The objective of the work was to understand the influence of the leaf-rolling trait on grain yield and quality, and develop wheat germplasm containing the leaf-rolling trait... The role of bulliform cells is still controversial in the literature and we are currently assessing cell anatomy for a set of twelve lines and cultivars that show different responses for leaf rolling... The commercial parents used for this work were Janz and H45...

FINAL REPORT DAW00032: Improving weed management with biserrula in the pasture phase of WA cropping systems - Dr Clinton Revell, DAFWA Result Summary (i) Pasture /crop rotation trial - Cunderdin (central wheatbelt).. Santorini Rotations: PCPCP, PCCCP Tillage in crop years: cultivate/seed (CS), direct drill (DD) Main plot size: 35m x 12m, three replicates.. 1.after plots cultivated for CS treatment..

Black point discolouration appears to be similar to enzymatic browning characteristic of plant tissues subjected to physical damage, which involves the oxidation of phenolic compounds present in plant tissues by polyphenol oxidase (PPO) or peroxidase (POX) and the transformation of the oxidation products to dark pigments... In order to determine differences in enzymatic activity of clean and black-pointed grains, and the suitability of black-pointed barley grain for use in malting and brewing, POX and PPO were measured during grain development using enzymatic activity assays and isoelectri...

The extremely low incidence of seed damage assessed in all SA trials is likely to be attributed to the lack of E. behrii pressure during 2005... The aim of the study was to assess the efficacy of several candidate insecticides for the control of E. behrii in lentils... Results obtained from the Vic trial suggest that deltamethrin and esfenvalerate can effectively control damage caused by E. behrii to lentils when applications are timed appropriately...

Where dryland salinity threatens the productivity of agricultural land there is a need for farmers to formulate considered responses... From the areas identified by farmers we noticed that mid and upper slope farmers have just as much area of concern (often brackish hillside seeps) and recent outbreaks on their farms as valley floor farmers... There is a need for farmers and catchment groups to invest greater effort in risk assessment and to link the need to know to the risk at given sites...

Mortality and reproduction of adult beetles exposed for two weeks to wheat treated with combinations of spinosad, s-methoprene# and chlorpyrifos-methyl#. The species tested were Sitophilus oryzae strain QSO393 (So), Tribolium castaneum strain QTC279 (Tc).. Mortality and reproduction of adult psocids exposed for two weeks to wheat treated with combinations of spinosad and chlorpyrifos-methyl...

Identical to Herald strand medic but with the addition of excellent tolerance to SU herbicides applied 4 to 12 months before sowing... Effect of SU herbicide applied in January and February at 0, 50 & 100% of suggested summer rates, (metsulfuron methyl - 3.5 & 7g/ha of product triasulfuron - 9 & 18 g/ha) on the dry matter production of Angel and Herald sown four months later at a low rainfall alkaline soil site on Eyre Peninsula... The options for controlling weeds in the pasture phase for Angel are essentially the same as for other medics...
