Effect of flower size-dependent anther-stigma separation on mating pattern of Tulipa iliensis.

Flower sized dependent anther-stigma separation distance (ASS) may influence self and out-crossing rate in animal-pollinated species. The correlation between flower size dependent anther-stigma separations and mating patterns has been poorly studied so far. We predicted that flower size significantly affects ASS and cross pollination in the insect-pollinated, incomplete herkogamic Tulipa iliensis. We studied floral size dependent variation in ASS, nectar production, pollinator behavior, visiting frequency, pollen deposition and seed production of self, natural and cross pollinated flowers of T. iliensis. The study revealed that ASS decreased with increasing flower size while nectar volume andr visiting frequency increased with increasing flower size. Pollen deposition and seed set in natural and outcrossed flowers increased with increasing flower size. While pollen deposition and seed set of autonomous self-pollinated flowers decreased with increasing flower size. This result suggests that flower size and ASS play crucial role for the reproductive success in T. iliensis.
