Abstract. The exudate production of alfalfa under the conditions of the sterile flow culture was quantitatively measured. In the first 40 days 3.10-3 ,mmoles amino-N, 2.5 ,,uequivailents of organic acids and approximately l04 ,moles of reducing sugars were liberated per plant and per day into the percolating nutrient solution. The amino acid concentration in the outflow varies according to a daily periodicity. The exudation of a colored substance also shows daily periodical variations. This pattern is d6ifferent from the pattern of the amino acid exudation, however, and directly coupled to -shoot illumination. Short-term 2,4-dinitrophen,ol additions to the nutrient lower the liberation of amino acids into the percolating soilution.Much work has been done to learn more about the special conditions and processes which characterize the plant root rhizosphere. Some literature reviews concerning root exudates were published since 1964, considering the more general character (32,33) as well a's the special aspects of the subject (2, 7). Several papers presenting quantitative and semi-(Iuantitative data on exudate production were the background for the experiments and results here to be described.

“…Across all treatments, sucrose at 20 g L -1 was best for shoot proliferation. Sucrose may be generally superior to glucose because it is more effectively translocated to apical meristems (Butcher and Street 1964). However, shoot growth in 'NL1' was supported equally well by glucose and sucrose, and at 10 g L -1 glucose resulted in better in vitro growth.…”

Debnath, S. C. 2007. Strategies to propagate Vaccinium nuclear stocks for the Canadian berry industry. Can. J. Plant Sci. 87: 911-922. Vacinium fruits are genetically heterozygous species characterized as "not coming true from seed". Conventional methods for vegetative propagation of these species, although successful, are slow and labour-intensive, and few propagules can be produced from one plant of a selected clone or hybrid. Micropropagation techniques are important for clonal multiplication, germplasm improvement and gene conservation of Vaccinium fruits cultivated in Canada including blueberries, cranberries and lingonberries. In vitro propagation of these species using axillary bud proliferation and adventitious shoot regeneration has been investigated in a number of studies. Morphogenesis seems to be highly dependent on plant growth regulators and media used for culture, and this dependence is genotype specific. The paper presents the progress in-depth of various aspects of the in vitro culture of Canadian Vaccinium species for their commercial production. Also discussed are techniques for clone rejuvenation and plant tissue culture for mass propagation of Canadian Vaccinium nuclear stocks. Les techniques de multiplication végétative in vitro revê-tent une grande importance pour la multiplication des clones, l'amélioration du matériel génétique et la conservation des gènes des fruits du genre Vaccinium cultivés au Canada, notamment le bleuet, la canneberge et l'airelle vigne-d'Ida. Diverses études se sont penchées sur la multiplication in vitro de ces espèces par prolifération des bourgeons et régénération des pousses adventives. La morphogénèse semble considérablement dépendre des régulateurs de croissance de la plante et du milieu de culture, une dépen-dance propre au génotype. L'article fait le point des progrès réalisés au niveau des divers aspects de la culture in vitro des espèces canadiennes du genre Vaccinium en vue de leur culture commerciale. On y présente aussi les techniques de rajeunissement des clones et de culture tissulaire pour la multiplication massive du matériel génétique des espèces canadiennes de Vaccinium.

“…Since the pioneering work on the establishment of root culture of tomato (White 1934a), roots of many plants are capable of independent growth to form secondary roots in culture (Butcher and Street 1964) and regenerate shoots. These shoots arise de novo from pericycle, as demonstrated in Convolvulus (Torrey 1958).…”

Gottlieb Haberlandt (Math Naturwiss 111:69-92), a German plant physiologist, for the first time initiated the work on tissue culture. His work arose as a research tool and attempts were made to culture the isolated, fully differentiated cells in nutrient medium in vitro as early as 1898. The theoretical basis of tissue culture lies in the cell theory given by Schleiden and Schwann (1838-1839). Practically, this technique stands on the concept of "totipotency," i.e., each cell has the ability to regenerate into a new plant. The field finds a wide range of applications starting from mass clonal propagation to plant improvement, molecular biology, bio-processing as well as a basic research tool. It has advanced the production in forestry and agriculture to many folds. There are a number of reviews published on tissue culture of woody and tree species which provide the wide-ranging micropropagation reports of various plant species. In this way, this chapter highlights the current review in tree tissue culture in vitro and micropropagation of other valuable plants, their significance, and the wide scope existing for investigations on mass multiplication and conservation of these plants.
