Physiological and biochemical studies of stratified Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seeds after redrying, storage, and subsequent germination

Creator:

Malavasi, Marlene de Matos

Abstract:

The physiological and biochemical responses of Douglas-fir seeds to stratification, redrying, storage and subsequent germination were determined. Stratification increased seed vigor, embryo and gametophyte phosphorylative efficiency and RNA synthetic ability. Redrying seems to increase the rate of enthryonic nucleic acid synthesis, speed of germination and seedling vigor. ATP, total adenosine...

Standardization of the tyrosinase test for identification of wheat varieties

Creator:

Matos, Marlene de

Abstract:

This study was undertaken to standardize and evaluate the tyrosinase test as a variety identification procedure for wheat. The potential value of the tyrosinase test lies in its ability to quantify the colored products, rather than relying on visual estimation as in the phenol test. The specific objectives of this...
