Sporobolus stapfianus

October 19, 2017 cheeseman 0

Sporobolus stapfianus is a member of one of the largest and most important plant families, the Poaceae, but, alas, as Gaff et al. have put it, it is “obscure”. In this case, the desiccation tolerance is not apparent in all tissues, but is restricted to immature leaves of intact plants, and an as yet uncertain portion of the root system. Young leaves can tolerate drying to a comparable to the dryness of seeds for at least a year. Additional stress tolerances are to ionizing radiation, extreme temperatures and salinity to at least 215 mM NaCl.
