title: Parthenocarpic Fruit Development from Grafted Ovaries of Cucuminis sativus L.
abstract: Reciprocal cleft and pistillate floral bud grafts were made between parthenocarpic ;Fertilla' and nonparthenocarpic ;MSU 713-5' cucumber (Cucumis sativus L.) lines to localize the site for stimulation of parthenocarpic fruit set. No fruit set on ;MSU 713-5' controls, scion grafted to ;Fertilla,' or rootstock with ;Fertilla' as the scion. ;Fertilla' controls, rootstock, and scions all produced parthenocarpic fruit when grafted to ;MSU 713-5.' When pistillate floral buds of ;MSU 713-5' were grafted to ;Fertilla,' no fruit were produced. However, individual immature pistillate buds of ;Fertilla' developed into mature fruits when grafted onto ;MSU 713-5.' Hence, the immature ovary is the site of stimulation for parthenocarpic fruit set in cucumber.
