A taxonomic aid arising from pollen grains of Cestrum L. and Solanum L. (Solanaceae): differences in ornamentation and aperture
(2022-01-01)
Solanaceae is represented by herbs, shrubs, trees and climbing plants and has cosmopolitan distribution, with a large number of native species in the Neotropical region. This study aimed to characterize the pollen morphology ...
Pollen types of Sapindaceae from Brazilian forest fragments: apertural variation
(Soc Botanica Brasil, 2020-04-01)
Morphological variations in angiosperm pollen grains may aid in the differentiation of families, genera and species. Sapindaceae pollen morphology holds promise for the recognition of taxa of this cosmopolitan family, which ...
Pollen morphology of Fridericia Mart. (Bignoniaceae) from Brazilian forest fragments
(Soc Botanica Sao Paulo, 2014-03-01)
A pollen morphology study of 10 Brazilian native species of Fridericia (Bignoniaceae) from forest fragments was performed using light microscopy and scanning electron microscopy, in search of new characters that might ...
Pollen morphology and availability of pollen and stigma in Syzygium (Myrtaceae)
(Soc Brasileira Fruticultura, 2019-01-01)
The present study aimed to describe the pollen morphology in three species of Syzygium, to test pollen availability and stigma receptivity. The pollen was analyzed by light and scanning microscopy to show the detailed ...
Pollen morphology of Rutaceae from Brazilian forest fragments
(2018-01-02)
This paper presents pollen morphology of 12 native Brazilian species of Rutaceae from forest fragments of São Paulo, Brazil. The aim of this research is to expand the morphological knowledge of the species, thus contributing ...
Pollen starch reserves in tomato relatives: Ecophysiological implications
(Taylor & Francis As, 2007-12)
The presence or absence of starch in microspore development and in pollen grains was recorded in eleven wild tomato species (Solanum sect. Lycopersicon) and two close relatives (S. lycopersicoides and S. sitiens). In all ...
Pollen morphology of Malpighiaceae from Brazilian forest fragments
(2015-06-19)
The pollen morphology of 12 Brazilian native species of Malpighiaceae from forest fragments was investigated in search to expand the morphological knowledge of the species analyzed thus contributing to its palynology, ...
Impact of pollination on sunflower yield: Is pollen amount or pollen quality what matters?
(Elsevier Science, 2015-05)
•We tested the effect of amount and quality of pollen delivered to stigmas on three yield components of sunflower.•Both amount and quality of pollen arriving to sunflower stigmas influence grain set.•High amounts of a ...
Pollen and stigma morphology of some Phaseoleae species (Leguminosae) with different pollinators
(WILEY-BLACKWELL, 2011)
Pollen transport to a receptive stigma can be facilitated through different pollinators, which submits the pollen to different selection pressures. This study aimed to associate pollen and stigma morphology with zoophily ...
Modern pollen source and spatial distribution from surface lake sediments in the southwestern Pampa grasslands, Argentina: Implications to interpret Holocene pollen records
(Elsevier Science, 2020-06)
In the Pampa grasslands of Argentina nothing is known about the transport, deposition and spatial distribution of pollen in lakes. To analyze and understand how well lake surface sediment pollen assemblages reflect the ...
