Abstract

Quantitative investigations of climatic factors in the immediate habitat of both native and cultivated plants in the field and of the effect of these factors on the growth of the plants have proved that climatic factors may vary sufficiently within relatively narrow limits in space to produce significant variations in the development of plants. These contributions have had an important influence on the growth of the concept of microclimate and on the recent interest and research in this field. At present there is urgent need of information on the determination of the size of microclimatic areas and of the critical factors to be measured (2, 3, 6, 7, 10). These two questions must be considered on the basis of the magnitude of microclimatic differences and of the nature and degree of reaction of the plants to them. The microclimatic area considered needs be no smaller and the number of factors measured no greater than is necessary to determine definite relationships between differences in climatic factors and variations in plant response.
