Sugarbeet Pollen Germination in Vitro

Journal of Sugarbeet Research, 1988
Factors affecting in vitro germination of sugarbeet (Beta vulgaris L.) pollen were investigated to provide improved methods of testing pollen viability. Pollen germinated most frequently and consistently in a liq­ uid medium (pH 5.5, 100 ppm H3B03, 100 ppm Ca(N03)2 • 4H20, and 3.2 x lOs ppm sucrose in dis­ tilled water) at 23 C for 24 hours.

IN VITRO POLLEN GERMINATION OF PEACH CULTIVARS

Acta Horticulturae, 2007
In vitro pollen germination was determined in five peach cultivars, Prunus prsica (L.) Batsch cv. Dixired, Redheaven, Gloheaven, Suncrest and Summerset, Different sucrose concentrations (10%, 15%, 20%), sowing times (fresh pollen, 7 days old pollen, and 14 days old pollen), temperatures (10 degrees C, 15 degrees C, 20 degrees C, 25 degrees C) and ...

In vitro germination of apple pollens

Scientia Horticulturae, 1979
Abstract In order to characterize pollen viability and germinability by biochemical parameters, an introductory investigation was made of the germinability in vitro of pollen of 2 apple cultivars, ‘Golden Delicious’ and ‘Starkrimson’, partially self-incompatible and totally self-incompatible, respectively.

In vitro germination of black walnut pollen

Canadian Journal of Botany, 1971
Black walnut pollen was germinated on liquid and agar-based media containing 20% sucrose, a requirement for germination and normal tube development. Boron (100 ppm boric acid) added to this medium slightly enhanced germination. Germination occurred only in dense (150+ grains/mm2) populations of pollen on the agar medium. This population effect was not

In Vitro Analysis of Cotton Pollen Germination

Agronomy Journal, 2004
Crops with economically valuable reproductive structures show the greatest negative discrepancy between average and record yields. To alleviate environmental stress–related yield reductions, a better understanding of the relative sensitivities of pollen development, dehiscence, pollen germination, pollen tube growth, fertilization, and subsequent boll ...
