  1. The physiological effects of heat stress on anthesis and pollination in domesticated sunflowers (Helianthus annuus L.)

    … rate, pollinator visits, pollen viability and stigma receptivity. We sampled during the anthesis period in a field setting under different summer conditions, including sunny and overcast days each with artificially heated and unheated plants; and a natural heatwave. Sunflower insect visits were …

    … and Dryandra formosa. The timing and pattern of stigma receptivity was determined using a combination of techniques. Findings can be used to breed and improve these species for further commercialisation in cut flower and garden industries. The study of pistil structure further identified the …

  3. The pollination biology of Haskap (Lonicera caerulea L.: Caprifoliaceae): floral traits and pollinator performance of a new Saskatchewan fruit crop.

    … anthesis length, nectar and pollen dynamics, and stigma receptivity in Haskap flowers. I observed that un-pollinated flowers bloomed for 3-4 days, but pollination triggered early senescence. Nectar was present at the onset of anthesis and did not increase significantly after 16 hours, and any …
