Proc. 98th <strong>India</strong>n Science Congress, Part II : Abstracts of Oral/Poster Presentation<br />
Application of pesticide compounds to soil affected the germination, shoot and<br />
root growth, nodulation and N- content in different ways. 2,4-D completely inhibited<br />
seed germination at 1500 µg/ml. In streptomycin, Aureofungin, Thiram, Carbofunran,<br />
Thiodan, Hexacap, Difolatan and calixin less than 50% germination was observed.<br />
In case of RH-124 and Calixin seeds were germinated but did not survive after 30<br />
days at 1500 µg/ml and 80ppm respectively. In Dithane Z-78, Ceresan, Dithane M-<br />
45, Blitox, Blitane, Brassicol, Topsin-M, RH-124, Bavistin, Disystan, Dasanit and<br />
Hexafeb 50-90% seed germination was observed. Rovral give 100% germination.<br />
Shoot length was stimulated by Bavistin, Blitox, Brassicol, Ceresan, Dithane Z-78,<br />
Hexacap and Disystan while it was inhibited by other compounds. Similarly<br />
stimulation of nodule formation was seen in Bavistin, Blitox, Brassicol, Ceresan,<br />
Rovral and Thiram. Consequently increased due to these compounds. Difolatan,<br />
Hexafeb, Thiram and Dasanit, however, delayed flowering period.<br />

A number of fungal forays were undertaken in the past decade to various<br />
localities of Punjab, with an aim to collect the agarics from the wild. As a result<br />
of these forays, 24 collections were found to be falling under the 10 species of<br />
genus Psathyrella (Fr.) Quél. of family Psathyrellaceae. The collections were<br />
taxonomically worked out for their macroscopic and microscopic details. The 10<br />
species of Psathyrella included in this paper are P. naivashaiensis Pegler var.<br />
macrospora, P. singeri Smith, P. incerta (Peck) Smith. , P. longistriata (Murrill)<br />
Smith, P. obtusata (Fr.) Smith, P. moshiana Pegler, P. lithocarpi Smith, P.<br />
spintrigera (Fr.) Konr. & Maubl. , P. atroumbonata Pegler, and P. candolleana<br />
(Fr.) Maire. . Out of these, first six are first time reports from <strong>India</strong> and one new<br />
variety, namely P. naivashaiensis Pegler var. macrospora has been proposed. For<br />
all these taxa, the taxonomic details are given. P. lithocarpi is being reported for<br />
first time from North <strong>India</strong> while the other three species are re-reported.
