- Abstract:
- The phenomenon termed "photoperiodism" refers to the development of plants in relation to the length of the daily light period. It was found that certain herbaceous plants would not flower if they were planted northward or southward of their respective range limits. In order to obtain more information on the effect of day length on trees it seems advisable to use fast growing species with a wide latitudinal range. The experiment was conducted with clones of two species of Populus - Populus trichocarpa and Populus deltoides....
- The work was done under sponsorship of the Maria Moors Cabot Foundation for Botanical Research at the green houses of the Arnold Arboretum, both of Harvard University, in the immediate vicinity of Boston.
