The Use Of Foliar Applied Zinc Compounds In Correcting Zinc Deficiency In Fruit Crops, Lynn F. Hall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effectiveness of two chelated zinc compounds in correcting zinc deficiencies was studied. Soil and foliar treatments were made to study possible residual zinc carry-over from one season to the next. Foliar treatments at various rates were applied to raise plant tissue zinc levels above deficiency levels. It was found that none of the treatments studied resulted in any substantial carry-over of zinc to the following year. All of the foliar zinc treatments resulted in an increase in leaf zinc content in all of the varieties of fruit studied. The level of zinc in the treated trees increased in proportion …

Anthocyanins Of Fresh And Stored Freeze-Dried Sour Cherries In Compressed Form, Suwan Potewiratananond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Anthocyanin pigments of sour cherry (prunus cerasus L., cultivar Montmorency) fruit were studied by spectrophotometry, paper and two-dimensional thin layer chromatography and disc electrophoretic method. Mature and wholesome fresh sour cherries and freeze-dried compressed sour cherries stored at 70 F and 100 F for 6 months were used.

A total of seven anthocyanin pigments were observed in both paper and thin layer chromatograms of the fresh and freeze-dried compressed samples stored for O month whereas the freeze-dried compressed samples stored at 70 F and 100 F for 6 months showed the retention of three to six pigments. All of …
