✦ Synopsis
Causes of flower formation are factors of great current interest in phases of plant growth studies. Vernalization, which is concerned with a temperature gradation such as the effects of cold upon seed germination, and photoperiodism, as it deals with the effects of varying day lengths, are two fields of study from which one seeks possible explanations of why plants flower. Murneek and Whyte's Symposium makes use of collaborations from other ex- perts and gives an outstanding review of the major concepts from the fields of vernalization and photoperiodism. The text does not give the final explanation of flower formation, but rather brings together leading researches which stimulate the student to his fullest conjecture.
There are eleven discussions and three special supplements, plus numerous tables and plates. Included is a n interesting scientific discussion of the "controversial" aspect of Lysenko's findings. Generally the Symposium is directed to concepts of economic significance in agriculture. However, frequent use of certain important drug plant material renders it of considerable value to the pharmacognosist as well.-H.
