This study examined the effects of nutrient addition on pollen performance
(pollen germination, pollen tube growth, and siting success) in the wildflower Clarkia
unguiculata. Chamber-grown plants were watered with either a full strength commercial fertilizer
(20% nitrogen, 20% phosphorus, 20% potassium) or with distilled water. Pollen performance was
assessed in crosses between plants watered with nutrient solution and plants watered with
distilled water. The nutritional status of the pollen donor did not affect percent germination or
pollen tube growth. However, the nutritional status of the pollen recipient did significantly
affect pollen germination and pollen tube growth rates. Pollen from both donor types grew
significantly faster through the styles of plants watered with distilled water. Siring success,
as measured by seed production, did not differ significantly between any of the treatments. |
