| Abstract:
Misshaped fruit is an important problem in strawberry production in the Huelva area (South-western coast Spain). Physiological and breeding studies on this topic require a deeper knowledge of factors affecting the fertilization process, such as pollen germination. To develop a simple and suitable medium to improve in vitro pollen germination of strawberry cultivars, liquid media containing different combinations of boron (from 0 to 350 ppm) and sucrose (5 to 25%) were tested. Percentages of pollen germination ranged from 0.5 to 56 %. The higher values were obtained on media containing 10-20 % sucrose and 100-350 ppm boric acid. | |
