Book excerpt: Excerpt from Phenology and Other Features of the Flowering of Pines, With Special Reference to Pinus Monticola Dougl The authors soon realized the hopelessness of completely reviewing even that part of the phenological literature concerned only with forest trees. Early observers lacked uniform criteria for describing annual phenomena and varied in their skill in describing and recognizing floral stages. These factors as well as the bulk and inaccessibility of the older literature caused the writers to restrict their survey mainly to more recent publica tions on floral phenology of conifers.

This book was released on 2017-11-19 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Time of Flowering and Seed Ripening in Southern Pines Interest of botanists in phenology, which can be defined as the science of the relations between climate and periodic biological phenomena, has been active for years. In 1915, Lamb (g) published in chart form for a great many species the time of leafing, full foliage, flowering, seed ripening, seed falling, and leaf falling. In 1953, Duffield (5) revised an earlier publication, giving pine pollen collection dates with data on annual and geographic variation based on observation at the Institute of Forest Genetics in California. He states that Pinus ponderosa on the west slope of the Sierra Nevada show a difference of 8days in pollen collection per 1, ooo-feet difference in elevation, and that his figure agrees moderately well with Hopkins' (5) constant of 4 days for each 400-feet difference in elevation. The order of bloom of trees and shrubs at the Arnold Arboretum has been given by Wyman A method for describing and comparing blooming seasons has been given by Anderson and Hubricht(1).

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Growth Studies in Forest Trees: I. Pinus Rigida Mill; II. Pinus Strobus L Little stress was put on the study of secondary root thickening in the present investigation. Only one cutting was taken, on April 27, 1910, for purposes of comparison, so that no reliable deductions can be made. I At this time cambial activity was not manifest, although it must have been in process throughout the aerial portion with the possible exception of the apical shoot. T. Hartig (8) claimed that cambial awakening in the roots is much later than in the aerial portions. He gave midsummer as the time of first inception and said it continued far into October. Whether the same applies to Pinus rigida further investigation only can decide. Suffice it to say, however, that the growth in thickness of roots must not be confused with growth in length. The latter is manifest often as early as March and continues throughout the season. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2012-12-06 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.
