Summary Of Argentina's Pear And Apple Season
- May 29, 2018 -

This season's climate conditions were good. As a result, there was a good flowering in the Upper Valley region, where cold accumulation was slow and temperatures were optimal. There was a slight delay in the flowering of pears at the end of the season because of the cool weather that stopped their development, according to a newsletter published by the Central Market in Argentina, CMCBA. 


This cold weather didn't delay the flowering of apple trees, which usually starts a week after the pears, so their flowering dates remained practically as normal. The season started when it was supposed to, unlike the last 3 seasons when there was both early and late flowering.



Williams Pear

The weather conditions were less favorable for the Williams pear and may have affected sizes. There's been a generalized delay to the start of the harvest due to the low calibres. In the first harvests, producers observed damages to the fruits' skin, in addition to frictions and scratches caused by the climatic conditions of the first weeks of January. The high temperatures led to a greater dehydration and immaturity of the fruits. This situation gradually improved in the following weeks.


The delay in harvesting affects the conservation of the fruit. The main limitation is determined by the harvest dates that are divided into 3 phases: from January 23 to 28, where the optimum conditions for long conservation of the fruit are given; from January 29 to February 3, when the conservation conditions are shorter; and from February 3 onwards, when they have a low conservation capacity, i.e. less than 60 days.


The main problems of the late harvests are the rapid loss of green color in conservation, softening, and the appearance of internal decay. These problems can occur both in cold storage and in the market.


Red Delicious Apple

Producers also detected some problems in apples in some areas due to different factors, such as the vigor of the buds, an accumulation of cold and heat, and due to the cool and rainy period that occurred after flowering, when there were average temperatures below 12° C and precipitations that reduce the amount of pollen and bee activity.


In addition, every second year plant production decreases. Thus, there was a decrease in the production of apples, especially of the Red Delicious variety, that range between 10 and 40%, depending on the case.


As of mid-March, the variety's maturity indexes showed that they could have a lower storage capacity, so producers were told they should start segregating lots according to maturity stage and shorter periods of conservation.


Extending the conservation period above the possibilities of the fruit can lead to a loss of firmness of the fruit, lack of crispness, etc., in addition to problems related to browning, internal decay of the pulp, and rottenness.
