Abstract:
This study was carried out under nursery condition in
Sudan University of Sciences and Technology, College of
Agricultural
Studies
Department
of
Horticulture,
to
investigate the effect of chemical and cultural treatments on
seed germination of Carica papaya L. in intact seeds and
without sarcotesta during the year 2011, germination
parameters.
Both intact and sarcotesta removed seeds were soaked in
either KNO3 , HSO4
against
control.
,
hot water, cold water and compared
Data

collected
for

percentage, germination rate, Seedling height, root length,
shoot and root fresh and dry weights
The results showed that soaking seed of removed sarcotesta
on
potassium
nitrate
gave
the
highest
germination
percentage, While the highest germination percentage for
intact seeds were recorded when seeds were treated with
hot water. The same pattern was observed for germination
rate. However, the highest number of leaves was recorded
for the cold water treatment in seeds without sarcotesta and
in controls and KNO3 treatments in intact seeds.
