“…'Conference' pears are prone to internal browning, the incidence of which may increase during CA storage [67,68]. This study only partially supported those findings and the 1-MCP treatment seemed to more strongly promote the development of internal browning, which agreed with the observations already made by Hendges et al [63] during and after the storage of 'Alexander Lucas' pears. The possible reason for this is the loss of the antioxidant capacity and/or energy deficit caused by a reduction in the respiratory activity of fruit stored under CA.…”

“…Even though physiological disorders occur more rarely compared to fungal diseases, they are more difficult to contain by changing the composition of the atmosphere or applying 1-MCP [61][62][63]. The share of fruit affected by physiological disorders varied considerably between treatments, but it did not exceed 7.5% in any of the samples, which shows that physiological disorders are a minor cause of losses during storage.…”

Effect of Storage Conditions on Storability and Antioxidant Potential of Pears cv. ‘Conference’

Late pear cultivars, such as ‘Conference’, can be stored for a long period if kept in good storage conditions. A three-year study (2011–2013) compared the impact of six-month storage using four technologies—normal atmosphere, normal atmosphere + 1-methylcyclopropene (1-MCP), controlled atmosphere, and controlled atmosphere + 1-MCP—on the quality parameters of ‘Conference’ pears, such as mass loss, firmness, total soluble solids, acidity, antioxidant capacity, and the incidence of diseases and disorders. Additionally, the study analysed different storage conditions in terms of profitability, based on the market prices for pears in the seasons during which the pears were stored. The storage conditions had a very strong influence on the fruit quality parameters, and were found to affect most visibly the mass loss and the incidence of postharvest diseases and disorders. The storage of ‘Conference’ pears for 180 days in normal atmosphere is not economically viable, even if the fruit is subjected to 1-MCP treatment; at the same time, it is profitable to store ‘Conference’ pears in controlled atmosphere for the same period, no matter whether 1-MCP was applied or not.

“…The application of 1-MCP in CA-stored fruit further increased core browning incidence at both temperatures. Similar behavior was observed by HENDGES et al (2015HENDGES et al ( , 2018, who reported increased browning disorders in 'Alexander Lucas' pear when fruit were treated with 300 nL L -1 1-MCP and stored under CA (2.0 kPa O 2 plus <0.7 kPa CO 2 ). Saquet, Streif, and Almeida (2017) observed an increase in core browning in 'Rocha' pear treated with 300 nL L -1 1-MCP after 8.5 months storage.…”

The storage life of ‘Alexander Lucas’ pear is limited by the occurrence of internal storage disorders during controlled atmosphere (CA). 1-Methylcyclopropene (1-MCP) can be used to delay pear ripening, however, its interaction with CA conditions is not well understood. ‘Alexander Lucas’ fruit were treated with 1-MCP at 300 nL L-1 for 24 h in air at-0.5 or 1.0 °C before being stored. Fruit were kept at-0.5 or 1.0 °C in normal air or CA (2.0 kPa O2 plus <0.7 kPa CO2). After six months of storage, superficial scald did not develop in fruit. The highest incidence of flesh browning (72.2 %) was found in air-stored fruit at-0.5 °C without 1-MCP treatment. Storage in air at 1.0 °C plus 300 nL L-1 1-MCP produced 88.8 % of healthy fruit. In contrast, 1-MCP increased the incidence of flesh and core browning under CA conditions. 1-MCP and CA maintained greener skin color and higher titratable acidity. No significant differences were found for fruit firmness, total soluble solids and ascorbic acid content between the treatments. In conclusion, the quality of ‘Alexander Lucas’ pear was best maintained during six months storage under normal air at 1.0 °C combined with 300 nL L-1 1-MCP treatment.

“…Enzymes are proteins that catalyze chemical reactions and mediate virtually every biochemical reaction constituting life, so they are essential for the proper maintenance of any organism. Hendges et al (2015) evaluated corn oxidizing enzymes in drought periods, and did not observe changes in POD and APX activities. APX is one of the major enzymes involved in H 2 O 2 rapid elimination, as it has a high affinity for this molecule, even removing it at low concentrations (micromolar).…”

Does Allium sativum L. tolerate water deficit?

The objective of this work was to evaluate the effect on the physiological and biochemical aspects of garlic submitted to water deficit, knowing that the popular garlic Allium sativum L. is a culture known worldwide for its medicinal, culinary and ecological properties of agricultural pests. were constituted with water condition of 100; 75; 50 and 25% of pot capacity (CP). Three bulbs were planted per pot (5 L) containing Plantmax® substrate, irrigated every two days, according to pot capacity. The chlorophyll index was evaluated during the first and last week of greenhouse treatments. At 45 days after the treatments, the garlic plants were harvested to evaluate the physiological and biochemical parameters. Garlic plants showed to be sensitive to water deficit, resulting in lower leaf length and fresh biomass. Water stress induced the activity of the APX enzyme in the leaves and of the POD in the roots, as well as increase of proteins in the bulbilhos as biochemical mechanisms of adaptation.
