Part of the work described in the following progress report was conducted by Enrique Stein, Graduate Student in Subtropical Horticulture, University of California, Los Angeles, under the direction of Professor George F. Ryan.
author notes
The above progress report is based on Research Project No. 1068.
James F. L. Childs, Pathologist, and Gustave Hrnciar, Fruit and Vegetable Crops and Diseases, United States Department of Agriculture, conducted the studies in Florida mentioned in this report.
H. B. Frost, Associate Plant Breeder, Emeritus, University of California, Riverside, advanced the possibility that toxic action of fungi or bacteria might affect the presence or absence of chlorophyll in citrus seedlings.
J. M. Tager, Plant Physiologist, University of Pretoria, Pretoria, South Africa, and S. H. Cameron, Professor of Subtropical Horticulture, University of California, Los Angeles, determined that removal of the seed coat prevents albinism.
