| description | Cocoa is one of the plantation commodities which its role is quite
important for the national economy, provide employment, income and foreign
exchange, thus cocoa has good prospects for development of cultivation.
However, the cultivation of cocoa on large scale is faced with the problem of
limitation of water, especially on marginal lands caused drought stress on cocoa.
In addition to drought, diseases may also lead to low productivity of cocoa.
Therefore, it is necessary arbuscular mycorrhizal fungi (AMF) to increase
resistance of cocoa to drought and diseases, because AMF has known helping
plant to water absorption and synthesis induction of defense compound against
pathogen infection. This research aimed to study the effect of AMF to the growth
and resistance of cocoa in the field on drought stress, as well as mechanism of
AMF to increase resistance against diseases. The experiment was carried out in
the field with the AMF inoculation and fertilization treatment using different
doses. Results showed the cocoa in field inoculated by AMF had better growth
than cocoa without inoculation and could avoid to drought stress by
maximalization of water absorption in minimum soil water condition so as to
maintain the relative water content of leaf at level of more than 70%. AMF
inoculation could decrease anthracnose leaf spot disease intensity caused by
Colletotrichum gloeosporioides amounted to 16.39%, caused to more equitable
lignification on cocoa root cortex tissue so as could increase cocoa defense to
drought stress, but had no direct effect on the accumulation of salicylic acid and
flavonoid in the cocoa. |
