Abstract

Abiotic elicitors methyl jasmonate (MJ), salicylic acid (SA) and paclobutrazol (PB) have shown significant improvement in total annatto pigment content of seeds of Bixa orellana that subjected to floral spray. Up to 2 and 1.5 to 2 folds of improvement in total annatto pigment content and % bixin levels was achieved through abiotic elicitors MJ, SA and PB spray respectively. Various growth regulators viz., indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), gibberellic acid (GA3), and 2,3,5-triiodobenzoic acid (TIBA) spray leads to moderate improvement in annatto pigment. Similarly chitin or chitosan spray resulted in 1.5 to 2 folds improvement in total annatto pigment and % bixin levels. All the three elicitors MJ, SA and PB were tested for three flowering seasons consecutively (2007, 2008, and 2009) and found consistence in response for annatto pigment augmentation. Hence, elicitor mediated augmentation of annatto pigment would have a wider scope for commercial purposes.
