Environmental and genetic control of morphogenesis in crops: towards models simulating phenotypic plasticityCSIRO Publishing - Tập 56 Số 11 - Trang 1289 - 2005
Michaël Dingkuhn, Delphine Luquet, Bénédicte Quilot‐Turion, Philippe de Reffye
As molecular biologists are realising the importance of physiology in understanding functional genomics of quantitative traits, and as physiologists are realising the formidable prospects for improving their phenotypic models with information on the underlying gene networks, researchers worldwide are working on linked physiological–genetic models. These efforts are in their early methodo...... hiện toàn bộ
Photosynthetic dysfunction and in vivo changes in chlorophyll a fluorescence from manganese-deficient wheat leavesCSIRO Publishing - Tập 36 Số 2 - Trang 157 - 1985
PE Kriedemann, RD Graham, JT Wiskich
Leaves on wheat plants growing in manganese-deficient media showed much higher constant-yield fluorescence (Fo) but greatly reduced variable fluorescence (Fv). Higher Fo was symptomatic of a stronger overall emission which derived from functional changes within photosynthetic membranes and was not simply attributable to differences in leaf reflectivity of wavelengths relevant to fluorescen...... hiện toàn bộ
The analysis of adaptation in a plant-breeding programmeCSIRO Publishing - Tập 14 Số 6 - Trang 742 - 1963
K. W. Finlay, GN Wilkinson
The adaptation of barley varieties was studied by the use of grain yields of a randomly chosen group of 277 varieties from a world collection, grown in replicated trials for several seasons at three sites in South Australia. For each variety a linear regression of yield on the mean yield of all varieties for each site and season was computed to measure variety adaptation. In these calculat...... hiện toàn bộ
Phosphorus export at the paddock, farm-section, and whole farm scale on an irrigated dairy farm in south-eastern AustraliaCSIRO Publishing - Tập 56 Số 1 - Trang 1 - 2005
Kirsten Barlow, David Nash, Rodger B. Grayson
Phosphorus (P) exported from agricultural land contributes to the eutrophication of inland water systems. Although P export has been extensively researched at the paddock scale, our understanding of farm-scale export is limited. This paper presents the results of a 3-year monitoring project that investigated P export at the paddock, farm-section, and whole farm scales on an irrigated dair...... hiện toàn bộ
The histotropic phase of the nematode parasite, Ostertagia circumcinta.CSIRO Publishing - Tập 5 Số 1 - Trang 130 - 1954
R. I. Sommerville
The histotropic phase of Ostertagia circumcincta in the abomasal mucosa of the sheep has been investigated. Larvae were found to enter the gastric pits and glands and there pass the third ecdysis, three days after oral administration to the host. Some of these larvae failed to grow after ecdysis, and were found in the mucosa as long as three months from the date of infestation. Other lar...... hiện toàn bộ
Thermal status of sheep at pasture in western New South WalesCSIRO Publishing - Tập 22 Số 5 - Trang 797 - 1971
GD Brown
The thermal status of three unrestrained rams at pasture was studied for a period of 5 days during March in central western New South Wales. A temperature telemetry system was used to measure rectal temperatures, skin surface and subcutaneous temperatures on the mid back, and subcutaneous temperatures of the scrotum of each ram. Rectal temperatures of 40�C and above were recorded for all r...... hiện toàn bộ
Radiation use efficiency increases when the diffuse component of incident radiation is enhanced under shadeCSIRO Publishing - Tập 49 Số 4 - Trang 665 - 1998
K. D. Healey, Graeme Hammer, K. G. Rickert, M. P. Bange
Theoretical analyses have shown the radiation use efficiency of maize,
soybean, and peanut to increase with a decrease in the level of incident
radiation and an increase in the proportion of diffuse radiation. This study
compared the growth and radiation use efficiency of
Panicum maximum cv. Petrie (green panic) and
Bothriochloa insculpta cv. Bisset (creeping bluegrass)
beneath shading tr...... hiện toàn bộ
