Host range, serological and electron microscope studies of phages of Agrobacterium tumefaciens (Smith and Townsend) Conn

Creator:: Buangsuwon, Pairoj
Abstract:: Phages of crown gall bacteria were among the first to be isolated and certain properties of these phages have been studied by a number of investigators. However, several important characteristics have not been studied in detail. The present investigation was made in order to determine the major sources of phages...

Comparative wood anatomy of the Fagaceae of Taiwan

Creator:: Lee, Chun-shu
Abstract:: Many species of the Fagaceae have been variously interpreted on the basis, primarily of external morphological characteristics. The objectives of this study are to elucidate generic and specific characteristics of the wood of Fagaceae and to attempt to obtain evidence regarding taxonomic relationships among some of the species occurring in...

Development of the storage organ of Brassica campestris L.

Creator:: Larson, Ann Marie
Abstract:: Developmental changes in the storage organ of Brassica campestris L. were followed from the organization of the embryonic radicle and hypocotyl to the mature storage organ. Three independent primary meristems gave rise to the cortex, the stele, and the root cap-epidermis. The primary development is typical of the Cruciferae. Cambial...

Anatomical studies of Pinus ponderosa Laws : infested by Elytroderma deformans (Weir) Darker

Creator:: Wirtz, Felicia Pietrykowski
Abstract:: Pine needle blight of Pinus ponderosa Laws. caused by Elytroderma deformans (Weir) Darker is recognized by changes in the needles, in the bark and in the development of the branches. Anatomical studies of the host-parasite relation have been made previously on young pine tissue up to four years of age...

Comparative anatomical study of three species of Microseris

Creator:: Soedjono, Estiti Harti
Abstract:: Three growth forms of the genus Microseris, of the tribe Cichorieae, family Compositae, were compared with respect to their anatomical structure. The purpose of this study was to clarify lines of evolutionary specialization in the genus. Two of the three species studied, M. laciniata and M. borealis, are perennials, while...

Anatomical changes in the secondary phloem of grand fir (Abies grandis (Dougl.) Lindl.), induced by the balsam woolly aphid (Adelges piceae Ratz.)

Creator:: Saigo, Roy Hirofumi
Abstract:: The balsam woolly aphid (Adelges piceae Ratz.) feeds by inserting its stylets intra- and intercellularly into the cortex or outer phloem of the true firs. While feeding, the aphid injects into the bark an unknown stimulatory substance which affects the adjacent cortical parenchyma cells, the activity of the vascular cambium...

Seasonal pattern of secondary growth in stems of northern white spruce (Picea glauca (Moench) Voss)

Creator:: Gregory, Robert A.
Abstract:: Cambial activity in white spruce stems in Alaska was observed from April, 1964 to September, 1965 in over 300 samples taken from 50- to 60-year-old natural stands. Mitotic index was used as a measure of the rate of periclinal division of fusiform cells in the cambial zone. Anticlinal divisions are...

Root initiation and differentiation in Pseudotsuga menziesii (Mirbel) Franco

Creator:: Bogar, Gerald Dale
Abstract:: Tissue differentiation of the primary root and its associated laterals is reported. Secretory elements are the first of the primary tissues to mature. They appear to be located between the precursory phloem and pericycle in the primary root, but are more closely associated with the pericycle in long lateral roots....

Physiology of senescence of the shoot apex in Pisum sativum L.

Creator:: Ecklund, Paul Richard, 1941-
Abstract:: Shoot apex senescence is defined as the collective progressive and deteriorative processes which ultimately terminate the functional life of the shoot apex. Senescence of shoot apices of Pisum sativum L. 'Alaska' as measured by cessation of stem elongation was delayed by removal of flowers and by treatment with gibberellin A₃...
