Morocco: Mitigation strategies against heat and radiation, a need common to several countries

The case of blueberries, or berries in general, are plants with little foliage and very exposed fruit, which is why they are susceptible to sunburn.

Heat stress is the series of irreversible damage to plant metabolism and development that high temperatures can cause. It is a complex phenomenon that involves the duration of the stress, the rate of increase and the maximum temperature reached. On the other hand, heat stress tolerance could be defined as the ability of a crop to grow and yield economically under high temperature conditions.

Excessive solar radiation affects crops and, just like people, causes burns and lesions of varying degrees of severity to the leaves, fruits, and stems.

Common factor

Sudden climate changes are being common in different regions of the world. In the last meeting in Guadalajara, the Mexican and Peruvian blueberry producers, together with those of Morocco, concluded that a common problem in their different realities was heat and scarcity of water, and this is probably a common factor in many other countries. producers.

In the case of blueberries, or berries in general, they are plants with little foliage and very exposed fruit, which is why they are susceptible to sunburn. In addition, the treatment of sunburns in the fruits must be preventive, because if damage occurs, it is irreparable.

Seminar

At the next meeting of the blueberry industry, in the context of the XXVIII International Blueberry Seminar To be held in the city of Agadir, in Morocco, this problem will be extensively addressed and will be in charge of one of the best specialists in the world in most of the physiological factors of blueberries, Dr. Jorge Retamales.

The researcher will develop the talk: “Effects of radiation and excess heat on blueberries: background and mitigation strategies”, in which he will face the problem and the strategic variants that can be developed to mitigate its impact.

Economic losses

We know that excessive heat causes damage to the development of the plant and the fruit, because the higher the heat there is more evaporation and less water absorption, which results in a weaker plant, with less dense foliage, which often in turn exposes the fruit to more radiation.

These factors produce mutations and irreversible damage to crops. If UV radiation indices between 8 and 10 are reached, damage includes superficial cell breakdown, dehydration and discoloration. Temperatures higher than 29°C also affect the color of the fruit, which reduces its commercial value due to the worsening of its appearance.

Definitely, sun or heat strokes cause millions in losses to world fruit growing, because in addition to major physiological problems, excessive heat and radiation reduce the yield and commercial quality of the fruit.

The next XXVIII International Blueberry Seminar It will be held 13 and September 14 in the halls of Hotel Les Dunes D'or Center De Congrès, in the city of Agadir, Morocco.
