Abstract: | Summary After double or triple pollinations including selfing and the use of one-day-old compatible foreign pollen a severely self-incompatible clone could be forced to develop a reasonable amount of self-seeds per flower head. This number of self-seeds increased when the foreign pollination was delayed for e.g. 240 minutes in the double pollination experiment. Even more self seeds were obtained in the triple pollination experiment with a delayed second selfing.The influence of the old foreign pollen may be caused by a mentor pollen or a pioneer pollen effect. |
