“…Therefore, the expansion of the fruit flesh creates internal forces pulling on the pit. If great enough, this force will cause the pit to break in the weakest spot along the suture (Barcelon et al 1999). In fruits with shattered pits, the pits are broken in several places and the pit cavity may contain a gummy substance.…”

This study was carried out on 'Cardinal' peach (Prunus persica L. Batsch) between 2003 and 2005 in Bornova, in Izmir, Turkey to study the effects of irrigation, gibberellic acid (GA 3 ) and nitrogen (urea) on the physiological disorders split or shattered pit, double fruit and fruit quality. Irrigation treatments that were tested included 100% (no water stress) and 20% (water stress) replenishment of water depleted from the 100% replenishment treatment at 60 cm soil profile at 10-day intervals. GA 3 and nitrogen (urea) were applied to trees during the flower bud differentiation period at doses of 100 mg L(1 and 900 mg L(1 , respectively. Irrigation, nitrogen and gibberellic acid exerted a significant influence on fruit disorders and quality of peach cv. 'Cardinal'. Although the rate of double fruit was increased by water stress, GA 3 and nitrogen application decreased it. Irrigation (100%) during the final swell phase of fruit development accelerated the occurrence of split and shattered pit. Application of nitrogen and gibberellic acid or both to the trees with no water stress resulted in the lowest number of fruits with physiological disorders. Fruit quality characteristics, except for titratable acidity, were not significantly altered by the treatments.

“…In particular, there are many applications within biological sciences where we wish to detect weakly attenuating materials against similar background material. Qualitative and quantitative X-ray evaluations have been used by food-scientists and agriculturists, medical scientists, nanoparticle and material physicists, chemical analysts, airport security for non-destructive testing (Storm 1972, Zwiggelaar et al 1996, Schatzki et al 1997, Wallin and Haycock, 1998, Barcelon et al 1999a, b, Gibaud et al 2001, Gashaw et al 2004. The main matter/X-ray photon interactions that cause attenuation of X-rays passing through material objects take different forms, namely, photoelectric absorption, elastic (coherent/Rayleigh) scattering, and inelastic (incoherent/Compton) scattering.…”

Quality parameters of mango and potential of non-destructive techniques for their measurement — a review

The king of fruits "Mango" (Mangifera indica L.) is very nutritious and rich in carotenes. India produces about 50% of the total world's mango. Many researchers have reported the maturity indices and quality parameters for determination of harvesting time and eating quality. The methods currently used for determination of quality of mango are mostly based on the biochemical analysis, which leads to destruction of the fruits. Numerous works are being carried out to explore some non-destructive methods such as Near Infrared (NIR), Nuclear Magnetic Resonance (NMR), X-ray and Computed Tomography (CT), electronic nose, machine vision and ultrasound for quality determination of fruits. This paper deals with some recent work reported on quality parameters, harvesting and post-harvest treatments in relation to quality of mango fruits and reviews on some of the potential non-destructive techniques that can be explored for quality determination of mango cultivars.

“…Thus, using high resolution computed tomography Fromm et al (2001) detected and measured xylem water content and wood density in spruce and oak trees. Barcelon et al (1999) detected internal quality changes in peaches, and Lammertyn et al (2003a, b) investigated core breakdown disorders in ''Conference'' pears based on their mass density variations during storage. Kuroki et al (2004) obtained 3D spatial information about gas-filled intercellular spaces in sarcocarp tissue of cucumber fruit, and also investigated the structural changes of these spaces during storage.…”

The microstructure and the connectivity of the pore space are important variables for better understanding of the complex gas transport phenomena that occur in plant tissues. In this study, we present an experimental procedure for image acquisition and image processing to quantitatively characterize in 3D the pore space of apple tissues (Malus domestica Borkh.) for two cultivars (Jonagold and Braeburn) taken from the fleshy part of the cortex using X-ray computer microtomography. Preliminary sensitivity analyses were performed to determine the effect of the resolution and the volume size (REV, representative elementary volume analysis) on the computed porosity of apple samples. For comparison among cultivars, geometrical properties such as porosity, specific surface area, number of disconnected pore volumes and their distribution parameters were extracted and analyzed in triplicate based on the 3D skeletonization of the pore space (medial axis analysis). The results showed that microtomography provides a resolution at the micrometer level to quantitatively analyze and characterize the 3D topology of the pore space in apple tissue. The computed porosity was confirmed to be highly dependent of the resolution used, and the minimum REV of the cortical flesh of apple fruit was estimated to be 1.3 mm(3). Comparisons among the two cultivars using a resolution of 8.5 mum with a minimum REV cube showed that in spite of the complexity and variability of the pore space network observed in Jonagold and Braeburn apples, the extracted parameters from the medial axis were significantly different (P-value < 0.05). Medial axis parameters showed potential to differentiate the microstructure between the two evaluated apple cultivars.
