production of high yielding hybrid cultivars is among the main objectives of breeding programs in sunflower and on evaluation of the combining ability of the inbred lines necessary to select for the appropriate parental lines for production of hybrid cultivars. this study was conducted to investigate the general and specific combining ability and the mode of inheritance for agronomic and seed q...

samples of grass pea seed (lathyrus sativus) were prepared and analyzed for some chemical composition and as well for their anti-nutritional factors. the rumen degradability coefficients and post ruminal digestibility of dry matter and crude protein of unheated vs. oven heated samples were determined, employing in situ and in vitro techniques. results indicated that grass pea seed contained a c...

Shortleaf pine (Pinus echinata Mill.) seed production was monitored for 4 yr in stands harvested by a range of evenand uneven-aged reproduction cutting methods. The fifty-two 35–40 ac stands were distributed throughout the Ouachita Mountains from central Arkansas to eastern Oklahoma. Seed crops were characterized as good, poor, poor, and bumper, averaging 109,000, 18,000, 5,000, and 379,000 sou...

The  genetic diversity of 50 sesame genotypes was studied by Mahalanobis D2 statistics. By using Tocher’s method, were grouped into nine clusters based on 10 economically important traits viz., days to flowering, 50% maturity, plant height, the number primary branches, secondary capsules per plant, seeds capsules, thousand seed weight and single yield. largest intercluster distance among f...

The relationship between osteoarthritic change and amyloid degeneration was studied in 116 joint capsules from osteoarthritic hip joints. Twenty-seven (23%) contained amyloid deposits. Twenty-eight joint capsules showed chondroid metaplasia in the fibrous part. Significantly more amyloid degeneration was found among these. Six joint capsules contained pyrophosphate crystals. Five of these were ...

Seed production is one of the least visible yet most important aspects of food and feed production. This part of the system is often taken for granted, even by the farmers who plant the seed. One of the reasons is that much of the seed in the United States is provided by the private sector, particularly for corn and soybean. Also, seed production is a technical process that requires in-depth kn...

Seed production of annual weeds persisting through cropping phases replenishes/establishes viable seed banks from which these weeds will continue to interfere with crop production. Harvest weed seed control (HWSC) systems are now viewed as an effective means of interrupting this process by targeting mature weed seed, preventing seed bank inputs. However, the efficacy of these systems is directl...

among the agricultural important factors, inputs are the most significant in agricultural production. this article aimed to examine the impact of government subsidy policies on production of one of the most strategic products, namely on production of one of the most strategic products, namely maize, in iran. to achieve this goal, panel data for the nine provinces of iran's major producers of ma...

LLE Review, Volume 92 167 In 1996 LLE began a research effort to make spherical capsules from polyimide material for use in direct-drive inertial confinement fusion (ICF) experiments. Previously, ICF capsules were made exclusively from glass, polystyrene, or an amorphous carbon–hydrogen solid solution referred to as “plasma polymer” or “glow-discharge polymer.”1 Polyimide was first proposed as ...
