Why bending is done in guava?(General Horticulture)
The main object is to reduce dominance of polarity. In local varieties buds at top are
sprout and the buds at lower side of shoot are failed to sprout. This behaviour of apical buds
to dominate the buds situated on the lower side is termed as apical dominance of polarity
To break this apical dominance and to bring all buds to one level and to give equal
chance to every bud to sprout. The erect growing branches are bend and made horizontal,
when the shoots or branches is made horizontal more auxin accumulates on the lower side of
the shoot, this leads sprouting of buds. This operation is done only in erect growing varieties.
‘Sardar’ guava is naturally horizontal; its brandus do not required any bending.
