INDUKSI KETAHANAN STRUKTURAL PHALAENOPSIS AMABILIS TERHADAP FUSARIUM SP. DENGAN RHIZOCTONIA MIKORIZA

Abstract

800x600 Phalaenopsis amabilis or better known moon orchids as germplasm in the slopes of Mount Merapi . The existence of this orchid on the wane since the attacks of pathogenic fungi . Fusarium solani is the most attacking pathogen Phalaenopsis sp. orchid ( Chung et al ., 2011) compared to other pathogenic fungi . Attack of Fusarium sp . will cause rot and yellow colored leaves . Until now there has been known as a biological control against Fusarium sp . Based on previous studies , which are mycorrhizal fungi Binucleate Rhizoctonia ( BNR) has the ability to inhibit the growth of Fusarium sp. on horticultural crops , but has not been tried on orchids . Expected prainokulasi mycorrhizal Binucleate Rhizoctonia spp . ( BNR) is the orchid seedlings , can inhibit subsequent infection by Fusarium sp . This mechanism is known as a form of induced resistance ( induced resistance ). The mechanism of induced resistance in plants such as orchids like lignification structural resistance mechanisms and the formation of the structure of the peloton as a condition of their association with Rhizoctonia orchid mycorrhiza . Results platoon formation in Sleman more inetsif disbanding in Surakarta . Formation of a structure lignifikasi in Sleman thicker than the in Surakarta . We hope this research can later be used as a model as a method of induced resistance in other epiphytic orchid plants in Indonesia .
