Annual Report <strong>2008</strong>-09<br />
The fungi isolated from these disease specimens included Selenophoma, Phyllosticta,<br />
Pestalotiopsis, Cylindrocladium, Colletotrichum gloeosporioides, Fusarium,<br />
Exserohilum, Botryodiplodia, Curvularia, Alternaria, Cirrenalia and Dendryphiella.<br />
Two hitherto unrecorded Cytospora spp. causing stem canker and die-back in<br />
Sonneratia, and a Phellinus sp. causing decay in Rhizophora mucronata were recorded. Detailed<br />
studies on morphological and microscopic characteristics of Phellinus sp. revealed that the<br />
fungus was a new species Phellinus rhizophorae Mohanan. The soft rot fungi found associated<br />
with mangroves and their associates were Microporus, Microporellus, Hexagonia, Daedalia,<br />
Auricularia and Polyporus. Old stands of Excoecaria and Rhizophora were found affected by<br />
Auricularia, Microporus and Hexagonia.<br />
Twelve species of mangroves growing at Madakkara and Thazhekkavu were selected for the<br />
study of endophytic fungi. The species diversity (Shannon index) and species evenness of the<br />
endophyte assemblages were calculated. A total of 29 foliar fungal endophytes were encountered<br />
in different mangrove species and their colonization frequency ranged from 1 to 93.<br />
Protection of Tsunami-affected coastal areas by establishing bioshields through<br />
people's participation<br />
The project was taken up for establishing bioshields along coastal areas through<br />
people's participation and evaluation of performance and carbon sequestration<br />
potential of these stands. A mother nursery was established at Chendrappinni for<br />
raising the planting stock of casuarina and bamboos. The nursery beds were watered<br />
regularly and after 60 days, healthy seedlings in the mother nursery were<br />
transplanted into polythene bags of 12 cm x 18cm size, filled with red soil, sand<br />
and cowdung. The transplanted seedlings were watered regularly. For bamboos,<br />
1000 two-noded cuttings of Bambusa vulgaris were treated with 100 ppm solution<br />
of IBA were laid under soil in five nursery beds. Sprouting of new shoots started<br />
after six days. The nursery beds were watered regularly and after 60 days, the average<br />
height of sprouts was 45 cm. More than 1 lakh plants of Casuarina and 10000<br />
Bambusa vulgaris rooted cuttings were produced.<br />
