“…Results for rates of respiration and ethylene production, individual sugar concentrations, and total protein concentrations during ripening were similar to those obtained previously from the same orchards in 2007 (Blakey et al, 2012), so only those results for fruit taken immediately after storage are presented for these parameters.…”

“…Ethylene concentrations were measured using a gas chromatograph (GC) fitted with a flame ionisation detector (DANI 1000; DANI Instruments, Monzese, Italy) according to Blakey et al (2012). The GC was fitted with a 2 m ϫ 3 mm stainless steel column packed with an alumina-F1 60/80 stationary phase.…”

“…The output of CO 2 from individual fruit was measured using an infrared gas analyser (EGM-1; PP Systems, Hitchin, UK) in a 1.0 l container after 15 min, according to Blakey et al (2012). The CO 2 concentration in the headspace was converted to a rate of respiration taking into account the fruit FW, fruit volume, the free space in the jar, and the ambient CO 2 concentration, and was expressed in mmol CO 2 kg Ϫ1 FW h Ϫ1 .…”

“…The proile of acetogenins in the peel, seed and pulp of avocado fruits has been determined to obtain a chemotaxonomic model using a linear discriminant analysis [53]. Also, changes of sugars, total protein and oil in 'Hass' avocado have been determined using GC-FID and LC [54]. On the other hand, important proteins from the pulp have been identiied through the use of nano-LC-MS/MS [55].…”

Metabolomics is a study through can be obtain a beter understanding of the complexity of the biological systems, through the chemical composition and relations with the physiology of the plant. The literature describes a lot of information on this support in areas of medicinal plants, chemosystematics, adulteration of plants, etc., but it is scarce in agriculture. At present, agriculture plays a crucial role in human beings. The demand of foods has increased due to the continuous increase in the population, and this requires an increase in the production of crops, besides the crops being afected by the climatic change, atack of pest and diseases and resistance to a conventional agrochemicals. At present, scientists are doing some practices or studies of genetic improvement of crops to increase their production and avoid the problems pointed out. It is an important part of the genomic studies; the results could be the basis for a genetic improvement based on the chemical composition of the crops, and in the metabolomics studies represent a crucial role in their quality for human consumption. The aim of the chapter is to review the literature from 10 years behind emphasizing the importance of metabolomics in crops of economic and feed value.

“…Weekly removal of vegetative buds during blooming and fruit set significantly reduces the percentage of fruit fall. Nonetheless, fruit at harvest come from different moments of fruit set, and these differences in fruit age at harvest will be evidenced as ripening heterogeneity during the postharvest period [51].…”

-Introduction. 'Hass' is the main avocado cultivar commercialized worldwide. The extended flowering period, very low percentage of fruit set and inability to ripen on the tree renders the fruit heterogeneous and unpredictable during postharvest management. The "triggered" and "ready-to-eat" growing markets for 'Hass' avocados are affected by the variable postharvest ripening or ripening heterogeneity which creates severe logistical problems for marketers and inconsistent quality delivery to consumers. Synthesis. The dry matter content, the current avocado harvest index that correlates very well with oil content, has been extensively used to harvest 'Hass' avocados to comply with the minimum standards to guarantee consumer satisfaction. However, previous work and empirical experience demonstrate that dry matter does not correlate on a fruit-to-fruit basis with time to reach edible ripeness. Thus, avocados of very different ages are harvested from individual trees, resulting in heterogeneous postharvest ripening of fruit within a specific batch. Several preharvest factors related to environmental and growing conditions and crop management as well as postharvest technology strategies influence the observed variability of postharvest ripening. Conclusion. Modern approaches based on studying the composition of individual fruits displaying contrasting postharvest ripening behavior, combined with non-destructive phenotyping techniques, seem to offer practical solutions for the fresh supply chain of avocados to sort fruit based on their ripening capacity.Keywords: avocado / Persea americana / fruit quality / ripening stage / preharvest management / secondary metabolites / non-destructive analysis Résumé -Facteurs associés à l'hétérogénéité du mûrissement post-récolte des avocats (Persea americana Mill cv. Hass). Introduction. Le 'Hass' est la principale variété d'avocat commercialisée dans le monde. Sa période de floraison prolongée, son très faible pourcentage de nouaison et son incapacité à mûrir sur l'arbre en font un fruit hétéro-gène et imprévisible à gérer après récolte. Le marché croissant des avocats 'Hass' « déclenchés » et « prêts-à-manger » est affecté par la variabilité ou l'hétérogénéité du mûrissement post-récolte, ce qui crée de sérieux problèmes logistiques aux spécialistes du marketing et offre une prestation de qualité inégale aux consommateurs. Synthèse. La teneur en matière sèche, l'actuel indice de récolte des avocats qui correspond parfaitement à la teneur en huile du fruit, a été largement utilisé pour récolter les avocats 'Hass' en conformité avec les normes minimales de garantie de satisfaction des consommateurs. Toutefois, des travaux antérieurs et l'expérience empirique démontrent que la matière sèche ne correspond pas à un paramètre sur lequel se baser d'un fruit à l'autre pour estimer la durée jusqu'au fruit mûr prêt à manger. Ainsi, pour des fruits d'âge très différents récoltés arbre par arbre, il en résulte une hétérogénéité du mûrisse-ment des fruits après récolte dans chaque lo...
