The present study is an attempt to investigate the Plant
Biodiversity of Batrasi Pass with special reference to its
Conservation status .The studies were conducted in different
seasons during the year during 2007 and 2008. The plants were
collected from different habitats, which were later dried and
preserved at Hazara University Herbarium for further investigation.
A total of 145 species are represented in the area including2
species of bryophytes, 4 species of pteridiophytes,5 species of
Gymnosperms, and 113 species of Angiosperms. Among the Gymnosperms
4 genera and 5 species are found whereas in Angiosperms 46 families
(21 species of Monocot belonging to 3 families, and 113 species
belong of Diocot belonging to 43 families) were collected from the
area.
Effects of various gamma rays i.e. .5, 1, 1.5, 2, 2.5, 3, 3.5, 4,
4.5, 5 kard were observed on the various genetic parameters of
sunflower (Helianthus annus L.). The difference in mean value due
to radiation doses were highly significant for radical length,
plumule length, number of roots and dry weight, while significant
in Germination percentage and Diameter of epicotyls. While the time
of germination fresh weight and moisture content percentage were
insignificant. The differences in mean values due to replications
shows highly significance for plumb length, while germination
percentage, diameter of epicotyls, radical length fresh and dry
weight were significant and the number of roots, time of
germination and moisture contents percentage were insignificants.
Peshawar Valley, the main drainage basin of Kabul River is widely
known for its fertile land, intact wetland and diverse cultural and
biological resources. This dissertation is an outcome of an effort
to record species diversity of unicellular Green algae from the
Valley. Sum of 10 genera with 70 species of Unicellular Green
Algae, Chlorophyta were collected and identified from different
localities of District Peshawar. The most frequent genus in term of
species was Tetraedron with 24 species (34.28 %). Other frequent
genera were Closterium 10 species (14.28 %), Cosmarium 9 species
(12.85%), Characium 9 species (12.85%) and Chlamydomonas 5 species
(7.14%). The genera Ankistrodesmus and Oocystis were represented by
4 species each (5.71%), Chlorella and Carteria 2 species each
(2.85%) and Closteriopsis only a single species (1.42%).
