Israeli researchers find the perfect temperature to save avocados
The rise in temperature due to global warming has led to a shortage of the popular avocado plant, driving researchers to seek out the optimal conditions for its survival.

The demand for avocados
is skyrocketing globally, but the rise in temperature due to global
warming has led to a shortage of the popular plant, which is considered
tropical and needs a certain temperature and a lot of water to survive.
Researchers at Israel's MIGAL Institute
and Or Shapira Volcani Research Institute have found the temperature
threshold to keep young Hass avocados, which accounts for 85% of global
avocado commerce, plant leaves healthy.
Young
potted plants were subjected to different temperature gradients in a
controlled-climate chamber, according to the study. The results showed
that the plants were gradually damaged from 49 °C, until severely and
irreversibly damaged at 53 °C. Thus, implying that the heat stress
threshold for young Hass avocado plants is between 49–51 °C under low
light intensity.

The study warned that extreme heat from global warming could lead
to global food insecurity impacting more than avocados, including fruit
trees and citrus.
The research was published the scientific journal Plants.
