The effect of burial depth on the tuber viability of Bolboschoenus laticarpus and B. planiculmis under terrestrial conditions
Abstract:Adaptation to survival under drought stress was studied in two weedy Bolboschoenus species, Bolboschoenus laticarpus and B. planiculmis. Sprouting ability and viability/mortality ratio of underground tubers were studied in experimental cultivation at different burial depths. Drought strongly limited tuber sprouting. A considerable proportion of living dormant tubers was found to be stored in the soil especially at deeper soil depths. This may prevent the decay of aboveground shoots during dry periods and enable the renewal of the whole population after an unfavourable period. No strong differences in the response to dry conditions appeared between both studied species. Tubers of B. planiculmis appeared to be somewhat less viable compared to B. laticarpus.
