“…Because mature kernel weight is well correlated with endosperm cell number, the extent of cell division may place an upper limit on the amount of storage material synthesized at subsequent stages of endosperm development (Setter and Flannigan, 1989). Salvador (1988) developed a simulation model called CENTLI to simulate maize kernel development and final kernel weight in a sink-pulled fashion, while accounting for the fact that basal kernels have more strength to attract assimilate than the tip-kernels.…”

“…Silk growth was calculated by using pubh'shed data (Sadras et al, 1985;Ritchie et al, 1993). Grain filling period is simulated by using a method presented in CENTLI (Salvador, 1988). Both water and temperature stresses were simulated using the method of CERES-Maize (Jones and Kiniry, 1986).…”

“…Under field conditions, the reproductive stage begins when silks are visible outside the husk (Ritchie et al, 1993). Maize-S accounts for the effect of leaf senescence on leaf area index after silking using the method of Salvador (1988). Fertilization of the silks is simulated by calculating daily percentage of silk emerged, silk length, and pollen tube length.…”

“…A pollen grain captured by moist silks grows down the silks to the ovule, where fertilization occurs and the ovule becomes a kernel (Ritchie et al, 1993). To determine the time when fertilization occurs, pollen growth rate (mm/day) is calculated and summed to calculate pollen tube length according to the method of (Salvador, 1988). (Table 3) and multiplied by 4, which represent the number of ovules per one centimeter of ear at silking (Ritchie et al, 1993) as follows:…”

Soil, and Water Research Laboratory at Temple, Texas. CERES-Maize requires two input files: the parameters input file and the weather-input file. The parameters input file contains variables for sowing date, plant population, latitude, planting depth, model output switches, irrigation switch, initial soil water status, soil water balance switch, soil parameters, irrigation dates and amounts, and genetic inputs. The genetic inputs are of three types: the relationship of growing degree days to phenological events, a photoperiod sensitivity coefficient, and yield estimates in terms of potential kernel number and potential kernel growth rate. The weatherinput file contains the variables: year, day of the year, daily values of total incoming solar radiation, maximum and minimum air temperature, and precipitation (Jones and ECiniry, 1986). Maize Vegetative Development The state of a plant is determined by both growth and development. Growth is the increase in weight, length, or area of the plant. Development is the sequencing of phenological events in the plant life cycle (Ritchie and NeSmith, 1991). The maize plant
