ADVANTAGES
OF MULTIPLE ROOTSTOCK TECHNOLOGY |
|
|
|
 |
1.
Growth and development is accelerated or double in
comparison with single rootstock. Just as a man
could travel faster with two feet than one foot, a
plant could grow faster with double root systems. |
|
DOUBLE ROOTSTOCK. About
4.5 years ago, Dr. Rodolfo C. Undan and Bernardo
Dizon planted two grafted mango trees in a
not-so-favorable area at the Central Luzon State
University. One had single rootstock while the other
had two. Today, the one with double rootstock (right
being pointed to by Dr. Undan) is virtually double
in sized compared to the one with a single rootstock
being pointed by Dizon at left. |
|
| 2. The
tree becomes more prolific since it overcomes the
biennial (alternate) fruiting habit. Remember that
plants like mango produces heavy fruiting only after
every other year and if forced to bear fruits by
applying KNO3, the tree will have a short life span
as proven by what happen in Cebu, Zambales, Nueva
Ecija and Pangasinan. |

double rootstock 10-year old Thai lanzones
that bear fruit 60-kilos or more per year |
|
3. The tree will have more
root system that is essential to absorb the
nutrients (fertilizer) applied, thus minimizing
fertilizer losses due to evaporation and leaching.
4. The tree will also have better root anchorage
that enables the trees to resist strong winds and
other adverse conditions.
5. The gestation period (fruiting) of young trees is
shortened by one half of the normal waiting time.
Physiological maturity is also enhanced. A
fiver-year-old triple rootstock is equivalent to
8-10 year-old fruit tree that bears commercial
fruits. |

6. The tree will yield
early, therefore producing off-season quality fruits
which command higher price. The tree becomes
non-seasonal due to its reinforced nature.
7. Plants shall have lesser mortality in the field
and have more uniform growth. |
|
8. Faster propagation or
reproduction of the desired variety can be achieved.
9. Production or yield can be enhanced by up to 300%.
10. Plant's life span become longer which prolongs and
enhances productivity.
11. Imported varieties of seedlings like jackfruits and
guapple will become resistant to Phytophthora when double
rootstocked with the native variety. It has been observed
that latexless jackfruit, guapple and other imported
varieties grown from seeds died of phytophthora after 4-6
years. |
