“…In addition, our results also coincide with research reported in New Zealand where those results showed an increase in the number of lenticel lesions when fruit was subjected to mechanical damage [12]. Lenticel damage whose etiology has not been clear established yet, has been reported to be significant in avocado, increasing during prolonged storage and affecting external quality [16,32].…”

“…Our results suggest that Hass avocado fruit harvests should be carried out under an appropriately harvesting system to control the development of lenticel damage in the fruit after harvest and during prolonged storage. Previous works have reported improper handling of the fruit not only at harvest, but during handling and storage that incurred in fruit subjected to friction may exacerbate lenticel damage [16,32].…”

Black spot corresponds to a physiological disorder of the type of oxidative stress that occurs after the prolonged postharvest storage of Persea americana Mill. cv. Hass fruit. Industry tends to confuse this disorder with pathogen attack (Colletotrichum gloeosporioides), chilling injury, mechanical damage during harvest and transport or lenticel damage. The main objectives of this research were: (i) to develop a method to assess and differentiate lenticel damage and black spot and (ii) to study the correlation between mechanical damage and lenticel damage on the development of black spot. Avocado fruits from different orchards were evaluated at two sampling times using different harvesting systems (conventional and appropriate) and at two times of the day (a.m. or p.m.). Here, we report a method based on image analysis to differentiate and quantify lenticel damage and black spot disorder. In addition, the results show that conventional harvest increased lenticel damage and lenticel damage did not correlate with black spot development but correlated with increased weight loss during prolonged postharvest storage. These results have important commercial implications since the appropriate harvesting of avocado cv. Hass would not only control the incidence of lenticel damage, which would be an advantage in terms of external quality, but also reduce weight loss during transport to distant markets.

“…The commercial application of early CA in avocado packaging suggests that shelf life could be extended by 2 d based on firmness. Cold damage during storage of 'Hass' avocado can also be controlled through pre-conditioning (pulp hydro-cooling to 6 • C) and waxing [40]. The hydrocooling pre-treatment alone cannot effectively prevent lenticelosis, but in combination with waxing creates a three-fold reduction of internal damage and retarded fruit colour break [40].…”

Extension of Avocado Fruit Postharvest Quality Using Non-Chemical Treatments

Developing postharvest management techniques using environmentally friendly and non-chemical approaches is key to extending the shelf life of avocados in a safer and health conscious manner. Avocados are prone to postharvest deterioration caused by mechanical damage, chilling injury, soft landing, uneven ripening and decay. Among the different cultivars of avocados commercially grown worldwide, the ‘Hass’ variety continues to be the most predominant due to its nutty flavour and functional properties. Most of the literature on postharvest decay and disorders affecting avocado fruit quality during storage and marketing is dedicated to the Hass avocado. Some of these postharvest problems are unique to the ‘Hass’ avocado can possibly be controlled by simply investing more research into other cultivars. These postharvest losses can be significantly controlled using eco-friendly technologies, such as modified atmosphere, physical heat treatments and most importantly investing in natural biodegradable products with naturally inherent antimicrobial properties. Thus, this review includes the recent research-based information on the use of non-chemical treatments on the improvement of fruit health and quality.

“…Plant cold acclimation is associated with multiple physiological modifications participating in membrane stabilization and ROS reduction to maintain cellular homeostasis and prevent low temperature-induced oxidative injuries 18 . Studies have shown that pre-storage cold acclimation treatments can reduce chilling injury of harvested fruit for cucumber 19 , citrus 20 , zucchini 21 , avocado 22 , loquat 23 and mango 24 . Production of protective compounds such as sorbitol could act as a cryoprotectant to promote directly membrane stabilization as demonstrated in transgenic Arabidopsis 7 .…”

Superficial scald is one of the most serious postharvest physiological disorders that can affect apples after a prolonged cold storage period. This study investigated the impact of pre-and post-harvest climatic variations on superficial scald in a susceptible apple cultivar. Fruit batches with contrasting phenotypes for superficial scald incidence were identified among several years of "Granny Smith" fruit production. The "low scald" year pre-harvest climate was characterised by a warm period followed by a sudden decrease in temperature, playing the part of an in vivo acclimation to cold storage. This was associated with many abiotic stress responsive genes which were induced in fruit peel. In particular 48 Heat Shock Proteins (HSPs) and 5 Heat Shock transcription Factors (HSFs) were strongly induced at harvest when scald incidence was low. For "high scald" year, a post-harvest acclimation of 1 week was efficient in reducing scald incidence. Expression profiles of stress related genes were affected by the acclimation treatment and indicate fruit physiological adaptations to cold storage. The identified stressresponsive genes, and in particular HSPs, could be useful indicators of the fruit physiological status to predict the risk of scald occurrence as early as harvest.
