Shrivastava, A.K., Srivastava, D.C., Solomon, S., Srivastava, M.K., & Singh, I. 2003 Physiological characters imparting resistance to biotic and abiotic stresses in sugarcane.. Sugar Tech 5(3): 105-120.
Notes: Sugarcane genotypes have been known to possess differential resistance to biotic and abiotic stresses which adversely affect sugarcane and sugar productivity per se. This review is an effort to elucidate physiological characteristics imparting resistance/tolerance to biotic stresses including insect pests (such as Pseudococcidae) and diseases and abiotic stresses such as drought and waterlogging. Certain physiological attributes such as tight leaf sheaths imparted multiple resistance against internode borer, pyrilla and lygaeid bugs; aged canes imparted resistance to mealybugs, eye spot and rust diseases and waterlogged conditions. Similarly, polyphenol oxidase [catechol oxidase] activity related to resistance against red rot and waterlogged conditions. Resistance to certain stresses is also confounded with a number of other morphological or physiological characteristics. These characteristics could be considered as physiological basis for resistance to biotic and abiotic stresses and also used as a marker for marker-assisted selection in directed breeding programmes.
