Towards flexible management of postharvest variation in fruit firmness of three apple cultivars

Developmental variation of phenolic compounds in fruit tissue of two apple cultivars.

BACKGROUND Qualitative and quantitative analyses of 'Zonouz' and 'Gala' apples phenolic compounds were accomplished by HPLC. MATERIAL AND METHODS Samples for phenolics study were taken at three different growing stages [1 - fruit early growing stage 2 - mid-stage of fruit development (80 days after full bloom) 3 - during commercial harvest time]. RESULTS The results showed qualitative diffe...

Evaluation the Preharvest Application of Iron and Nitrogen on Some Qualitative Characteristics of Two Apple Cultivars during Cold Storage

Apple is one of the most important fruits in temperate zones with a long post-harvest life during cold storage. A factorial experiment, in a randomized completely block design was used to investigate the preharvest application of Iron (0, 500 and 1000 mg Fe-EDDHA per tree) and nitrogen (0, 48 and 96 g ammonium nitrate per tree( on some postharvest qualitative characteristics in "Red spur" and "...

Analysis of spatially resolved hyperspectral scattering images for assessing apple fruit firmness and soluble solids content

Hyperspectral scattering is a promising technique for nondestructive sensing of multiple quality attributes of apple fruit. This research evaluated nd compared different mathematical models for describing the hyperspectral scattering profiles over the spectral region between 450 nm and 000 nm in order to select an optimal model for predicting fruit firmness and soluble solids content (SSC) of ‘...

Multispectral imaging for predicting firmness and soluble solids content of apple fruit

Firmness and soluble solids content (SSC) are important quality attributes for apples and many other fresh fruits. This research investigated the feasibility of using multispectral imaging to quantify light backscattering profiles from apple fruit for predicting firmness and SSC. Spectral images of the backscattering of light at the fruit surface, which were generated from a focused broadband b...
