Culture of Pinus Radiata Embryos with Reference to Artificial Seed Production
Embryos excised from mature Pinus radiata D. Don seeds were cultured in a small volume of a nutrient medium contained in a small aluminium capsule to form an artificial seed. The embryos developed with normal morphology, although not as large as those from natural seeds. All plants from artificial seeds formed roots in sterile soil. The growth of embryos placed radicle-down into the same agarif...
متن کاملAnaerobic Xylanolytic Bacterium from Decayed Pinus patula Wood Chips
An anaerobic, mesophilic, sporeforming, xylanolytic bacterium was isolated from decayed Pinus patula wood chips. The cells of this organism were gram-negative rods, had peritrichous flagella, and formed terminal round endospores which distended the cell wall. Xylan, cellobiose, fructose, glucose, maltose, mannose, melezitose, raffinose, rhamnose, salicin, sucrose, and xylose were utilized. The ...
متن کاملInitiation of somatic embryogenesis from immature zygotic embryos of oocarpa pine (Pinus oocarpa Schiede ex Schlectendal).
The focus of the current project was to establish somatic embryogenesis protocols for the tropical pine species Pinus oocarpa using immature zygotic embryos (ZEs) as explants. Somatic embryogenesis is best supported by mimicking natural seed-embryo developmental conditions, through a tissue culture medium formulation based on the mineral content of the seed nutritive tissue [megagametophyte (MG...
متن کاملInduced resistance and associated defence gene responses in Pinus patula
Background Plants are able to incite a type of broad spectrum resistance against pathogens upon pre-treatment with biological or chemical inducers. Systemic Acquired Resistance (SAR) and Induced Systemic Resistance (ISR) are two types of induced resistance which lead to the accumulation of specific pathogenesis-related (PR) proteins. Non-pathogenic rhizobacteria are inducing agents for ISR and ...
متن کاملPhytochrome in Embryos of Pinus palustris.
Phytochrome has been shown to be involved in the germination of seeds of a number of pine species as determined by the responses of these seeds to red and far-red irradiations (4, 7, 9). Nyman (7) found that even before imbibition, germination of Pinits silvestris seeds can be promoted by red irradiation. McLemore (5) found that germination of longleaf pine seed (P. palustris) can be repeatedly...
