BACKGROUND AND AIMS Considerable variation in seed size commonly exists within plants, and is believed to be favoured under natural selection. This study aims to examine the extent to which seed size distribution depends on the presence of competing neighbour plants. METHODS Phaseolus vulgaris plants rooting with or without a conspecific neighbour were grown in soil with high or low nutrient ...

background: this article was to present the sampling and measurements methods and the main preliminary findings of the kercadr cohort study (first round) in an urban and peri-urban setting, kerman, southeastern iran2009-11. method: 5900 (3238 female) people aged between 15 to 75 years were recruited in the household survey by non-proportional to size one-stage cluster sampling. trained internal...

To facilitate the search for candidate telomerase inhibitors, we exploited the database of the disease-oriented screening program (DOS) available in our facility by using COMPARE analysis. In primary and arbitrary screening, we were able to identify the alkaloid berberine as a moderate inhibitor with 50% inhibition at approximately 35 microM. Using this alkaloid as a seed compound in COMPARE re...

environmental conditions including metrological parameters (precipitation, temperature, humidity and etc.) various stresses and nutrition, could affect  germination and  seeds vigor during of development, ripping and leven after harvesting of soybean seed. for this, experiments of completely randomized design ( as nested)by four replications were performed in seed laboratory of gorgon universit...

introduction: sexual dimorphisms in biological structures such as brain and behaviour have been widely recognized in animals and humans. the purpose of this study was to examine whether there are sex differences in the size of the cerebellum with other body traits, such as the head, tail and brain. methods: twelve grasscutters comprising of 6 males and 6 females were used in this study. each br...

This research has been done to examine the effect of bio-priming on germination parameters related to seeds of canola cultivar (Hayola 401) under high salinity as factorial in seed laboratory of Shahed University based on a Completely Randomized Design (CRD) in three replications. Experimental factors included bio-primin...

A new region growing algorithm is proposed for the automated segmentation of three-dimensional images. No initial parameters such as the homogeneity threshold or the seeds location have to be adjusted. The principle of our method is to build a region growing sequence in increasing the maximal homogeneity threshold from a very small value to large one. On each segmented region, a 3D parameter wh...
