A. Effect of Tree Beheading on Growth Parameters
Prior to Grafting in Mango Top working
The data presented in Fig.1 revealed that the maximum
number sprouts per branch (26.31) and minimum days
required for stock shoot leaves turn to green (14.42) and ready to graft (52.73) were recorded in July beheading and
minimum number sprouts per branch (9.92) and maximum
days required for stock shoot leaves turn to green (25.30)
were observed in November beheading. The congenial
conditions i.e. optimal temperature and high humidity in
rainy season as compared to summer and winter season
might have led to faster chlorophyll development and
vegetative growth of stock, which resulted in less days to
sprouting of stock and stock shoot leaves turn to green i.e.
days to stock ready for grafting and more number of
spouts per branch, in July beheading. These results are in
accordance with,[6] and [12] in cashew.
B. Effect of Beheading/Grafting Month and Scion on
Days to Graft Sprout
Data depicting in Fig. 2 revealed that, early bud break
(15.64days) was noticed in August grafting i.e. May
beheading while, late sprouting (25.36days) was observed
in December grafting and September beheading. The
minimum mean days required for sprouting of grafts
recorded in Kesar (18.01) and was at par with Ratna
(18.19).The maximum mean days for graft sprouting were
required in Sindhu (18.91). The grafts of Sindhu made in
August required minimum days to sprout (15.06). The
maximum was recorded in Sindhu (26.96) in December.
This might be due to the variation in the genetic makeup,
which influences the histological and physiological
development of shoot. Similar finding were also observed
[1],[3],[7],[8] and [10] with respect to mango.
