The overall shape of plants, the space they occupy above and below ground, is determined principally by the number, length, and angle of their lateral branches. The function of these shoot and root branches is to hold leaves and other organs to the sun, and below ground, to provide anchorage and facilitate the uptake of water and nutrients. While in some respects lateral roots and shoots can be...

the purpose of this study is to provide a model for performance evaluation of sepah bank branches by using partial indicators through combining controllable and uncontrollable potential variables with performance variables. with description and expansion of performance concepts of branches, a complete list of pre-test variables, including forty nine potential variables and five performance vari...

An important factor in the growth medium of plants and chemical plants. native substrates can be used to improve plant performance. To evaluate the effect of growth medium on the herb F. benjamina experimental design was completely randomized with eight treatments and four replications were carried out in the research greenhouse of Islamic Azad University of Jiroft. F...

We study the asymptotic properties of a minimal spanning tree formed by n points uniformly distributed in the unit square, where the minimality is amongst all rooted spanning trees with a direction of growth. We show that the number of branches from the root of this tree, the total length of these branches, and the length of the longest branch each converge weakly. This model is related to the ...

We establish convergence to the Kingman coalescent for a class of age-structured population models with time-constant population size. Time is discrete with unit called a year. Offspring numbers in a year may depend on mother's age. 1. Introduction. The well-known coalescent process describes how family lines merge in a sample from a large population, when time is traced backward. It is a conti...

a glasshouse experiment was conducted in universiti putra malaysia (upm) to evaluate the regeneration and yield potential in purslane using both seeds and stem cuttings of 20 collected accessions from different locations in western peninsular malaysia. analysis results revealed significant variations (p< 0.05) for morphological traits viz., plant height, number of main branches, number of nodes...
