Disturbances in microsporogenesis and pollen grain development in Gagea lutea (L.) Ker. Gaw.
Acta Agrobotanica, 2012 The meiotic division of microsporocytes and pollen grain development in Gagea lutea (L.) Ker.-Gaw. (Liliaceae) with fluorescence microscope (excitation light 400 nm) was observed after squashing the anthers in DAPI solution (fluorochrom dying DNA). Up to

Fungitoxicity in pollen grains [PDF]
Grana, 1983 Abstract While screening 45 samples of pollen suspension for their antifungal activity against Helminthosporium oryzae and Alternaria alternata, only that of Lycopersicon lycopersicum exhibited absolute toxicity against both the pathogens. The maximum inhibitory dilutions were found to be 1: 200 and 1: 500 (w/v) against A. alternata and H.

Taxonomic significance of pollen morphology of Pterocephalus plumosus (Caprifoliaceae) [PDF]
Botanica Serbica, 2022 Comparative palynological studies of Dipsacaceae s.str. show considerable diversity in the pollen grain morphology of its representatives. The aim of this research was to provide more detailed palynomorphological data on selected taxa whose pollen grains

Chloride fluxes in lily pollen tubes: a critical reevaluation
, 2004 Microelectrodes, made from a Cl?-selective liquid ion exchanger previously used to measure putative Cl- fluxes in Lilium longiflorum pollen tubes, were characterized. The electrodes were poorly selective, possessing only about 10-fold selectivity for Cl?

Ultramicroscopic Characterization of Mature Pollen Grains of Habenaria sagittifera
Horticultural Plant Journal, 2016 Transmission electron microscopy was conducted to characterize the mature pollen grains in the massulae of Habenaria sagittifera at anthesis to understand its ultramicroscopic features of mature pollen grains of this species.

Perspectives on deciphering mechanisms underlying plant heat stress response and thermotolerance
, 2013 Global warming is a major threat for agriculture and food safety and in many cases the negative effects are already apparent. The current challenge of basic and applied plant science is to decipher the molecular mechanisms of heat stress response (HSR ...

Pollen-grains in the Air [PDF]
Nature, 1874 I AM very sorry to find that, owing to my absence from home at the time, a question addressed to me by Mr. A. W. Bennett, in NATURE, vol. ix. p. 485, has escaped my notice hitherto and remained unanswered. Mr. Bennett, alluding to my letter on “Microscopic Examination of Air” (NATURE, vol. ix. p. 439), asks on what ground I refer the “triangular pollen”
