'Jelly seed

' affects the market prospects, appears to be related to reduced
internal calcium allocation to fruits under the influence of high tempera-
ture holds ground in light of the observations of Batten et al. (1988) as its
incidence increased in late harvested fruits exposed to high temperatures
(T
max
>40 °C). This view is also substantiated by the results of Singh et al.
(2006) that highlighted the factors of late harvesting after a spell of rains,
and association of fruit transpiration with internal break down in '

in combination with potassium sulfate (1.0%) along with soil application
of borax (150-250 g per tree) in October-November, a month before har-
vesting of fruits controlled this disorder.

CONCLUSIONS
The flowering in mango whether in regular or irregular bearing varieties
is the result of hormonal interpolations within the plant system under the
strong influence of environmental factors especially the T
Tmin
though other
components could also impact adversely the mango phenophases, about
which sufficient quantified data are not available This environmental vari-
able has been studied widely in mango by many researchers. Other envi-
ronmental cues viz., light, water, sunshine hours, wind, salinity though
