A Contribution On The Staminate Flower Of Cucumis Sativus, Kenneth W. Simons

Electronic Theses and Dissertations

In Heimlich’s recent paper (2) on the staminate flower of Cucumis sativus, the conclusion was reached that the tetrasporangiate stamen was complete while the bisporangiate stamen was only half complete. In Miller’s more recent investigation of Schinocystis lobata (4), the bisporangiate stamen was shown to be complete and the tetrasporangiate stamen double. These opposing points of view suggest the advisability of further investigation in the Cucurbitaceae. Since Heimlich described two separate apical prolongations on each tetrasporangiate stamen and only one on the bisporangiate stamen, it seemed to the present writer that these prolongations might indicate the double and single natures …

The Effect Of Treatment With Ethylene Chlorhydrin Upon The Respiration Of Sweet Potatoes (Ipomea Batatas), Leon J. Tyler

Electronic Theses and Dissertations

1. Treatment with ethylene chlorhydrin produced marked results in the respiration of four of five varieties of sweet potatoes tried.
2. Not all varieties of sweet potatoes respond alike to the same treatment. Porto Rico variety of sweet potatoes did not respond to the treatment.
3. There was a considerable difference in the amount of CO₂ respired by different varieties.
4. The need for further research here with respect to the specific effect of chemicals upon the cell system becomes apparent and again emphasizes the importance of Biochemistry.
5. There was possibly an accelerative effect on sprouting due to increased respiratory processes brought about …
