Popis:	The tillering process which determines the field stand as well as the ultimate millable canes at harvest is regulated by several internal factors viz., hormones, nature of the genotypes and environment prevailing during tillering. The senescence percentage of tillers differs based on their time of production. Tillers produced beyond 100 days after planting are prone for senescence. The indole acetic acid (IAA), Gibberellic acid (GA) and abscissic acid (ABA) content varied in live and senescing tillers with senescing tillers recording high level of ABA, while in live tillers it was not detected. Higher cell membrane injury, increased lipid peroxidation product (Malondialdehyde) and decreased ascorbic acid content implied the catabolic activity in the senescing tillers resulting in complete collapse and death of the tillers prematurely.
