AbstractThe control of pollen transfer is important for determining the components of yield performance of lupins. By tearing off the first, second and third petals and leaving the fourth and fifth untouched, key signals of the flower are removed and pollen vectors are prevented from visiting the flower. Although this partial removal of petals alters the biomechanics of the flower selfing remains unimpaired. The technique allows autogamy in to be obtained lupins under natural conditions and with little expense.
