Microsporogenesis of Apricot Cultivars in Hungary
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2013 Like all phenological processes, microsporogenesis is mainly determined genetically, but its phenotypical expression is greatly influenced by environmental factors, particularly the temperature.

Microsporogenesis of peach (Prunus persica L. Batsch) varieties
International Journal of Horticultural Science, 2002 Bud dormancy during winter is a critical factor in peach production in Hungary. The yield is determined basically by the survival rate of flower buds during winter frosts and by their ability to develop normal floral organs.

Genome, 1989 The use of maize (Zea mays L.) pollen for basic scientific research has been well documented, but the progression of clear cytological features of maize microsporogenesis has not been fully documented. This study was undertaken to identify cytologically the different developmental stages of maize pollen and to correlate them with morphological ...

Microsporogenesis and Embryogenesis in Quercus [PDF]
Botanical Gazette, 1964 Representative species from two subgenera in the genus Quercus were examined for floral structure and phenology, microsporogenesis, and embryogenesis. The species selected for investigation were: Quercus alba in the Lepidobalanus subgenera, and Quercus coccinea and Quercus ilicifolia from the Erythrobalanus group.

Spikelet sterility in rice genotypes affected by temperature at microsporogenesis [PDF]
Revista Brasileira de Engenharia Agrícola e Ambiental, 2017 This study evaluated the effect of temperatures during the phase of microsporogenesis on spikelet sterility of paddy rice and identified genotypes tolerant to low temperatures at this growth stage.

Microsporogenesis and pollen formation in cassava
Biologia plantarum, 2011 This article describes the complete microsporogenesis and pollen formation in cassava (Manihot esculenta Crantz) at the various developmental stages (pollen mother cell, meiosis, tetrads, early free spore, mid uninucleate, late uninucleate, binucleate and mature pollen grain).

Polyamines in Pollen: From Microsporogenesis to Fertilization [PDF]
Frontiers in Plant Science, 2016 The entire pollen life span is driven by polyamine (PA) homeostasis, achieved through fine regulation of their biosynthesis, oxidation, conjugation, compartmentalization, uptake, and release. The critical role of PAs, from microsporogenesis to pollen-pistil interaction during fertilization, is suggested by high and dynamic transcript levels of PA ...

Patterns of amyloplast distribution during microsporogenesis in Tradescantia, Impatiens and Larix
Acta Societatis Botanicorum Poloniae, 2014 During the meiotic prophase I in Tradescantia and Impatiens microsporocyte becomes temporarily asymmetric, with excentrically situated nucleus and all amyloplasts gathered in a dense group close to the nuclear envelope..

High temperatures during microsporogenesis fatally shorten pollen lifespan [PDF]
, 2022 Many crop species are cultivated to produce seeds and/or fruits and therefore need reproductive success to occur. Previous studies proved that high temperature on mature pollen at anther dehiscence reduce viability and germinability therefore decreasing ...
