TY - CONF T1 - Anatomical Structures of Leaf Surface and Physiological Properties of Synedrella nodiflora related to Resistance against Fomesa  T2 - Internatiomal Symposium on Indonesian Biodiversity Y1 - 2013 A1 - Agus Hery Susanto A1 - Murni Dwiati KW - Fomesafen KW - resistance KW - Synedrella nodiflora AB - Fomesafen is one of widely used herbicides to control Synedrella nodiflora, a broad-leaf weed species commonly found in several estates with potential of causing serious problems in crop productivity. After 30 years of use, however, resistance against this herbicide in waterhemp was reported. Here we describe anatomical structures of leaf surface and physiological properties of S. nodiflora associated with its resistance against Fomesafen. The results showed that anatomical structures of leaf surface in resistant S. nodiflora, particularly the number of trichomes and stomata at leaf lower surface, correlate significantly to Fomesafen absorption, while it is not the case in susceptible wildtype. In general, resistant S. nodiflora shows better plant vigor than it is in susceptible wildtype JF - Internatiomal Symposium on Indonesian Biodiversity PB - Faculty of Biology, Jenderal Soedirman University CY - Purwokerto, Central Java, Indonesia ER -
