Control of Acanthoscelides obtectus Say (Coleoptera: Bruchidae) in Phaseolus vulgaris L. seed stored on small farms—I. Evaluation of damage
TLDR
Three treatments effectively reduced A. obtectus damage below the economic threshold determined in this study, and the potential for small-farmer adoption of these and less successful treatments is evaluated. Expand
POLLINATION IN LUPINUS NANUS SUBSP. LATIFOLIUS (LEGUMINOSAE)
Floral morphology and phenology and the timing of stigmatic receptivity and pollen viability were studied to elucidate the mechanisms by which self-pollination in Lupinus nanus subsp. latifolius isExpand
THE MORPHOLOGY AND RELATIONSHIPS OF DALECHAMPIA SCANDENS (EUPHORBIACEAE)
TLDR
The similarity of the Dalechampia inflorescence to the cyathium of the Euphorbieae appears to be entirely superficial, and both reproductive and vegetative data suggest that Dalechampsia is related to taxa of tribe Plukenetieae. Expand
Ultrastructural Modifications Associated with Imbibition of the Soybean Radicle
TLDR
Observations indicate that the initial imbibition of water into radicle cells results in extensive membrane changes, and mitochondria and proplastids do not change in structure in dry and imbibed tissue. Expand
Anatomical aspects of abscission.
TLDR
Experimental studies on Coleus, Gossypium, and Phaseolus suggest that the experimental results can be explained on the basis of changes induced in levels of ethylene in the petiole, the experimental application of Ethylene becoming effective in expediting abscission only after the endogenous ethylene level in explants has declined. Expand
In dry pear (Pyrus communis L.) pollen, membranes assume a tightly packed multilamellate aspect that disappears rapidly upon hydration
TLDR
Results suggest that multilamellate membranes form as the plasma membrane, vesicles, ER, and double-membrane bound organelles undergo dehydration, and that upon hydration they rapidly resume normal unilameLLate structure. Expand
A morphogenetic study of leaf abscission in Phaseolus.
TLDR
Correlation of the time and the nature of these structural changes with the period of effectiveness of certain applied growth regulators provides some interesting insights into the nature the regulatory mechanisms in abscission. Expand
