at the crop level, the drought stress accounts for most variations in yield. a controlled glasshouse investigation at day/night temperatures of 22/15°c based at perth city, western australia was performed (in 2006) to assess the influence of different soil moisture contents (field capacity percentage basis) on emergence as well as early plant growth in twenty chickpea genotypes. the experiment ...

Early-successional vegetation is often a major factor that limits recovery of tropical forest in abandoned pastures by outcompeting seedlings of forest trees. The goal of this study was to compare the effects of aboveand below-ground competition of pasture grasses and shrubs on the growth of tree seedlings in abandoned tropical pasture in Costa Rica. Seedlings of Calophyllum brasiliense were pl...

The effect of seed size on germination and early growth of maize plant, was examined within three weeks to determine the best seed size require for planting. The larger size seed produced significant growth compared to medium size and small size. The seedling height, seedling width, and seedling biomass increased in larger size seed. The significant growth observed in larger size seed showed th...

In this report, we present a 3D simulator for the numerical validation of segmentation algorithms for seedling in soil from X-ray or MRI. A 3D simulator of root in elongation is coupled to a simulator of the image acquisition to generate images of simulated seedling associated with a known synthetic ground truth. We detail how acquisition parameters of the seedling and parameters of the imaging...

Shortleaf pine (Pinus echinata) is a fire dependent species that is declining across the southeastern US. Its unique basal crook is an adaptation that protects dormant buds from fire and facilitates prolific sprouting of seedling rootstocks following top-kill. Understanding what influences shortleaf pine sprouting after fire could greatly increase success of natural regeneration efforts. We exa...
