Maclura pomifera, commonly known as the Osage orange (/ ˈ oʊ s eɪ dʒ / OH-sayj), is a small deciduous tree or large shrub, native to the south-central United States.It typically grows about 8 to 15 metres (30–50 ft) tall.
There's a tree in your backyard that produces spiked round balls, and you have no idea what it is. We can help you identify it, and explain the purpose of those odd seed pods it drops.
In computer science, a k-d tree (short for k-dimensional tree) is a space-partitioning data structure for organizing points in a k-dimensional space. K-dimensional is that which concerns exactly k orthogonal axes or a space of any number of dimensions. [1] k-d trees are a useful data structure for several applications, such as:
The sandbox tree's fruits are large, pumpkin-shaped capsules, 3–5 cm (1–2 in) long, 5–8 cm (2–3 in) diameter, with 16 carpels arranged radially. Its seeds are flattened and about 2 cm (3 ⁄ 4 in) diameter. The capsules explode when ripe, splitting into segments and launching seeds at 70 m/s (250 km/h; 160 mph). [5]
On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
After canopy closure, plant growth is not proportional to size anymore, but changes to linear, with in the end saturation to a maximum value when crops mature. Equations used to describe plant size over time are then often expolinear [15] or sigmoidal. [16] [17] Agronomic studies often focus on the above-ground part of plant biomass, and ...
In young plants, growth allocation is often quite similar to the actual biomass allocation. But especially in trees, there may be a high yearly turnover in leaves and fine roots, and a low turnover in stems, branches and thick roots. In those cases, the allocation of growth and the final biomass allocation may diverge quite strongly over the years.
In biology and botany, indeterminate growth is growth that is not terminated, in contrast to determinate growth that stops once a genetically predetermined structure has completely formed. Thus, a plant that grows and produces flowers and fruit until killed by frost or some other external factor is called indeterminate.
