Abstract/Contents: | "The abiity to predict phenology of crabgrass, such as time of seedling emergence and initial tiller development, could provide valuable insight for the development of the resources of efficient crabgrass management stragegies in turf. For example, several degree day models using mean temperatures have been developed to predict crabgrass seedling emergence. Each model may not be applicable to other regions and cropping systems since weeds are relatively heterogeneous plants and commonly have phenological plasticity under different environmental conditions. However, few studies have been accounted for the potential intra- and inter- specific variation of crabgrass species. The purpose of this report is to ascertain the differences that may exist in phenological and morphological characteristics within smooth and large crabgrass apecies. This information could improve the prediction models for more efficient crabgrass management in turf. Includes different methods, results and further discussion of the experiment. |
