| Summary: | Certified soybean seed which were circulated in the market only guarantee the value of
germination and purity of the seed. Seed�s healthy test was not included in certification test.
The infected seed could influence the plant�s growth and become the source of infection in
the field. Seed treatment has become a part of practice in order to maintain the quality of
the seed. Seed treatment is used to remove the source of seed infection, protects the seeds
from pathogens and pests, and improve seed germination. This research aimed to know the
effect of heat treatment to germination and health of the seed, and to determine the proper
heat treatment to eliminate pathogen without decreasing the germination of seed. This
research was conducted by hot water treatment and dry heat treatment of soybean seed at
different temperature and time. Both of the treatment were observed separately. This
research used a 3x3 factorial design. The first factor was temperature and the second one
was the length of time. Hot water treatment was done at various temperature of 45, 55, and
65 ° C with length of time 10, 20, and 30 minutes. Dry heat treatment was also done at
three different temperatures at 50, 60, and 70 ° C with the length of time 1,2, and 3 hours.
Control treatment was done by planting seeds on top of filter paper in petridish and directly
in soil without heat treatment. Each treatment was replied 4 times. To compare the hot
water treatment and the dry heat treatment with control, T test is used. Hot water treatment
at 45 ° C for 10 minutes is the appropriate heat treatment due to the short time of this
treatment could eliminate 9 types of fungal colonies which were grown without reducing
germination of the seed. The results showed that the heat treatment at 60-70 ° C can
decrease germination of the seed. |
