An Induction of artificial polyploidy by 0.4% aqueous solution of Colchicine has been successfully made in Cassia tora . The data obtained from the experimentally treated materials have been further analysed for all the implications to understand the effect of Colchicine on the Chromosome structure, and function. The tetraploids showed n = 26 bivalents and different combinations of univalent and multivalent, the percentage of quadrivalents being the highest Chromosome irregularities in PMCs of polyploids has been detected more frequently than normal diploid. The polyploids thus, raised did show autopolyploidy in nature. The chemical environment within the cell can change the meiotic behaviour of a species. The tetraploid plants showed a slower rate of growth, delayed flowering, thicker, darker and wider leaflet, and decreased stomatal frequency per unit area. This also showed larger stomata, increase in height, increase in number of lateral branching, bigger fruit, seed size and increase in the number of pollen grains with absence of exine. The pollen sterility increases as compared to diploid. It is thus clear that experimental induction by Chemical means (Colchicine) holds a clue for understanding the adaptability of the species in different environmental conditions.

The effect of Vermicompost on a medicinal plant of great economic significance has been monitored. The plant Andrographis paniculata L. of family Lamiaceae is widely used all over the world for its biologically active ingredients containing diterpenoid, flavonoids, and polyphenols. The effect of Chlorpyrifos along with Vermicompost has been monitored on this plant. On one hand treatment of Vermicompost has been made to stimulate the growth and development of the test plant, an attempt has also been made to study the growth of the test plant under the stress condition of Chlorpyrifos. It has been noticed that the germination of the test plant increases with the lapse of time in the presence of Vermicompost as 100% growth is attained in 10 days. This value is 42.9% without Vermicompost during the same period of time. Low concentration of Chlorpyrifos (01%) also favors germination up to the extent of 50% in presence of Vermicompost the value is 25% in presence of (01%) of Chlorpyrifos but without Vermicompost. There has been marked reduction in the rate of germination in presence of 02% of Chlorpyrifos in the atmosphere of Vermicompost the germination is reduced by 25% this is further reduced to 15% in 03% of Chlorpyrifos. This value has been 20% and 10% in the presence of 02% and 03% of Chlorpyrifos in presence of Vermicompost. Plant height has also been taken into account for such type of treatment and it shows that with a lapse of time the plant height increases with 15% of Vermicompost. This rising trend continues even in 01%, 02% and 03% of Chlorpyrifos. An increase in the number of leaves means an increase in productivity. A similar trend of increase as described in germination and plant height has been also recorded in the emergence of leaves. With the lapse of time, the number increases during various treatments made. Test plants under treatment exhibited different kinds of morphological variations. As a prelude leaves of different treatments were used for calculating the area of leaves. This feature has also been found to be similar to the results described above i.e. with the increase in days of treatment the area of the leaf increases. The result described above has been presented below.

Agro-morphological characterization of crop is the basic criteria to provide fundamental information for plant breeding programs. An investigation was conducted in Agronomy farm of Institute of Agriculture and Animal Science, Lamjung Campus in alpha-lattice design with two replications. The objective of the study was to characterize thirty landraces of rice ( Oryza sativa L.) of Lamjung and Tanahun district based on 30 qualitative and 8 quantitative characters, recorded as per descriptor established by IRRI, Bioversity International and WARDA. The frequency distribution of qualitative characters were studied where panicle shattering, lemma & palea color, culm lodging resistance and Leaf senescence showed high variability. The maximum value, minimum value, coefficient of variation and Pearson correlation were analyzed to study quantitative characters. The coefficient of variation ranged from 5.4% (Grain Length: Breadth ratio) to 20% (Total Tillers) indicating that selection based on the characters showing higher variation is expected to be effective. The highest correlation was corresponded to the total tillers and effective tillers (r=0.978 ** ). Flag leaf length showed positive significant correlation with penultimate leaf length (r=0.674 ** ), total tillers (r=0.437 ** ), effective tillers (r=0.356 ** ) and Grain Length: Breadth ratio (r=0.430 ** ). UPGMA clustering of the genotypes was done where members of cluster IV were found to be more superior. Promising landraces were identified from different yield attributing characters like total tillers, total grains per panicle, 1000 grain weight, panicle length and filled grain percentage. Thus, the present study can be utilized for further rice improvement programs and can also be used for assessing genetic diversity among morphologically distinguishable rice landraces.

Cultivation of oyster mushroom ( Pleurotus ostreatus ) on the aquatic weed water hyacinth is an eco-friendly way of controlling and management of such a problematic weed. In the present work, water hyacinth has been used as a low-cost substrate in combinations with rice-straw of ratio 3:1 for the cultivation of P. ostreatus . The objective of this study was to cultivate oyster mushroom in water hyacinth compost degraded with lingo-cellulolytic fungi. The experiment was performed in control, before fungal treated compost and fungal treated compost. The data was analyzed on various aspects like completion of mycelium growth in different media like Potato dextrose agar media and water hyacinth media, the duration for spawn run, the appearance of pinheads, fruiting bodies and number of fruit bodies produced. The nutrient analysis was done in all types of fruit bodies. Aspergillus flavus treated compost took short duration (24 ± 1 days) and control sample compost took a long duration (27.3 ± 1.53 days) for fruiting. The highest production was recorded in Trichoderma sp. treated compost (68.8%) and lowest in control compost (30.7%). This study has successfully demonstrated the possibility of water hyacinth as a substrate in mushroom production and management of water hyacinth.

The aqueous (distilled water) and alcoholic (methanol) crude extract from the leaves of invasive alien plant species Ageratina adenophora and Ipomoea carnea ssp. fistulosa were evaluated against six human pathogenic bacteria, three Gram negative: Escherichia coli (ATCC 25922) , Klebsiella pneumoniaea (ATCC 15380) and Proteus mirabilis (ATCC 49132) and three Gram positive: Enterococcus faecalis (ATCC 29212) Bacillus subtilis (ATCC 6633) and Staphylococcus aureus (ATCC 25923) using disc diffusion method. Different concentrations of plant extracts (50 mg/ml, 100 mg/ml, 150 mg/ml, 200 mg/ml and 250 mg/ml) were applied and diameter of zone of inhibition (ZOI) of bacterial growth were recorded. Both plant extracts showed antibacterial activity against Gram positive and Gram-negative bacteria. Methanolic extract of plant extracts exhibited good activity against tested bacteria when compared to aqueous extract. Among tested plants I. carnea ssp . fistula was more active than A. adenophora . The zone of inhibition of bacterial growth increased with increasing concentrations. The demonstration of activity against all these organisms had shown that both alien invasive species; Ageratina adenophora and Ipomoea carnea ssp. fistulosa. can be used to produce raw materials/substances for further development of diverse antibiotics with broad spectrum of activity.
