| description | Rice blast disease caused by Pyricularia oryzae is the most devastative disease. The alternative in rice blast disease management
using foliar silicon (Si) application is gaining attention. The mechanism underlying defense-related enzyme induced through
foliar Si application is still scarce. This research aimed to elucidate the bio-efficacy of foliar Si in inducing defense-related
enzyme activity against P. oryzae in two aerobic rice cultivars: MR219-4 (blast-partially resistant) and MARDI Aerob 1
(resistant). Calcium silicate at 9 mg/L was foliar-sprayed and the disease severity index was evaluated and transformed to the
area under disease progress curves (AUDPC). Foliar Si application significantly reduced rice blast disease severities in both
cultivars tested. The AUDPC was reduced to 96.57 (MR219-4) and 21.90 (MARDI Aerob 1), from 148.57 (MR219-4) and
53.73 (MARDI Aerob 1). Plant defense-related enzymes: peroxidase (PO), polyphenol oxidases (PPO), and phenylalanine
ammonia-lyase (PAL) were increased and might be associated to increase resistance. Also, there was a significant interaction
(p=0.003) between rice cultivar and treatment to Si content in rice leaf. Thus, foliar application of Si in rice seedling underlined
the important role of Si as a modulator in influencing plant defense-related enzymes with interacting with other stress signaling
pathways leading to induce resistance. |
