On structural properties of ABC-minimal chemical trees
Applied Mathematics and Computation, 2019 The atom-bond connectivity (ABC) index of a connected graph G is defined as A B C ( G ) = ∑ u v ∈ E ( G ) d ( u ) + d ( v ) − 2 d ( u ) d ( v ) , where d(w) is the degree of vertex w in G and E(G) is the set of edges of G. Given greedy trees perturbed by

Chemical defoliation of fruit trees
California Agriculture, 1977 Trees in most mature peach, nectarine, and plum orchards in the southern San Joaquin Valley cease growth by early to mid-October. Because the foliage often persists on the trees for another three to five weeks and interferes with the pruner's vision, it ...

Chemical “pruning” of walnut trees
California Agriculture, 1980 A chemical pinching agent sprayed on young walnut trees in the spring reduced terminal growth and increased branching, producing a response similar to that obtained by pruning.

International Journal of Quantum Chemistry, 1982 AbstractA method is developed for obtaining the spectra of trees of NMR and chemical interests. The characteristic polynomials of branched trees can be obtained in terms of the characteristic polynomials of unbranched trees and branches by pruning the tree at the joints.
