Methods of Conservation of the Plant Germplasm. in Vitro Techniques
In the last decade there has been an alarming increase in the number of disappearing species from the spontaneous flora due to the pressures put upon the environment (land clearing, drainage, pollution of the soil etc.) affecting their vitality, determining their number to fall under their biological possibilities of regeneration. In the present there are 60.000 vascular species on the verge of...

متن کاملCassava Germplasm Conservation and Improvement in India
Genetic diversity of cassava (Manihot esculenta Crantz), obtained by open or controlled pollination and selection, as well as from germplasm introductions from abroad, is being conserved, both in the field and in an in vitro gene bank. Nine hundred and eighty five germplasm accessions are being conserved under slow-growth conditions using an osmotic retardant medium. The major thrust given in t...
متن کاملTechniques in weak analysis for conservation results
We review and describe the main techniques for setting up systems of weak analysis, i.e. formal systems of second-order arithmetic related to subexponential classes of computational complexity. These involve techniques of proof theory (e.g., Herbrand’s theorem and the cut-elimination theorem) and model theoretic techniques like forcing. The techniques are illustrated for the particular case of ...
متن کاملNeutral genetic markers and conservation genetics: simulated germplasm collections.
This study examines the use of neutral genetic markers to guide sampling from a large germplasm collection with the objective of establishing from it a smaller, but genetically representative sample. We simulated evolutionary change and germplasm sampling in a subdivided population of a diploid hermaphrodite annual plant to create an initially large collection. Several strategies of sampling fr...
