Happy Cadaver Posted April 17, 2002 i think its supposed to contains LSA's produced by a symbiotic fungi on the seeds. but i may be wrong. Share this post Link to post Share on other sites
Guest reville Posted April 17, 2002 Mine have plenty of seed on them now but im not sure if its activei need to stain the 'pith' of the flower stalk to spot the fungus If its there ill be selling plants in spring. Share this post Link to post Share on other sites
spikey Posted April 18, 2002 i think u got something wrong here... the symbiotic fungi that makes LSA is called ergot, now that is found on wheat in china stipa robtusa or how ever is spelled is from the americas i think it's produces lsa in the leaves naturaly.. but i ain't no ethnobotany proffesor Share this post Link to post Share on other sites
Torsten Posted April 18, 2002 Originally posted by spikey: i think u got something wrong here... nope. the symbiotic fungi that makes LSA is called ergot it's not the only one. It is parasitic and not symbiotic. now that is found on wheat in china and europe and america and australia and everywhere else just about. stipa robtusa or how ever is spelled robusta, ie from robust = tough. i think it's produces lsa in the leaves naturaly no, it hosts a fungus (I think acremonium), which produces the LSA.

Guest reville Posted April 19, 2002 The fungus in Stipa robusta is an 'Acremonium' this is an old term that has been out dtaed by several new genus names The fungus lives within the plant tissues and benefits the plant by inhibiting insect , herbivore and pathogen pressures When the plant flowers the fingus grows up thrugh the flower spike to infect the seed. It nestles into the husk of the seed and is carried this way. the fungus infects the new seedling within a week or so of germination and should be detectable by the time it forms its first mature leaf blades The interesting thisng about stipa robusta and its partner is that it produces 10 time the LSA's as Tall fescue and its symbiont. There is much more info about this species on the web so i suggest a serach. Just how relevant it is to Stipa is the topic of my own personal investigations.
