Interspecific pollen competition among Populus deltoides, P. nigra and P. maximowiczii in fertilizing P. deltoides ovules was studied by using a pollen mixture technique, allozymes and leaf morphology. The frequencies of F1 seedlings of different paternities in pollen-mix crosses showed highly significant (P<0.01) departures from the 1∶1 ratio expected if pollen selection was random. P. deltoides pollen was the most competitive. The mean percentages of F1 seedlings of P. deltoides paternity in… CONTINUE READING
