Beneficial plant–microbe interaction for enhancing crop yield and quality is a sustainable way to achieve eco-friendly, desirable agricultural productions. The main objective of this experiment was evaluate the individual combined effects an arbuscular mycorrhizal fungus (AMF) strain (Funneliformis mosseae) seaweed extract (SWE) derived from Ascophyllum nodosum, on growth physiological response...

Soybean is an important legume food crop, and its seeds are rich in nutrients, providing humans animals with edible oil protein feed. However, soybean sensitive to water requirements, drought factor limiting yield quality. This study used Heinong 84 (drought resistant variety) Hefeng 46 (intermediate as tested varieties planted chernozem, albic, black soils. The effects of stress on the activit...

An infinite Markov system {f0, f1, . . . } of C2 functions on [a, b] has dense span in C[a, b] if and only if there is an unbounded Bernstein inequality on every subinterval of [a, b]. That is if and only if, for each [α, β] ⊂ [a, b] and γ > 0, we can find g ∈ span{f0, f1, . . . } with ‖g′‖[α,β] > γ‖g‖[a,b]. This is proved under the assumption (f1/f0)′ does not vanish on (a, b). Extension to hi...

M odulated 685-nm chlorophyll fluorescence was measured under steady-state conditions in pea leaves adapted to m oderate actinic light. W hen the m easurem ents were perform ed after a short exposure to heat (42 °C) in darkness, the maximal (Fm) and steady-state (Fs) fluorescence levels were dram atically and irreversibly quenched whereas the basic fluorescence F0 rem ained unchanged. C oncom i...

Opuntia plants grow naturally in areas where temperatures are extreme and highly variable in the day during the entire year. These plants survive through different adaptations to respond to adverse environmental conditions. Despite this capability, it is unknown how CAM photosynthetic activity and growth in Opuntia plantlets is affected by constant heat or cold. Therefore, the main objective of...

As a consistency check of the staggered-fermion fourth-root approximation, we analyze the a0 and f0 correlators, including the effects of two-meson taste-multiplet intermediate states. Rooted staggered chiral perturbation theory describes the contributions from the pseudoscalar taste multiplets in terms of only a few low energy constants, which have all been previously determined by the MILC co...

In this essay, we presuppose basic knowledge of stochastic processes [1]. Let {Xt : t ≥ 0} be a zero mean, unit variance, stationary Gaussian process with twice differentiable correlation function r(|s − t|) = Cov(Xs,Xt). We wish to study the distribution of lengths of intervals between zeroes of Xt. There are two cases: the first in which r(τ) is analytic (implying differentiability up to all ...

{(f1(x), . . . , fm(x)) : x ∈ T } for quadratic polynomials f0, . . . , fm and a subset T of R . This paper studies semidefinite representation of the convex hull conv(V ) or its closure, i.e., describing conv(V ) by projections of spectrahedra (defined by linear matrix inequalities). When T is defined by a single quadratic constraint, we prove that conv(V ) is equal to the first order moment t...
