Some Arctic Grasses

Grasses

over one’s genes? Perhaps it is because this notion resonates with a public that in the eighties and nineties the same press have bullied into believing that there is ‘a gene for everything’. In that sense, the debate is remarkably similar to the one on whether we humans (or animals in general) have such a thing as a free — or conscious — will. Much like with the idea of the vulgarised genetic ...

Fungal Endophytes of Grasses

Mutualistic interactions between species are receiving increased attention from ecologists, although research lags far behind analogous work on competition or predator-prey interactions. Most research has focused on rather showy mutualisms such as pollination or fruit dispersal and has suggested that mutualisms are more important in tropical communities than in temperate communities (67). Plant...

Nomenclatural Changes for Some Grasses in California and the Muhlenbergia Clade (Poaceae)

New combinations and names are here validated for ten grass (Poaceae) taxa in California for the forthcoming revision of The Jepson Manual. In addition, guided by recent molecular phylogenetic studies, ten non-California grass species are here transferred to Muhlenbergia (Chloridoideae: Cynodonteae) to achieve monophyly of the genus. Lolium, long known to be phylogenetically nested within Festu...

Bulletin No. 383 - Chemical Composition of Some Introduced and Native Grasses

A Survey of the Nonvolatile Organic Acids in Seedlings of Some Grasses and Legumes.

Root inhibition was also employed as an additional biological assay using cucumber seeds (variety i'vIarketer) as the test material. Seeds were germinated at room temperature (approximately 250 C) under laboratory conditions of alternatingf light and darkness on filter paper impregnated with a 0.005 -M solution of the compounds in Petri dishes. Four days after treatment the length of the primar...
