Revisions in the technique of epi-illumination light microscopy for the study of floral and vegetative apices
TLDR
Improvements in epi-illumination light microscopy have resulted in micrographs of better resolution and subsequently in greater flexibility in the study of floral and vegetative apices, and the correlation of this technique with others such as scanning electron microscopy and serial sectioning is discussed.
Potential and realized rates of vegetative reproduction in Spirodela polyrhiza, Lemna minor, and Wolffia borealis
TLDR
The rate of vegetative propagule development was estimated in three duckweed species, Spirodela polyrhiza, Lemna minor, and Wolffia borealis, by measuring the number of daughter fronds produced over the life span of mother fronds, finding different rates of propagule production likely represent different reproduction strategies.
The biology of Canadian weeds. 124. Hydrocharis morsus-ranae L.
TLDR
European frog-bit (Hydrocharis morsus-ranae L.), a free-floating, stoloniferous aquatic, is native to Europe and parts of Asia and Africa, and has spread throughout much of the central and southwestern parts of southern Ontario, and further into northern New York and Vermont and eastern Michigan.
Morphological and anatomical development in the Vitaceae. VI: Cissus antarctica
TLDR
The developmental morphology of Cissus antarctica Vent, was followed from seed to seed, and both leaves and unco...
Genealogy and gene flow among annual domesticated species of Cucurbita
TLDR
Allozyme data was used to address questions of genealogy, interspecific gene flow, and allelic diversity for 23 commercial cultivars and 17 indigenous landraces of C. mixta, C. moschata, and C. pepo, indicating relatively homogeneous despite morphological heterogeneity.
Development of the axillary bud complex in Echinocystis lobata (Cucurbitaceae): interpreting the cucurbitaceous tendril.
TLDR
It is concluded that the tendril and other organs formed by the ABC are lateral branches of equal morphological value and the basis for continuing comparative and functional morphological studies.
The influence of mycorrhizal colonization on the vegetative growth and sexual reproductive potential of Lythrum salicaria L.
TLDR
Investigation of the influence of the arbuscular mycorrhizal fungus, Glomus aggregatum Schenck and Smith emend, on the vegetative growth and sexual reproductive potential of L. salicaria found some aspects of purple loosestrife morphology did change.
Primary Vascular Patterns in the Vitaceae
TLDR
Vegetative characters such as shoot architecture and primary vascular pattern should prove useful in phylogenetic analyses of this architecturally unique family.
Increased image depth for epi-illumination microscopy
TLDR
Using digital editing, the depth of field for epi-illumination micrographs obtained for a number of shoot apices is enhanced and the microscope’s usefulness is increased as an alternative for conventional scanning electron microscopy.
Shoot Development and Evolution in Pistia stratiotes (Araceae)
TLDR
Understanding shoot development in flowering shoots has provided an explanation for the architecture of vegetative Pistia shoots, a series of repeating foliage leaves and reduced leaves that appear to be sterile (monopodized) shoots and have likely evolved from the sympodial flowering shoot system.
