (1-MCP), which is effective against superficial scald but not against BP. This study investigated the efficacy of a non-ch...
متن کاملHypobaric storage removes scald-related volatiles during the low temperature induction of superficial scald of apples
‘Law Rome’ and ‘Granny Smith’ apples were stored hypobarically in air at 5 kPa total pressure and also in air or controlled atmosphere (CA) at 1.5 or 3% O2 with 0 or 3% CO2, for 8 months at 1°C. Fruit were placed under hypobaric storage immediately after harvest or after 0.5, 1, 2, 3, 4, 5 or 6 months storage in air at 1°C to determine the effects of delaying imposition of hypobaric storage on ...
متن کاملInitial low oxygen stress controls superficial scald of apples
The effectiveness of initial low oxygen stress (ILOS) to control apple scald without postharvest application of scald inhibitors and fungicides was investigated. Scald susceptible (‘Granny Smith’, ‘Law Rome’, ‘Red Delicious’) and not susceptible (‘Idared’) fruits were harvested preclimacterically and treated at 1°C with (1) ILOS pretreatment or (2) no pretreatment as control. Fruit were then st...

activity. This may lead to some error when calculating K,. Secondly, the potassium salt of the herbicide may produce some ion pairs. The calculation of Tz using line width is not very accurate and thus T2 measurements using the spinecho method may be preferred. The line-width changes in 2,4,5-T resonance peaks at a fixed BSA concentration in solutions of different pH are shown in Figure 4. The ...
متن کاملSELECTIVE CYCLIZATION OF 2-PROPARGYLTHIO-6-METHYL-PYRIMIDIN- 4(1 H)-ONE TO THIAZOLO [3,2-a] PYRIMIDIN 7-ONE
Selective transformation of 2-propargylthio-6-methyl-pyrimidin-4(1H)On e (2) to 3,5-dimethyl-7H-thiazolo [3,2-a] pyrimidin-7-one (3) is performed under the conditionof base catalysis . For elucidation of structure, palladium catalyzed cyclization reaction of (2) was carried out and the structures of the products were assigned (5) and (6). These compounds underwent isomerization to (3) and (4...
