Phytochemical screening of ten different locally available plant parts was done in methanol extract. Tannin, quinine, terpenoid, flavonoid, steroid, alkaloid, cardiac glycoside, glycoside, volatile oils, etc were the phytoconstituents found in plants. The study of the effect of phytoconstituents in the germination of Pisum sativum seeds revealed that the phytoconstituents present in plant extracts showed the cytotoxic effect in living cells i.e. in germinating Pisum sativum seeds. The phytoconstituents present in the plant extract showed an effect on cell proliferation and growth. Hence these plants could be used to develop drugs against cancer cells and also may be effective against microbes and bacteria

SUMMARY Two species of Crotalaria, C. juncea L., a fibre‐yielding plant, and C. sericea Retz., have been grown in a glasshouse at three different light‐intensities. Comparisons have been made of their rates of increase in dry weight, relative growth rate, leaf area ratio, specific leaf area, leaf weight ratio, net assimilation rate, the ratio a of Whitehead & Myerscough and shoot/root ratio. C. sericea appears to be the more shade‐tolerant because its increased leaf area ratio compensates for a reduced net assimilation rate and so maintains the level of its relative growth rate.

Summary The growth of Crotalaria juncea L. and C. sericea Retz. under 8, 10, 12, 14 and 16 h daylengths was studied with respect to dry wt accumulation, leaf area increase, RGR, LAR, SLA, LWR, NAR, the value of a (ratio of mean relative growth rate to mean relative rate of leaf area increase) and S/R ratio. In both species, dry wt and leaf area increased up to 14 h daylength above which these features of C. juncea declined. The higher trend maintained in C. sericea suggests this is of selective value to a ruderal. C. sericea is characterized by a narrower range of values under the varying photoperiods. Strict comparison in terms of LAR is not possible owing to ontogenetic drift. In terms of RGR and NAR, C. sericea shows greater uniformity in all photoperiodic regimes. Values of a for this species also show a narrower range. All these are suggestive of its greater capacity than C. juncea to survive ecological vicissitudes in natural habitats.

This article presents a study on procedural terrain generation using Perlin noise in the Unity game engine, building upon prior research and established techniques [1,2]. The objective of the this study is to create realistic and visually appealing landscapes by leveraging algorithmic generation [3]. By utilizing a two dimensional monochrome Perlin noise map, the algorithm generates terrains with organic features such as hills, valleys, and mountains [4]. The research employs the Unity game engine, which offers a wide range of tools and technologies for implementing procedural generation algorithms [5]. The performance analysis conducted during this study yielded important insights. The execution time test revealed that the algorithm's execution time increased significantly with larger grid sizes, emphasizing the need to consider the scale and resolution of the terrains [6]. This finding highlights the trade-off between generating detailed terrains and the time required for the algorithm to complete its computations. Additionally, the memory usage test demonstrated a quadratic relationship between memory usage and grid size, indicating the necessity of efficient memory management [7] for generating higher-resolution terrains. Optimizing memory usage is crucial to avoid excessive consumption and ensure efficient resource utilization. These findings from the performance analysis provide valuable guidance for optimizing and refining the algorithm discussed in this article. Techniques such as algorithmic refinements, parallelization [8,6], and memory optimization strategies can be employed to reduce execution times and minimize memory overhead. By understanding the algorithm's performance characteristics and leveraging the insights gained from the analysis, developers can make informed decisions to generate visually compelling and diverse landscapes within the Unity game engine.
