- Abstract
Controlled environments were used to establish the base-line growth and to evaluate the photoperiodic response of two Tossa jute () cultivars. Fresh and dry weights of shoots and roots, leaf areas and stem lengths were much greater at long day (LD) 12·5, 11·5 than LD 11·5, 12·5 photoperiods for both cultivars. Root lengths were greater at LD 12·5, 11·5 initially but were longest at LD 11·5, 12·5 at 35 days from emergence. Mean relative growth rates (MRGR) were similar irrespective of photoperiod or cultivar but declined with plant age. The superior growth of cultivar ‘Yaya’ at LD 12·5, 11·5 was due to more growth in the first 7 days, while, for cultivar ‘Angbadu’ it was a combination of growth for 7 days, and higher MRGR up to 21 days. Stomatal density was greater at LD 12·5, 11·5 than LD 11·5, 12·5.
