and effect of their application on cyto-morphological
attributes of settlings of eleven genotypes of sugarcane (Saccharum
species hybrids) were studied. High concentrations of K, P, S, Fe, Mn, Zn and Cu contents and heavy metals were present in
crude spent wash as compared to the digested one. Root meristem
assay of settlings grown on crude and digested spent wash showed a detrimental
effect on mitotic efficiency and also induction of de novo chromosomal
aberrations viz. clump formation, chromosome stickiness, laggards and micronuclei
formation etc. higher number of chromosomal abnormalities as compared to those
of control conditions. Mitotic index of root-meristems
of different genotypes showed a decline of 62.65 to 100% in crude spent wash
treatment and 36.94 to 90.33% decline in digested spent wash treatments as
compared to the control. However, an improvement to the extent of 27.73% was
observed in the mitotic activity of root-meristems
treated with diluted spent wash (1:5 v/V with water). Inhibitory effects of
digested and crude spent wash were also visible on bud sprouting and settling
height, but 1:5 aqueous dilution of spent wash stimulated the early growth
attributes. Such beneficial effects of diluted spent wash were observed in most
of the sugarcane genotypes. Key words: Chromosome aberrations, Cytotoxicity,
