The Nymphoides peltata (N. peltata) population has shown rapid expansion in Lake Taihu, China, in recent years. The core question is whether N. peltata seeds have contributed to the expansion. To address this, we randomly selected three N. peltata stands to investigate the seed bank characteristics of N. peltata in Lake Taihu. Results showed that N. peltata had high seed production, with a maxi...

The consumption of oxygen by germinating seeds of Lupinus albus can be reversibly inhibited by CO to a maximum extent of 36 per cent with a mixture of 24 per cent O(2) and 76 per cent CO at 18 degrees , in darkness. This inhibition is completely abolished when the seed is illuminated. On returning to air, after a period in the CO-O(2) mixture, the rate of oxygen consumption is accelerated to as...

Digital pelvic radiographs are used to identify the locations of implanted iodine-125 seeds and their numbers after insertion. However, it is difficult and laborious to visually identify and count all implanted seeds on the pelvic radiographs within a short time. Therefore, our purpose in this research was to develop an automated method for estimation of the number of implanted seeds based on t...

To establish an efficient regeneration system for Anthurium andreanum cv Rubrun, seeds from plant spadixes were germinated on a medium supplemented with 2.2 μ M BA. After 2 weeks, 74% of the seeds germinated and four weeks later, micro-cuttings from these plantlets were subcultured on a medium containing 4.4 μ M BA and 0.05 μ M NAA. On average, 3.6 shoots per explant were obtained. Four weeks o...

The sunflower is considered one of the four most important oilseeds globally. study was conducted on 16 hybrids in field conditions to link photosynthesis parameters with yield components using chlorophyll a fluorescence (ChlF), content, leaf temperature and agronomic traits. By analysing ChlF flowering stage hybrids, statistically significant difference found between studied for all except pho...

This article presents a quantitative analysis of the role played by poly(vinylpyrrolidone) (PVP) in seed-mediated growth of Ag nanocrystals. Starting from Ag nanocubes encased by {100} facets as the seeds, the resultant nanocrystals could take different shapes depending on the concentration of PVP in the solution. If the concentration was above a critical value, the seeds simply grew into large...

MOTIVATION Standard search techniques for DNA repeats start by identifying small matching words, or seeds, that may inhabit larger repeats. Recent innovations in seed structure include spaced seeds and indel seeds which are more sensitive than contiguous seeds. Evaluating seed sensitivity requires (i) specifying a homology model for alignments and (ii) assigning probabilities to those alignment...

In order to investigate the appropriate combination of chemical and bio-fertilizers and their effectiveness on corn seed yield while defoliating the upper leaves of the ear, a randomized complete block design experiment with four replications. Fertilizer treatments were applied at four levels including 100% urea, 75% urea + 100% Nitroxin, 50% urea + 100% Nitroxin, 25% urea + 100% Nitroxin. In h...
