Alstroemeria, Aileen Reid

Bulletins 4000 -

About 60 species of Alstroemeria grow wild in South America, in habitats ranging from the snowline of the Andes and high mountain plateaus down through the highland forests to the coastal deserts.

A member of the lily family, Alstroemeria grows from a rhizome that also develops tuberous storage outgrowths and fleshy roots. The aerial shoots can be either vegetative or reproductive. Normally shoots that have unfolded more than 30 leaves will not flower and remain vegetative.

The leaves of Alstroemeria are unusual in that they rotate through 180 degrees as they unfold, so that the upper surface becomes the lower …

Current Status And 25 Year Trends For Soil Acidity, Fertility And Salinity In The Coastal Catchments Of The Peel-Harvey, Robert Summers, David Weaver

All other publications

The current status and trends of soil analyses in the coastal catchment of the Peel Harvey estuary were developed from historical soil data (1982 to 1991) combined with a renewed sampling to greater depth (1 m). This report encompasses the data collected from the first year of the project. Soil phosphorus content was found to be high but has dropped slightly since 1991. Soil pH is very low and is likely to be limiting production but have risen slightly since 1991. Soil potassium content is generally so low that it may be limiting production especially to the west of the …

Field Pea In The Great Southern, Ian Pritchard, Rodger Beermier, Mark Seymour

All other publications

Semi-leafless field pea like Kaspa have lifted the benchmark set by the previous conventional varieties such as Parafield and Dunwa. Semi-leafless field pea have the same traits as conventional field pea: adaptation to a range of soil types; wide selection of weed control options (including crop topping); nitrogen input; disease break; and reduction in root lesion nematodes. Semi-leafless pea is easier to harvest and is less prone to pod shatter.

Phytophthora Diseases Of Cutflower Crops, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Phytophthora root rot is the most common soil borne disease causing plant death in native cut flower production. It is also a pathogen of exotic cutflower crops such as rose, lily, carnation, proteas and gerbera. The fungus, Phytophthora cinnamomi, the cause of jarrah dieback is the pathogen that first comes to mind when Phytophthora is mentioned. This has one of the widest host ranges of all Phytophthora species, particularly amongst native Australia species. P.nicotianae also has a wide host range, infecting a wide range of exotic, as well as Australian native flower crops. There are also a number of …
