BACKGROUND AND AIMS Silene dioica and S. latifolia experience only limited introgression despite overlapping flowering phenologies, geographical distributions, and some pollinator sharing. Conspecific pollen precedence and other reproductive barriers operating between pollination and seed germination may limit hybridization. This study investigates whether barriers at this stage contribute to r...

A digital image of a plant seed can be regarded as a two-dimensional object which can be measured in size, shape and color density during the development stage of germination by computer image analysis technology. Seed changes its biological structure passing from a quiescent stage to a proliferating one, and any morphological variation can be associated with the corresponding variation of seed...

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh to assess the effect of weeding on growth, yield and yield contributing characters of mungbean (Vigna radiata L.) cv. BINA mung4 during October 2011 to February 2012. The experiment was laid out in a randomized complete block design with four replications. The trial comprised seven tre...

This paper gives details of a series of low level image processing routines which successfully break an image into a set of coloured regions. The first stage in the process is multi-scale edge detection. A fixed set of different sized kernels are used with the results being put into a single ’edgeness’ image. A fixed lower threshold is applied to the edgeness image. A non-maximum suppression st...

We present a memory-based named-entity recognition system that chunks and labels named entities in a oneshot task. Training and testing on CoNLL-2003 shared task data, we measure the effects of three extensions. First, we incorporate features that signal the presence of wordforms in external, language-specific seed (gazetteer) lists. Second, we build a second-stage stacked classifier that corre...

Five common range forage including Agropyron intermedium, Bromustomentellus, Hordeum bulbosum, Cousinia bakhtiarica and Scariolla orientalis, weresampled during three phenological stages, from controlled rangeland stations over fivelocations in Chaharmahal and Bakhtiari province, Iran. All samples were chemicallyanalyzed for Crude Protein (CP%), in vitro Dry Matter Digestibility (DMD), OrganicM...

Background: Oat is mostly neglected crop for hybrid development due to its floral structure which results in high damage rate during hybridisation. Due the cumbersome acquiring a sufficient number of hybrids and subsequent backcrosses are difficult that lead lack much inheritance studies Oats. Methods: The procedure crossing used was almost identical by oat breeders conducted 2 years viz., 2019...
