Abstract
The effects of temperature,boron,calcium,pesticide and germicide on pollen germination and tube growth of strawberry were studied in culturing pollens in liquid media.The results showed that the most suitable temperatures for pollen germination and tube growth were 25 to 30 ℃.The external boron was needed in pollen germination of strawberry at 0.33 g/L being the most suitable concentration.The pollen germination of strawberry was not obviously related to external Ca2+,but accelerated by the application of Ca2+,the effect of Ca2+ was most significant at the concentration of 0.33 g/L,while pollen germination was inhibited by Ca2+ when the concentration was higher than 0.3 g/L.The germination of strawberry pollen was susceptible to the common pesticide and germicides.
