Micronutrientsnificance(33). The growing tendency to allocate reject lands to forestry(109) justifies substantial research effort on the physiological, biochemical and genetic effects of these elements on forest tree species. It is one aim of this chapter to provide some guidance on the use of tissue culture systems for studies of defined micro-nutrient stress.

Measured

Metabolic and Non-Metabolic Roles of Carbohydratesquently the development of photoautotrophism may be incompatible with many applications of plant tissue culture technology, themselves requiring specific hormone levels and balances, and thus we may regard the exogenous carbohydrate supply as essential for successful culture.

Measurement and Origin of Genetic Variation in Tissue Culture Systemsncreased interest in these species due to economic and academic considerations and improved technologies for genetic analysis at the cellular and molecular levels, this situation will probably change soon.

Nitrogen Nutritionegulating substances, including auxins and cytokinins, contain nitrogen. In addition to forming the backbone for polypeptides, amino acids perform numerous functions. Proline has been implicated as an osmoregulatory substance (14) and polyamines have been implicated in regulation of development (89).

Commentary

Clonal Propagation of Mature Trees: Problems and Possible Solutionsies later in their life cycle. Some species show reasonable juvenile-mature correlations for a few characteristics (79) and for these, selections can, under certain circumstances, be made at an early age. However, for many species, most foresters prefer to select sexually mature trees of about half the rotation age (82).

参考书目

DNA in Tree Speciesies are typical eukaryote genomes that differ from prokaryotes by their larger size, increased information content, excess of non-coding (repetitious) DNA, association of the DNA with acidic and basic proteins, and separation from the cytoplasm by a nuclear envelope.
