Growth regulators on apricot: Seeds from apricot trees treated with growth regulators are inhibited in germination and any seedling growth is abnormal

Stratified Tilton apricot seeds, from trees sprayed in the spring of 1954 with 2,4,5-T — 2,4,5-trichlorophenoxyacetic acid—to increase fruit size and reduce preharvest drop, germinated very poorly after being planted in the nursery row in March, 1955. The few seedlings that did grow from these seeds were very abnormal when compared to seedlings from parent trees of die same variety mat had not been sprayed with 2,4,5-T.
