Studies on pollen viability of Cistanche deserticola / 中草药

ABSTRACT

Object To understand pollen life of Cistanche deserticola Y.C.Ma in natural conditions. Methods To determine pollen viability of C. deserticola in natural state by pollen germination method in vitro.Results The optimum conditions of C. deserticolapollen germination are pollens in primary flowering time and a culture medium with 0.6% agar + 10% sucrose + 0.1% boric acid, cultured in 25 ℃, which is benefit to pollen germination and pollen tube growth; low temperature (4 ℃) is benefit to pollen short-dated storage and can prolong pollen life. Conclusion The study provides a theoretical basis for conserving better seed resources and artificial cultivating by pollen of C. deserticola.
