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 کاملPast and future of a century old Citrus tristeza virus collection: a California citrus germplasm tale
Citrus tristeza virus (CTV) isolates collected from citrus germplasm, dooryard and field trees in California from 1914 have been maintained in planta under quarantine in the Citrus Clonal Protection Program (CCPP), Riverside, California. This collection, therefore, represents populations of CTV isolates obtained over time and space in California. To determine CTV genetic diversity in this conte...
متن کاملUnivariate and multivariate statistical tools for in vitro conservation of citrus genotypes
This study aimed to evaluate the influence of the growing environment on the in vitro conservation of citrus genotypes obtained from the Active Citrus Germplasm Bank of Embrapa Cassava and Fruit. The study used multivariate statistic tools in order to improve the efficiency in the analysis of the results. Approximately 1-cm of length microcuttings from plantlets derived from ten genotypes previ...
