Culturing excised root tips proves good model for early detection of salt stress
A study examined degrees of salt stress tolerance in species of the genus Prunus. Researchers studied the responses of isolated roots to salt stress in vitro in controlled culture conditions. Among other findings, the team discovered a significant inverse correlation between salt tolerance and starch accumulation in the maturation zone of root tips. The authors recommend the use of excised root cultures for rapid, early detection of salt stress tolerance in plants.
