Background: The aim of this study was to examine the resource allocation among the organs and the leaf morphology of Polygonatum humile. The data were collected from June 2014 to May 2015 in a natural P. humile stand of a temperate forest gap. Results: The dry weight of new rhizome (R0) sharply decreased to the time of new shoot sprouting in next year and was constant for 2 ~ 3 years. However, ...

Callus cultures from stem of O. sanctum were induced on slightly modified Murashige and Skoog's (MS) medium and supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D, 1-2 ppm) and kinetin (kn, 1 ppm). Different extractives of stem, leaf and stem callus of O. sanctum were tested for anticonvulsant activity against standard drug phenytoin using maximal electroshock (MES) model. Ethanol and chlo...

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...

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 ...

Coconut milk was prepared by grinding coconut with water and straining through muslin cloth. To improve total solids and protein contents of coconut milk, various temperatures and pH levels of extraction water were investigated. Coconut milk prepared by grinding coconut with hot water (80C) at pH 8 contained highest solids and proteins. The coconut milk was then blended with various percentages...

twenty-two bread wheat cultivars along with susceptible (sholeh) and resistant (azadi) control cultivars were evaluated for resistance to russian wheat aphid of two growth stages including seedling and stem elongation in greenhouse. five adult aphids per plant were used for infestation. leaf chlorosis at seedling and stem elongation stages and leaf rolling at seedling stage were measured. other...

1. Small stems with one large leaf in the middle produce shoots and roots chiefly at the expense of material sent into the stem by the leaf. Since the sap of the leaf can cause the formation of roots and shoots in the same notch of the leaf, it is difficult to assume that the polar character of the regeneration in the stem is due to a chemical difference in the ascending and descending sap sent...

In order to study the effect of organic fertilizer on shoot yield and essential oil content of lavender, this experiment was conducted in the Research Institute of Forest and Rangelands, Karaj, Iran, in 2013-14. The treatment groups consisted of vermicompost (0, 5, 10 and 15 ton/ha) and cow manure (0, 10, 20 and 30 ton/ha). The experimental design was a factorial experiment based on randomized ...

It?s definitely not a nutty idea to ask more about this oil! Unfortunately, though, the evidence on whether or not coconut oil is healthy is resoundingly? inconclusive. Despite its growing popularity (which may stem from excitement about its perceived health benefits), there is a lack of evidence to support a number of current health claims made about coconut oil (more on those in a bit). While...
