Effects of foliar versus soil water application on ecophysiology, leaf anatomy and growth of pineapple
In the subtropics, pineapple [Anan- as comosus (L.) Merr.] can be grown in plastic green- houses to avoid low temperature, which is the main limiting factor to production outside of the tropics. Foliar water application and subsequent evaporative cooling can help avoid excessive leaf temperat...

| description |
In the subtropics, pineapple [Anan-
as comosus (L.) Merr.] can be grown in plastic green-
houses to avoid low temperature, which is the main
limiting factor to production outside of the tropics.
Foliar water application and subsequent evaporative
cooling can help avoid excessive leaf temperatures in
greenhouses during the hot seasons. The effects of fo-
liar versus soil irrigation on ecophysiology, leaf anat-
omy and leaf temperature of pineapple in protected
culture were tested to determine if the crop could re-
ceive sufficient irrigation to avoid plant stress solely
from misting the foliage. Materials and methods – Rel-
ative water content, relative chlorophyll content,
normalized difference vegetation index, membrane
stability, and cross sectional leaf anatomy were mea-
sured at periodic intervals. Pineapple plants were
subjected to soil irrigation, misting and drought.
At the beginning and at the end of the experiment, to-
tal leaf area, plant biomass and assimilate partition-
ing to leaves, stems and roots were measured. Results
and discussion – The normalized difference vegetation
index revealed differences among treatments after
fifteen days without irrigation. Pineapple plants en-
dured thirty days of water stress without membrane
damage. Plants irrigated by applying water only to
the leaves did not receive adequate water amounts
and showed similar signs of drought stress as those
of the non-irrigated treatment. Conclusion – Based on
ecophysiological, anatomical and growth responses,
soil water application alone is sufficient for avoiding
water stress and excessively high leaf temperatures
of pineapple plants grown in protected culture in
the subtropics, whereas only misting the leaves does
not provide |
