Forest Bulletin No. 88. Seasonal Progress of Height Growth in Trees

(a) A secondary maximum in the spring. (b) A secondary maximum after the break of the monsoon. (iii) Primary maximum after the break of the monsoon. [...] The relation of the maximum of the height growth curve to the date the monsoon sets in is strewn in the following table :— Year. [...] Though the work of PEARSON (9) and KORSTIAN (8) indicates that any such carried over effect is probably less important than precipitation during the period of rapid growth SCHUBERT (10) found close correlation between the height growth of a year for Scots pine and the aggregate piecipitation of August and the latter half of July of the previous year taken together with that of April and May of th [...] different ages were watched independently and exhibit very good agrement in the form of the curve and the dates of the growth peaks.; this was particularly the case in 1932 when the chief peaks were recorded on April 5 for both and on June 5 and 8. The details of the growth curves in the later months of the year vary considerably with a number of undulations which cannot be correlated with t [...] The specific curve for Dalbergia sissu which is based on the six years 1927-32 differs from all the rest in the exceptional flatness of the main growth peak indicating practically even growth from the end of March to the middle of June.
