To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...

Twelve cultivars of bambara groundnut were sown for evaluation of variability and genetic correlation among agronomic characters and seed yield in 2004 and 2005 in a randomized complete block design with three replications. Combined analysis of variance revealed highly significant effects (p<0.05) for genotypes (G), year (Y) and G x Y interaction for most characters evaluated. Estimates of geno...

In 2007 Jedwab and Parker proposed [10] that the natural viewpoint for a Golay complementary sequence is as a projection of a multi-dimensional Golay array. In 2008 Fiedler, Jedwab and Parker [5] used this viewpoint to show how to construct and enumerate all known 2-phase Golay sequences of length 2, starting from two sources of Golay seed pairs. The first source of seed pairs is the trivial Go...

We construct pseudorandom generators with improved seed length for several classes of tests. First we consider the class of read-once polynomials over GF(2) in m variables. For error ε we obtain seed length Õ(log(m/ε)) log(1/ε), where Õ hides lower-order terms. This is optimal up to the factor Õ(log(1/ε)). The previous best seed length was polylogarithmic in m and 1/ε. Second we consider produc...

Variation in pod and seed yield among twelve cultivars of Bambara groundnut was investigated in 2004 and 2005 cropping seasons. The mean performance revealed that BG7004AS despite its recorded low number of pods per plant, had the highest 100 seed weight, pod width, pod length, seed width and seed length, followed by BG7002AS, BG7009BS and BG70010AS, which had the best yield and yield component...

Vigour was measured using computer-aided analysis of digital images in six seed lots of Impatiens that differed in vigour but retained greater than 86% standard germination. Seed lots that differed in initial seed vigour were selected based on the commercially used Ball Vigour Index and vigour independently assessed using saturated salts accelerated aging tests. Digital images were captured fro...

This paper presents a unique application of computer vision methods designed to detect germination of lettuce seeds under controlled environment. Two steps involved in this application are image acquisition and image analysis which uses image skeletonization and other image processing algorithms. Seed images are converted to binary images followed by extraction of seed skeletons, which are used...
