Chemistry of Plant Growth Substances

The Chemistry and Mode of Action of Plant Growth Substances

In the last section of the book genetic, hormonal, and enzymatic factors affecting the growth of the nervous system are taken under consideration. Excellent reviews of genetic aspects are given by S. Gluecksohn-Waelsch and L. S. Penrose. G. W. Harris contributes a thoughtful chapter on the relationship between endocrine activity and the development of the nervous system. Although most of the ma...

Roles of Plant Growth Regulating Substances

Evaluation of the effect of plant growth substances on longevity of gerbera cut flowers cv. Sorbet.

Gerbera is one of the most popular cut flowers in the world. Several experiments have been done on the effect of different chemical compounds on longevity and quality of cut flowers. In the present study, two experiments based on a completely random design with two treatments and three replications were conducted on gerbera cut flower cv. Sorbet. The first experiment examined the effect of BA, ...

Practical Applications of Plant Growth-substances in Horticulture

Separation of Plant Growth Regulating Substances on Silica Gel Columns.

The preparation of the silica gel is similar to the method of Bulen, et al (2) for organic acid chromatography. Silicic acid (Mallinckrodt's 100 mesh analytical reagent) is prepared, generally in one pound batches. by repeatedly washing it in distille(d water, and decanting the fine particles that do not settle out of suspension after an arbitrarily chosen period of 15 minutes. After the silici...
