Herbivore-induced plant volatiles have been shown to serve as indirect defence signals that attract natural enemies of herbivores. Parasitoids and predators exploit these plant-provided cues to locate their victims and several herbivores are repelled by the volatiles. Recently, benefits, in terms of plant fitness, from the action of the parasitoids were shown for a few systems. However, the cos...

Inspired by the discussion in most recent neurological research about the role of callosal fiber connections with respect to brain asymmetry [1, 2] we developed a technique that can measure distances between brain hemispheres in a non-Euclidean, curvilinear space. The new technique is a generic morphometric tool for measuring minimal distances within and across 3-D structures, but the project d...

Native seed underpins the success of most terrestrial restoration efforts globally; however, fragility native supply chain presents a key challenge to achieving global goals. With current heightened focus on ecological restoration, chains are under unprecedented pressure worldwide. New and practical solutions required help industry move toward more sustainable reliable supply, in turn, facilita...

Field experiments were conducted to study the effect of organic matrix based slow release fertilizers (SRFs) on plant growth, nitrate assimilation and seed yield of Brassica juncea L. cv, pusa bold. The agro-waste materials like cow dung, clay soil, neem leaves and rice bran were mixed together in 2:2:1:1 ratio and used as organic matrix for the immobilization of chemical fertilizer nutrients w...

In bootstrapping (seed set expansion), selecting good seeds and creating stop lists are two effective ways to reduce semantic drift, but these methods generally need human supervision. In this paper, we propose a graphbased approach to helping editors choose effective seeds and stop list instances, applicable to Pantel and Pennacchiotti’s Espresso bootstrapping algorithm. The idea is to select ...

Camelina sativa (L.) Crantz is an oilseed crop with favorable potentials for biodiesel production, such as the high plant yield, oil content in seed, net energy ratio, and low production cost. This review paper deals present state perspectives of from camelina oil. First, important issues seed pretreatment are reviewed. Emphasis given to different technologies that have been used so far worldwi...

The possible effects of seed priming on mitigating the effects of drought stress on germination and early seedling growth of two rangeland plants were evaluated in a laboratory research during 2015-16 growing season. The research was conducted as a 2×3×3 factorial experiment based on completely randomized design with three replications. The first factor was plant type (Festuca ovina and Bromus ...

This research explores the causes of dealer demand amplification leading to a high volume of seed returns in a typical agribusiness supply chain. Seed production occurs months in advance of grower demand, resulting in a limited supply of specific seeds. To hedge against shortages, dealers inflate orders. If demand materializes, dealers benefit from their inflationary behavior. If it does not, t...
