This computer application, called Siro Fire, is a DOS protected mode application that incorporates several fire spread models that can be applied to the two major fuel types found in Australia-grass and forest. It uses GIS-derived geographic maps and digital elevation models to calculate the probable spread of a fire across the landscape and displays the results on a graphical representation of the map of the area of concern. The application is being used in the South Australian Country Fire Service as both an operational and training tool. This paper outlines the evolution of previous fire spread simulation software, the development of SiroFire and how SiroFire carries out fire spread simulations using existing fire spread prediction algorithms.

The basic experimental data were obtained from a series of glasshouse experiments under six temperature regimes in natural light. The data for leaf development rates showed a change in the response to temperature at the first trifoliate leaf stage; this was incorporated into the model. The flower initiation model included parameters for the production and decay of a theoretical flower promoter and for the rate of change of daylength. Time to flower initiation showed a complex relationship to photoperiod which could not be described or approximated to by any simple function. The effects of temperature were marked and showed a strong interaction with photoperiod. The flower development model accounted for a strong temperature response which was conditioned by a photoperiod effect. The three models were combined to form a soybean phenology model which was validated against phenological data obtained from date of sowing experiments conducted under field conditions.SpringerLink - Journal Articlehttp://www.bibsonomy.org/bibtex/2d2be43cc461b25ee81293d856ed2d008/jgomezdansjgomezdans2008-05-15T14:22:58+02:00phenology evapotranspiration yield crops agriculture <span style="color:#555555;">B.

The purpose of the study reported here was to establish relationships between crop temperature and the grain yields, phenological development, evapotranspiration rates (ET) and leaf water potential (?l) of two hybrids of grain sorghum (Sorghum bicolor L. Moench) subjected to varying levels of plant water stress. The study was conducted at the University of Nebraska Sandhills Agricultural Laboratory in 1978 on a Typic Ustipsamment (Valentine fine sand) soil. The sorghum hybrids used were RS 626 and NB 505. Four irrigation treatments were applied in order to subject the crops to varying levels of water stress during each of three major growth stages. Soil moisture was monitored with a neutron probe. ET was estimated with the water balance technique. Crop temperature was measured with an IR thermometer and leaf water potential was measured with a Scholander pressure bomb. Grain yields were reduced by water stress occuring at anytime during the growing season. Yield reductions were largest when stress occurred during only the grainfill period and were least when stress occurred during the entire growing season. The percentage reduction in sorghum grain yield can be described by an index involving the seasonal accumulation of the daily mid-day temperature differences between well-watered and stressed crops (S TSD). As S TSD values increased, ET decreased. However, the correlation of ET with S TSD was relatively low (R2 = 0.60) probably due to the limited amount of data available for analysis and inaccuracies in the soil water balance method used to estimate ET. The mid-day temperature of well-watered rows ranged between 18.0 and 32.8 °C with a mid-day temperature range of about 0.5 °C between the well-watered rows in various plots for several days following an irrigation. However, in certain instances, the mid-day temperature range increased to 1–2 °C for a few days before irrigation. This suggests that certain of the rows experienced water stress and should have been irrigated earlier. Yield data support that conclusion. Range in crop temperature within a field appeared to be a sensitive indicator of crop water stress in sorghum. No significant difference in the phenological development of sorghum resulted from water stress except in one NB 505 plot in which plants were stressed throughout the entire season. In that plot, the stressed plants lagged in development behind non-stressed plants by approximately ten days. The differences in mid-day leaf water potentials (??l) and crop temperatures (?T) between stressed and non-stressed vegetation were examined. As ?T increased up to about 4 °C, ??l, also increased. Beyond that point, ??l decreased while ?T continued to increase. This behavior was attributed to stomatal closure which permitted an increase in ?l of the stressed plants (hence reducing ??l) even as ?T continued to increase.
