    Description

    Differences in survival, growth, and pest resistance of planted South Florida slash pine (Pinus elliottii Engelm. var. densa Little and Dorman) from two sources, two seed sizes, and three seedling grades are reported. Seedlings from northerly source had morphological characteristics more closely resembling typical slash pine than did those from the southerly source.  Six years after outplanting, the northerly source and large seedling grade grew fastest. Seedlings infected by the fungus Scirrhia acicola were smaller and had greater mortality than noninfected seedlings. These findings indicate the possibility of improvement in survival and early growth of planted South Florida slash pine by careful selection of see source and seedling grade.
