BACKGROUND Penumbra characteristics play a significant role in dose delivery accuracy for radiation therapy. For treatment planning, penumbra width and radiation field offset strongly influence target dose conformity and organ at risk sparing. METHODS In this study, we present an analytical and numerical approach for evaluation of the rounded leaf end effect on penumbra characteristics. Based...

The present study consists of 21 rice genotypes including one check variety that were evaluated in 2021 to genetic variability, correlation and path coefficient for thirteen quantitative characters. Observation recorded the variability parameters, yield its attributing traits. On basis mean performance MTU-1224 was found be superior grain per hill followed by, BPT-329, KNM-118 MTU-1001 give hig...

The grain yield of pearl millet has increased continuously in past decades through development hybrids and improved production practices. Elite inbred lines are crucial for innovating new germplasm/traits to break the plateau. Hence, 64 were evaluated assess extent genetic variability association among agronomic, physiological contributing traits. Analysis variance showed significant difference...

The glossy varieties (A14 and Jing 2001) and glaucous varieties (Fanmai 5 and Shanken 99) of wheat (Triticum aestivum L.) were selected for evaluation of developmental changes in the composition and morphology of cuticular waxes on leaves and spikes. The results provide us with two different wax development patterns between leaf and spike. The general accumulation trend of the total wax load on...

In this research, leaf area prediction model was developed for some leaf-used maize (Zea mays L.) cultivars namely Coluna, Luce, Maveric, Ranchero, TTM-813, Zamora and RX-788 grown in Black Sea region of Turkey. Lamina width, length and leaf area were measured without destroying the leaf to develop the models. The actual leaf areas of the plants were measured by PLACOM Digital Planimeter and mu...

Ribonucleases (RNases) degrade RNA and exert a major influence on gene expression during development and in response to biotic and abiotic stresses. RNase activity typically increases in response to pathogen attack, wounding and phosphate (P(i)) deficiency. Activity also increases during senescence and other programmed cell death processes. The air pollutant ozone (O(3)) often induces injury an...

this research was designed to identify garlic (allium sativum l.) bolting clones and determining the relationship between their morphological traits and bolting capacity by using statistical methods of analysis of variance, comparison of means, correlation coefficients, factor analysis, stepwise regression, path analysis and cluster analysis. traits including flowering ability, number, length a...
