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 ...

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 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.

Pollen Germination and Pollen Tube Growth in Vitro

1992
Pollen germination and pollen tube growth are prerequisites for fertilization and seed development. Because of the involvement of the pistillate tissue in nature, physiologic and biochemical investigations on pollen germination and pollen tube growth in vivo are rather difficult. In vitro germination techniques have therefore been used extensively on a

A NEW MEDIUM FOR POLLEN GERMINATION IN VITRO

Acta Botanica Neerlandica, 1982
SUMMARY Poly-ethylene glycol (PEG)-400 was found to be superior to sucrose as the major component in media for the germination of Petunia hybrida pollen. PEG promotes pollen tube growth considerably more than sucrose. Pollen tubes grown on PEG resemble the in vivo tubes much more than those grown on sucrose.
