Endophytic and plant-associated bacteria were isolated from plants and rhizoplane soil of naturally grown Brachiaria grasses at International Livestock Research Institute in Nairobi, Kenya. Eighty-four bacterial strains were isolated from leaf tissues, root tissues, and rhizoplane soil on nutrient agar and 869 media. All bacterial strains were identified to the lowest possible taxonomic unit us...

to study the effect of salinity on physiological and morphological traits of chickpea in 2010 at faculty of agriculture and natural resources, university of tehran with seven chickpea genotypes. two experiments design was rcbd with 3 replications and 5 levels of salinity stress (ctrl, 200, 150, 100, 50 mm) for laboratory experiment on germination indices and greenhouse experiment on physiologic...

A field experiment was conducted using a 3 × 3 orthogonal regression design to explore the growth promotion of one-year-old Yunnan pine seedlings (Pinus yunnanensis Franch.) in response to foliar application of IAA (indole-3-acetic acid) at rates of 0, 200 and 400 mg·L(-1) and IBA (indole-3-butyric acid) at rates of 0, 200 and 400 mg·L(-1) in order to promote the growth during the seedlings' ea...

Abstract: Both protein and starch hydrolysis contribute to the effective mobilization of seed reserves trigger germination. We studied activities hydrolytic enzymes in germinating seeds mung bean (Vigna radiata) exposed cadmium stress at 0, 25, 50, 75, 100 mg.L-1. Exposure Cd decreased germination rate early seedling growth traits, including root shoot length plant fresh dry biomass compared co...

Aim of study: We aimed to i) evaluate the effects mulching on Tuber melanosporum mycelium biomass and seedling growth (i.e. root collar diameter height) ii) unravel relationship between in abundance, a T. plantation.Area The experimental plantation is located Pre-Pyrenees mountains Catalonia, Spain.Material methods: was established 2010 using one-year-old inoculated Quercus ilex seedlings. Doub...

The objective of this study is to understand the response of Quercus suber seedlings to light and water, two limiting factors of their growth and survival in Mediterranean woody plants. Greenhouse and field experiments were conducted to contrast the results from both types of experiments. At the greenhouse experiment, Quercus suber seedlings were grown at three treatments of light (3%, 27% and ...

Fire and the invasive annual grass Microstegium vimineum in eastern deciduous forests" (2012). Abstract Non-native plant invasions have the potential to change natural and prescribed fire regimes by increasing fuel loads, continuity of fuels, and fuel composition, which may alter fire intensity, damage native species, and promote further invasions. In this project we sought to evaluate the inte...

1. Ambrosia trifida L. (giant ragweed), an aggressive weed of US grain crops and indigenous to North America, colonizes no-tillage crop fields and undisturbed soils despite its large seed size and susceptibility to seed predation. Secondary seed dispersal is critical to seed survival and seedling establishment, yet mechanisms of secondary dispersal are poorly understood for such large-seeded we...

Potted-seedling machine transplantation (PSMT) is an innovative method of mechanical rice transplanting to improve seedling quality and reduce injury relative blanket-seedling (BSMT). However, the responses yield, grain quality, risk lodging in PSMT have not yet been comprehensively defined. Here, we present a meta-analysis 67 peer-reviewed studies with 382 field observations investigate impact...

Understanding the complex mechanisms controlling treeline advance or retreat in the arctic and subarctic has important implications for projecting ecosystem response to changes in climate. Changes in landcover due to a treeline biome shift would alter climate feedbacks (carbon storage and energy exchange), ecosystem services such as wildlife and berry habitat, and landscape flammability. Wildfi...
