Responses of Liriope platyphylla F.T. Wang & T. Tang and Ophiopogon japonicus (L.f.) Ker Gawl. seeds to desiccation
We tested the effects of desiccation on seed survival of two members of the Ruscaceae ( Liriope platyphylla and Ophiopogon japonicus). Desiccation from the initial high water contents (c. 60%) resulted in an initial increase in germination in O. japonicus but not
in L. platyphylla. However, desiccation to c. 5% water content resulted in complete viability loss in both species. The water contents at which 50% of viability was lost were c. 10 and 28% for L. platyphylla and O. japonicus respectively, suggesting that L. platyphylla
may exhibit type II seed storage behaviour while the response of O. japonicus is more consistent with the recalcitrant type III category.
