A multivariate technique was employed to assess tree-ring growth and climatic relationships of white oak in northern Illinois-Indiana, including LaPorte, Ind. Climate accounted for 59% of the variance in ring-width chronology, and prior growth accoun

1. Basswood seedlings were grown in sand and in solution culture in a chamber with a sealed atmosphere. Growth of plants receiving minus-sulfur nutrient solution was markedly limited. Those receiving complete nutrient grew vigorously. 2. Visual sympt

1. Growth and flowering responses to temperature and photoperiod were studied for six grasses that grow in the San Gabriel Mountains of southern California. The grasses included a native annual or shortlived perennial, California brome (Bromus carina

Only small variations in relative turgidity were found for native, disjunct shortleaf pine (Pinus echinata) before and at the end of a record 48-day drought. Remnant 25-year-old plantation shortleaf pine underplanted with hardwoods had relative turgi

The feasibility of using lithium-7-fluoride thermoluminescent dosimeters under field conditions for natural radiation at levels of 5 milliroentgens is demonstrated. Radiation dosages in tree trunks increased threefold from winter to spring and summer

Plotless vegetation sampling including the quarter method results in a systematic bias if measurements "to the tree" are used in place of the center of the tree trunk. Widely used references show "to the tree" measurements which lead to overestimates
