3-5-4 DISCUSSION
First exLerimont. In this experiment there was no significant
difference in the growth of the different Termitomyceg cultures, and
there was no significant difference in growth on the 2 media (Table
395*1)o There was a significant Interaction between species and
media showing that the response to the two media was not the same
for each species*
The cultures from the 2 Kicrotermes, species both grew slightly
larger on the selective mediumq whereas the cultures from the 12
OdontotermesIspecies and Anciatrotermes cavithorax all produced most
growth on the SF medium* OD 42 and AN 53 produced significantly
greater growth on the SF medium than cultures fren the other species&
On the selective medium the culture from OD 54 was significantly
smaller than all the other cultures.
Second exl2eriment. In this experiment there was no significant
difference between the growth an the 2 media, but there van a
significant difference between the growth of cultures from different
Hicrotermen species at the 5% level of significance (Table 3*5.2).
There was a significant Interaction between species and media showing
that the response to the 2 media was not the same for each species.
The culture from Mcrotermes bps P grow significantly bigger than all
tho others, and that from op. D was significantly smaller than all
except that from Hicrot_crmes, spo Zo Three out of the 7 cultures (from
Microterme'S app# As L) and D) were bigger on the selective medium*
Initially growth was greatest on the SP medium but after the first
week the growth increased at a faster rate on the selective medium*
on tjie
103F medium the culture from spe R was significantly bigger than
all the rests with that from D significantly smaller than the rest
except for the culture from op* Zo
