The micro-Kjeldahl method for nitrogen determination has been widely used in organic chemistry laboratories in recent years. The value of this method, developed through the brilliant researches of PiLcH, BANG, PARNAS and WAGNER, PREGL, and coworkers, has justified its application to industrial and clinical problems. Plant physiologists have not generally adopted quantitative micro-methods for n...

ETHNOPHARMACOLOGICAL RELEVANCE N-Alkylamides (NAAs) are a promising group of bioactive compounds, which are anticipated to act as important lead compounds for plant protection and biocidal products, functional food, cosmeceuticals and drugs in the next decennia. These molecules, currently found in more than 25 plant families and with a wide structural diversity, exert a variety of biological-ph...

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...

A brief overview of biological activity of organotin compounds is given, with emphasis on activity against plant-feeding arthropods. Plictran miticide, containing cyhexatin (tricyclohexylhydroxystannane), the first product to be fully commercialized for control of plant-feeding mites on a broad range of agricultural crops, is used as a model to indicate the chemistry and potential performance, ...

Fungal symbionts that live asymptomatically inside plant tissues (endophytes) can influence plant-insect interactions. Recent work has shown that damage by leaf-cutting ants, a major Neotropical defoliator, is reduced to almost half in plants with high densities of endophytes. We investigated changes in the phenotype of leaves that could influence ants' behavior to result in the reduction of fo...

Measurements which show the potential for corrosion of a plant’s metallurgy due to interaction with the system water have gained in importance within the last two decades. Among the most successful of these measurements are those which measure an actual potential which is based upon the oxidation/reduction reactions taking place. The measurement of Oxidation Reduction Potential (ORP) has been u...

Tannins, an abundant group of plant secondary compounds, raise interest in different fields of science, owing to their unique chemical characteristics. In chemical ecology, tannins play a crucial role in plant defense against pathogens, herbivores, and changing environmental conditions. In the food industry and in medicine, tannins are important because of their proven positive effect on human ...
