“…The resonance arising due to citrate was first observed at stage IV and increased sharply until maturity of the fruits. Similar increase in the levels of citrate and malate has been reported in developing fruits of strawberry (Iannetta et al, 2004).…”

“…With either of these approaches, there is a risk that the measurements collated do not reflect the ripening processes that occur in planta. This may be due to the removal of important growth promoters as a result of fruit detachment and/or dissection or due to the release of components in fruit extracts that inhibit enzyme activities or bind protein or metabolites (Iannetta et al 2004, Souleyre et al 2004).…”

Laser photoacoustic spectroscopy continuously quantified the ethylene (C2H4) produced by strawberry flowers and fruits developing in planta. C2H4 was first detected as flower buds opened and exhibited diurnal oscillations (to approximately 200 pl flower−1 h−1) before petal abscission. Exogenous application of silver thiosulphate (STS) to detached flowers inhibited petal abscission and flower senescence. In fruit, C2H4 production was maintained at a ‘low level’ (10–60 pl fruit−1 h−1) until fruit expanded when levels increased in a diurnal pattern (to 200 pl fruit−1 h−1). After expansion, C2H4 production declined to a low level until fruit attained the red‐ripe stage for at least 24 h. After this time, C2H4 levels increased linearly (no diurnal fluctuation) to approximately 1 nL fruit−1 h−1. Twenty‐four hours after the re‐initiation of C2H4 production by red fruit, CO2 levels increased approximately three‐fold, indicative of a respiratory climacteric. STS applied to fruits developing in planta and dissected fruit parts ex situ established that C2H4 production is regulated by negative feedback until fruits had expanded. The C2H4 produced by red‐ripe fruit was regulated by positive feedback. Anti‐1‐amino‐cyclopropane‐1‐carboxylic acid oxidase IgG localization identified immunoreactive antigens of 40 and 30 kDa (Mr) within the fruit achenes of expanding and red‐ripe fruit. Analysis of dissected fruit showed that seed C2H4 accounts for 50% the C2H4 that is detectable from ripe fruit.

ABSTRACT. In this experiment, the test materials were 'Red Fuji' apple trees grafted onto three interstocks (No. 53, No. 111, and No. 236), which were chosen from SH40 seeding interstocks. The content of malic acid, the enzyme activities, and the expression of genes related to malic acid metabolism were determined during fruit development.The results showed that malic acid content in the ripe fruit on interstock No. 53 was higher than that in the interstock No. 111 fruit. The malate dehydrogenase (NAD-MDH) activity in apples on interstock No. 53 was highest on Day 30, Day 100, and Day 160 after bloom, and the malic enzyme (NADP-ME) activity in apples on interstock No. 111 was higher than in the interstock No. acid in the ripe apples.There was a positive correlation between the relative expression of phosphoenolpyruvate carboxylase (PEPC) and the malic acid content of the fruit, and the content of malic acid in the apples was affected by the PEPC activity during the early developmental stage.
