Abstract

: A floristic survey in Firozabad district was carried out from three selected sites which are 15-20 km away from each other. The main objective behind the field study was to find out angiospermic species which may shed large number of pollen in the atmosphere and to note their specific pollination period and mode of pollination which was useful criterion in the identification of atmospheric pollen. We studied variations in concentration of airborne pollen and other particles of biological origin which are collectively known as Primary Biological Aerosol Particles (PBAP) in those three sites. During the annual cycle the frequency of pollen in the air was different in different seasons. It might be due to local climatological influence on flowering of plants. The lowest concentration of pollen was observed in winter season. On the basis of mode of pollination in winter season 65.99% anemophilous, 27.82% entomophilous and 3.58% amphiphilous species were found. Maximum plants bloom, during spring and rainy season followed by summer and winter season.

北方邦firozabad地区夏季被子植物空气传播花粉的传粉方式分析

:在Firozabad地区从三个相距15-20公里的选定地点进行了植物区系调查。野外研究的主要目的是寻找在大气中大量传播花粉的被子植物物种，并记录其特定的授粉周期和授粉方式，为大气花粉鉴定提供依据。我们研究了这三个地点空气中花粉和其他生物来源颗粒的浓度变化，这些颗粒统称为初级生物气溶胶颗粒(Primary biological Aerosol particles, PBAP)。在年循环中，空气中花粉的频率在不同季节有所不同。这可能是由于当地气候对植物开花的影响。花粉浓度在冬季最低。从传粉方式看，冬季风媒占65.99%，虫媒占27.82%，两栖占3.58%。植物开花最多，在春季和雨季，其次是夏季和冬季。
