GERMINATION CAPACITY OF STORED POLLEN OF ABELMOSCHUS ESCULENTUS L. (MALVACEAE) AND THEIR MAINTENANCE SHAUKAT ALI KHAN AND ANJUM PERVEEN
Abstract: Pollen germination and viability of Abelmoschus esculentus L.,
(Malvaceae) upto 48 weeks was examined by "Hanging drop Technique"
in different concentration of sucrose and boric acid solutions (10-100%).
Viability under storage was determined by storing pollen in different
conditions, like refrigerator, freezer, in vacuum oven silica gel and
in organic solvents (Acetone, Benzene and chloroform). Pollen stored
at low temperature (-30oC - 200C) showed better germination as compared
to pollen stored at +4oC and in the fresh. Freeze dried pollen (-60oC)
showed the best of germination. Benzene showed more germination than
acetone and chloroform. Department of Botany University of Karachi, Karachi-75270, Pakisan. |
