Reproductive and vegetative morphology of Polyptera (Juglandaceae) from the Paleocene of Wyoming and Montana.
The morphology, systematics, and ecology of the extinct juglandaceous genus Polyptera are interpreted on the basis of infructescences, fruits, staminate catkins, pollen, and compound leaves from the Paleocene of Wyoming and Montana. The elongate infructescences of Polyptera manningii bear numerous helically arranged sessile fruits. The fruit is a pyramidal nut with a vascularized husk and a mul...
متن کاملRecent Advances in the Study of Apomixis in Juglandaceae
Walnut, Juglans regia L. is the most economically important member of the Juglandaceae family and is the most valuable nut crop in the world. Recently, it has increased greatly in acreage and in production. Although a number of research programs about plant apomixis have been carried out around the world, few were representd by the Juglandaceae. This paper presents a brief review of the current...
متن کاملInflorescence dimorphism, heterodichogamy and thrips pollination in Platycarya strobilacea (Juglandaceae)
BACKGROUND AND AIMS Unlike other taxa in Juglandaceae or in closely related families, which are anemophilous, Platycarya strobilacea has been suggested to be entomophilous. In Juglandaceae, Juglans and Carya show heterodichogamy, a reproductive strategy in which two morphs coexist in a population and undergo synchronous reciprocal sex changes. However, there has been no study focusing on hetero...
متن کاملMorphology and viability of castor bean genotypes pollen grains
The objective of this work was to characterize the morphology and viability of the pollen of 15 genotypes of castor bean (Ricinus communis L.) and to generate information that can assist in the selection of highly promising male parents for future use in genetic improvement programs aimed at producing seeds for oil extraction. Acetolysis and scanning electron microscopy was used to characterize...
متن کاملIsolation and characterization of 20 polymorphic microsatellite markers for Juglans mandshurica (Juglandaceae)1
UNLABELLED PREMISE OF THE STUDY Fifty microsatellite loci were developed for the endangered species Juglans mandshurica to investigate its genetic diversity and population structure. • METHODS AND RESULTS In all, 50 microsatellite markers were isolated from J. mandshurica, using the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) protocol. Twenty of these polymorphic marker...
