Salinity stress effects changed during Aloe vera L. vegetative growth [PDF]

Journal of Stress Physiology & Biochemistry, 2012
Salt stress is a limiting factor of plant growth and yield, and becoming a serious problem in the world so in reason to determine salinity effect on aloe growth experiment was conducted in a greenhouse as a bi-factorial in completely randomized ...

Sampling roots to capture plant and soil functions [PDF]

Functional Ecology, 2017
Summary Roots vary in anatomy, morphology and physiology, both spatially (different parts of the same root system) and temporally (plastic changes, root ageing), suggesting that root trait measurements are strongly affected by root sampling categories.

On analog quantum algorithms for the mixing of Markov chains

, 2020
The problem of sampling from the stationary distribution of a Markov chain finds widespread applications in a variety of fields. The time required for a Markov chain to converge to its stationary distribution is known as the classical mixing time.

The Square Root UKF-SLAM Algorithm Based on the Smallest Proportion of Skewness in Single Line Sampling

MATEC Web of Conferences, 2018
In view of the distortion in the filter gain matrix calculation as well as the high computational complexity and the nonlocal effect of symmetric sampling that exists in the UKF-SLAM algorithm, the square root UKF-SLAM algorithm based on the smallest ...

TEMPORALLY VARIABLE GEOGRAPHICAL DISTANCE EFFECTS CONTRIBUTE TO THE ASSEMBLY OF ROOT-ASSOCIATED FUNGAL COMMUNITIES

Frontiers in Microbiology, 2016
Root-associated fungi are key contributors to ecosystem functioning, however the factors which determine community assembly are still relatively poorly understood.

Pluto: a Monte Carlo simulation tool for hadronic physics [PDF]

, 2008
Pluto is a Monte-Carlo event generator designed for hadronic interactions from Pion production threshold to intermediate energies of a few GeV per nucleon, as well as for studies of heavy ion reactions.

Microbiota dynamics and source tracing during the growing, aging, and decomposing processes of Eucommia ulmoides leaves

Frontiers in Microbiology
Eucommia ulmoides, an important tree, faces serious threat to its growth from environmental stress, particularly climate change. Using plant microbes to enhance host adaptation to respond climate change challenges has been recognized as a viable and ...

Social Roots of Defining Art: Sample of Art Students

Procedia - Social and Behavioral Sciences, 2012
AbstractFor sure, to carry out a debate on the whatness of art is an attempt that should be affirmed. However, to discuss the whatness of art just through the concepts may end up with the ignorance of the most important element for creation of art, human being and its social and artistic position.

Two-dimensional root phenotyping system based on root growth on black filter paper and recirculation micro-irrigation

Czech Journal of Genetics and Plant Breeding, 2016
Plant root system architecture (RSA) has an important role in crop production, particularly for water and nutrient uptake under limiting conditions. In the last few years, several root phenotyping methods have been developed.

Seasonal Fluctuations in Plant-Parasitic Nematode Vertical Distributions and Their Interactions with Edaphic Factors in Vegetable Fields of South Georgia, U.S.A.

Phytobiomes Journal
Plant-parasitic nematodes (PPNs) can be found deep in the soil profile, compounding nematode management decisions and detection. This study aimed to understand how seasonal fluctuations in edaphic factors are associated with the vertical distribution of ...
