Morphological Development In Relation To Cold Hardiness Of Dormant Peach Fruit Buds, Schuyler Dranna Seeley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The morphological development of Elberta peach fruit buds was studied in relation to their cold hardiness.

Morphological development of peach fruit buds was observed beginning with bud differentiation in mid-summer. Flower initiation was essentially complete by September. Growth was slow in the winter months but increased rapidly as anthesis approached. Photomicrographs were taken to substantiate the discussion .

Cold hardiness determinations were made from December until anthesis in April. The hardiness level was greatest during December and remained at a relatively high level until rest ended. Hardiness decreased thereafter. Major losses of hardiness occurred just prior to anthesis.
