Wall proteins of Vitis vinifera pollen. II. Influence of environment and rootstock on the electrophoretic pattern

Soluble wall proteins from Vitis vinifera pollen are genotypically determined and their expression, if not the extent of their expression, is independent from external factors. After the authors previously observed that the time of sample collection dose not influence their electrophoretic pattern, they demonstrate in the present work that this is true also for environment where the vine is growing and for the rootstock on which the scion is grafted.
