root morphological and distribution responses of signal grass (brachiaria decumbens) to long-term cattle grazing were examined in a tropical pasture in malaysia. the treatments were no grazing by cattle and grazing at a moderate stocking density (2.7 animal unit/ha) under rotational grazing for 33 years. the method consists of taking soil core using a soil corer to a depth of 30 cm and extracti...

the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...

The study was carried out to determine the root architectural characteristics of one-year saplings two species boxwood (Buxus sempervirens L. and Buxus balearica Lam.), which are endangered natural plants Turkey, in greenhouse environment using WinRhizo analysis program scanner. Total length (cm), surface area (cm2), volume (cm3), average diameter (mm), number tips, forks crossings were determi...

In a pot culture experiment, the root length density, potassium concentration in crop, and total K uptake by wheat (Triticum aestivum var. HD 2285) at different growth stages (CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage) were determined. Wheat crop was grown in 72 pots containing 4.5 kg of three types of soils, namely Alfisol,...

Root-knot nematodes cause physiological and anatomical disorders in plants. The present study contains the results of an investigation of the effect of Meloidogyne incognita race2 on the growth of roots and aerial organs of tomato under greenhouse conditions. The experiment in a completely randomized design split split plot on two susceptible (Falat Y) and tolerante (Gina VF) tomatoes variety w...

Specific root length (SRL) and root tissue density (RTD) are ecologically functional traits which are calculated from root length or volume and root dry weight. Both can be converted into each other using the root diameter assuming roots are cylindrical. The calculation of volume from length or length from volume is, however, problematic because samples of roots do usually not have a constant d...

one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...

In order to study the effects of water deficit and foliar application of salicylic acid and spermine on dry matter production and biochemical and morphological treats of Echinacea purpurea, a split plot experiment was conducted based on randomized complete block design with three replicated during 2016- 2017 growing seasons at research field of Institute of Forests and Rangelands, Iran. In this...
