Pollen Biology

Allergic diseases are caused by hypersensitivity of the immune system to a certain environmental exposure. Many different agents may induce an allergic reaction. This chapter concerns reactions to pollen. Although allergies to animals, for example dogs and cats, may be considered as part of nature-induced allergy, the focus here is on vegetation. Allergic reactions to pollen depend on the type of pollen, biological properties, location, and individual factors. Changes in our immune systems, our living environments and lifestyles, and climate change may play a role in the increasing prevalence of pollen allergies. This chapter contains three major sections: first, the basics of pollen biology are outlined; secondly, pollen’s impact on human health are introduced; and finally, the chapter includes a section on how practitioners and policymakers can plan our cities to be green, and yet limited in allergenic exposure.

Pollen Biology

Plant reproduction meetings often deal either with pre-fertilization processes such as flowering and pollen biology or post-fertilization processes such as embryogenesis and seed development. The Biochemical Society Focused Meeting entitled ‘Regulation of Fertilization and Early Seed Development’ was organized to close this gap and to discuss mechanistic similarities and future research directions in the reproductive processes shortly before, during and after fertilization. As an outcome of the workshop, invited speakers and a few selected oral communication presenters contributed focused reviews and technical articles for this issue of Biochemical Society Transactions. We provide here a short overview of the contents and highlights of the various articles.

This paper presents the phenology of seven taxa of the genus Magnolia L., pollen biology on germination and storage conditions, seed productivity, germinating ability of seeds and its dependence on stratification and germination conditions. It has been found that  M. kobus DC, M. kobus var. boreales Sarg., M. obovata Thurb., M. officinalis Rehd. et Wils., M. salicifolia (Sieb. et Zucc.) Maxim., M. sieboldii K. Koch. and M. tripetala L. in cultivated condition produce pollen at a low viability rate (9.4 - 31.7%). Real seed productivity of the taxa being studied is less than their potential productivity. However, M. obovata, M. officinalis and M. tripetala are characterized by high seed germinating ability, up to 94%. Optimal germination conditions for seeds of M. tripetala, M. officinalis and M. obovata require protected ground (greenhouse) and stratification at 4ºC during 30 days. The high germinating ability of M. sieboldii seeds in the open ground is explained by stratification duration and temperature required for this species. Sarcotesta effects on higher seed germinating ability have been observed in M. obovata only.DOI: http://dx.doi.org/10.3329/bjpt.v20i2.17390Bangladesh J. Plant Taxon. 20(2): 163-170, 2013
