Chemical Priming with Brassinosteroids to Mitigate Responses of Avocado (Persea americana) Trees to Flooding Stress

Horticulturae, 2022
Priming involves the exposure of plants to a mild stress to increase tolerance to a more intense stress in the future. Chemical priming with brassinosteroids reduces the negative effects of flooding on the physiology and survival of some plant species ...

Chemical trees minimizing energy and Hosoya index [PDF]

, 2008
The energy of a molecular graph is a popular parameter that is defined as the sum of the absolute values of a graph’s eigenvalues. It is well known that the energy is related to the matching polynomial and thus also to the Hosoya index via a certain ...

Trees as Bioindicators of Environmental Pollution and Its Impact on Wood Chemical Composition

BioResources, 2021
Trees provide one of the most versatile biomass resources for many applications, namely wood. The chemical composition of wood determines its properties, being of real significance for its further capitalization, and depending on many factors. In nature,

On the Extremal Trees for Some Bond Incident Degree Indices with a Fixed Number of Segments

Journal of Chemistry, 2022
The Gourava indices and hyper-Gourava indices are introduced by Kulli in 2017. These graph invariants are related to the degree of vertices of a graph G. Let Tn,r be the class of all n−vertex chemical trees with r segments. In this paper, we characterize

Note on the Hyper-Wiener Index [PDF]

Journal of the Serbian Chemical Society, 2003
The hyper-Wiener index WW of a chemical tree T is defined as the sum of the products n1n2, over all pairs u, u of vertices of T, where n1 and n2 are the number of vertices of T, lying on the two sides of the path which connects u and u.

Chemical thinning of peach trees

Comunicata Scientiae, 2022
Peach tree thinning is essential to harvest quality fruits and to keep balanced production for several years. Manual thinning of peach trees demands much work force and increases production costs. Chemical thinning may be an alternative solution, but efficiency depends on doses and species.

Height-diameter allometry of tropical forest trees [PDF]

, 2010
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry.
