PLANTS}, volume={8}, url={https://journals.innovareacademics.in/index.php/ajpcr/article/view/6643}, abstractNote={<p>Objectives: 3,7-dihydroxy 3′,4′ orthodihydroxy flavone isolated and identified from 50% aqueous ethanolic extract [5] and tested positive in antifungal<br />bioassay against Fusarium oxysporum ciceri [6] was taken up for further detailed analysis of the antifungal property for in vitro study in relation to<br /> Pisum sativum L. plants. The study incorporated a comparison of some morphological parameters such as root, shoot, internode, petiole length,<br />leaf and leaflet length, leaf and leaflet number/leaf, the total number of flower/plant, pod/plant, and seeds/pod.<br />Methods: Seeds of P. sativum L. plants were taken up as experimental material for in vitro studies. Six different sets were maintained by presoaking<br />the seeds with water, 3,7-dihydroxy 3′,4′ orthodihydroxy flavone, and fungicide for 3 hrs. The seeds were grown in pot cultures. At seedling stage,<br />three sets, one from each treatment, were exposed to fungal inoculum following soil drenching method. At the 21<br />st<br /> day, 42<br /> day of age,<br />the above-mentioned parameters were studied.<br />Results: Results indicated increased growth of internode, petiole, and shoot length in the plants which were administered with the 3,7-dihydroxy<br />3′,4′ orthodihydroxy flavone. The fungus infested plants exhibited reduced growth of internode, petiole, and shoot length. However, griseofulvin, a<br />popularly used fungicide showed inhibition of growth of all the parameters in healthy as well as in the infected plants. Flowering time was delayed in<br />the infested plants. Remarkably again, administration of the plant extract quickened the flowering time as similarly as in the healthy plants. Finally, the<br />number of seeds per pod in the plant also showed the same promising picture. The 3,7-dihydroxy 3′,4′ orthodihydroxy flavone treated plants showed<br />higher number of seeds a pod when administered to the healthy and infected plants.<br />Keywords: Fungicide, Inhibition, Inoculums, Infestation.<br /><br /></p>}, number={6}, journal={Asian Journal of Pharmaceutical and Clinical Research}, author={Das, Neela and Chatterjee, Padma}, year={2015}, month={Nov.}, pages={269–272} }
