Morphological characters such as main stem length (cm), number of branches per plant, leaf length (cm), number of leaves per main stem, number of leaflets per leaf, diameter of main stem (mm), pods / main stem and seeds / pod as well as agricultural herbage yield (t ha), dry matter yield (t ha), seed yield (t ha), crude protein (%) were investigated in Trakya, during the 1999-2002. The maximum ...

Understanding the distribution of traits across the angiosperm phylogeny helps map the nested hierarchy of features that characterize key nodes. Finding that Amborella is sister to the rest of the angiosperms has raised the question of whether it shares certain key functional trait characteristics, and plastic responses apparently widespread within the angiosperms at large. With this in mind, w...

Let T be a tree. A vertex of T with degree one is called a leaf, and the set of leaves of T is denoted by Leaf(T ). The subtree T − Leaf(T ) of T is called the stem of T and denoted by Stem(T ). A spanning tree with specified stem was first considered in [3]. A tree whose maximum degree at most k is called a k-tree. Similarly, a stem whose maximum degree at most k in it is called a k-stem, and ...

Andrographis alata Nees is an important medicinal plant. The current study was to investigate the antibacterial, antifungal activity and phytochemical analysis of the various leaf and stem extracts of A.alata. Methanol, ethanol, chloroform, acetone and petroleum ether extracts of shade dried plant leaf and stem of A.alata were tested for antibacterial, antifungal and phytochemical screening. Th...

During the development of woody twigs, the growth in leaf may or may not be proportional to the growth in stem. The presence or absence of a synchronicity between these two phenologies may reflect differences in life history adaptive strategies concerning carbon gain. We hypothesized that sun-adapted species are more likely to be less synchronous between growths in total leaf area (TLA) and ste...

Common purslane is a widely distributed summer annual weed. It can vegetatively reproduce from stem cuttings by forming adventitious roots from the cut end of the stem. Apart from large stem cuttings, it is unclear if purslane cuttings of various plant tissues differ in their ability to asexually reproduce. The objective of the study was to determine the survival and asexual reproductive capaci...
