Mango Tree
Mangifera indica, locally known as mango or mangga, is an evergreen tree known for its green
and ripe fruits. It is one of the most cultivated trees in tropical regions, such as the Philippines,
where it can be found in nearly all backyards and farms.
Leaf structures vary in size and shape but are often long, lanceolate, or elliptical. Leaves have
long stalks or petioles and are leathery in texture. Leaves have dense venation that supports
efficient transportation and distribution of nutrients and water. Xylem, a vascular tissue,
conducts the movement of water from the roots throughout the tree. During drought, the
stomata close to regulate gas exchange and water loss.
Respiration in mango trees produces energy that is vital for many cellular activities which
eventually aid in the growth of trees, most importantly in the flushes of leaves and
development of fruits. They best grow in regions that have distinct dry and wet cycles.
Vegetative growth occurs in the wet season, where it receives a high amount of water that
supports the flushes of leaves and builds essential water reserves. Conversely, reproductive
development happens during dry periods, which signals the production of flowers instead of
leaves.
Mango trees are highly tolerant of drought that can last up to 8 months. This is because they
possess many adaptive features, such as deep sink roots, tough leaves with thick cuticles for
nutrient retention and recycling, resin ducts to reduce water loss, and irregular fruiting patterns,
all of which depend on resource availability.
Mango trees are not just highly tolerant of drought, but they also exhibit a remarkable capacity
to withstand flooding. While deep taproots and leathery leaves help mango trees survive
prolonged dry spells, certain trees can manage medium-term flooding (lasting 10–50 days) by
developing hypertrophic, or swollen, lenticels on the trunk just above the waterline. These
lenticels play a crucial role in removing toxic by-products of anaerobic metabolism, thus
enabling the trees to cope with low-oxygen conditions during submersion. However, mango
trees that do not develop these specialized lenticels typically perish after only 4–5 days of
inundation. Meanwhile, the presence of hypotrophic lenticels in potted seedlings is a sign of
overwatering or unsuitable growing media, emphasizing the importance of proper root
aeration. This dual tolerance for both drought and flood conditions highlights the mango tree’s
remarkable adaptability to changing environments.
