expansion ( Bacon et al., 1998 ; Van Volkenburgh, 1999 ). Thus, the overall effect of ABA is shoot growth suppression and an increase in root-to-shoot ratio. The potential of ABA as a growth retardant has been studied for some vegetable transplants. For

fragrance, improving resistance to environmental stresses will be one of the goals in future breeding and biotech programs ( Pemberton, 2003 ). Plants have developed various mechanisms to tolerate drought stress such as altered root to shoot ratio, smaller

cowpeat. However, root dry weights were not significantly different across the seven substrates. As a result, root-to-shoot ratios of seedlings produced from the control substrate (C-1) were significantly greater than those germinated from the substrates

root-to-shoot ratio was higher with feather meal than with fish emulsion ( Fig. 2A ), higher with sawdust or compost + sawdust than with weed mat ( Fig. 2B ), and higher in ‘Duke’ than in ‘Liberty’ ( Fig. 2C ). Contrast analysis indicated that the ratio
