Callus Induction of Dendrobium discolor Through The Thin Cell Layer (TCL) Technique Added with 2,4-Dichlorophenoxyaceticacid

open access: yesJURNAL BIOLOGI TROPIS, 2023
Thin Cell Layer (TCL) is a plant propagation technique using thin explants (1-2 mm) through tissue culture. Callus induction is a crucial step in establishing plant regeneration. The type and concentration of growth regulators influence callus formation.

Moving-bed biofilm reactor combined with three-dimensional electrochemical pretreatment (MBBR–3DE) for 2,4-D herbicide treatment: application for real wastewater, improvement of biodegradability

open access: yesRSC Advances, 2021
2,4-Dichlorophenoxyacetic acid (2,4-D) is a herbicide that is considered as a carcinogenic and highly toxic contaminant, and due to its biological and chemical stability, its degradation is very difficult.

Impact of 2,4-D and fipronil on the tropical midge Chironomus sancticaroli (Diptera: Chironomidae).

open access: yesEcotoxicology and Environmental Safety, 2020
Increased use of pesticides in conventional agriculture implies potential risks to the environment. In aquatic ecosystems, benthic organisms may be exposed to pesticides via contaminated water and sediment, leading to several potential cascading effects ...

Precise measurement of the f(s)/f(d) ratio of fragmentation fractions and of B-s(0) decay branching fractions [PDF]

open access: yes, 2021
The ratio of the B-s(0) and B-0 fragmentation fractions, f(s)/f(d), in proton-proton collisions at the LHC, is obtained as a function of B-meson transverse momentum and collision center-of-mass energy from the combined analysis of different B-decay ...

Rapid metabolism increases the level of 2,4-D resistance at high temperature in common waterhemp (Amaranthus tuberculatus)

open access: yesScientific Reports, 2019
Common waterhemp emerges throughout the crop growing season in the Midwestern United States, and as a result, the seedlings are exposed to a wide range of temperature regimes.

Leptonic decay constants f(K), f(D), and f(Ds) with N-f=2+1+1 twisted-mass lattice QCD [PDF]

open access: yes, 2015
We present a lattice QCD calculation of the pseudoscalar decay constants f(K), f(D) and f(Ds) performed using the gauge configurations produced by the European Twisted Mass Collaboration with N-f = 2 + 1 + 1 dynamical quarks, which include in the sea ...

Effect of 2,4-d, hydric stress and light on indica rice (Oryza sativa) somatic embryogenesis.

open access: yesRevista de Biología Tropical, 2014
With the purpose of increasing the embryogenesis regeneration process in vitroplants obtained from somatic embryos of the indica rice variety CR-5272 (Oryza sativa L.), two independent experiments were performed.

Effect of Florasulam and 2,4-D on Fineleaf Fumitory (Fumaria parviflora Lam.) Infestation in Wheat Crop

open access: yes, 2019
Aims: High infestations of Fumaria parviflora (Fineleaf fumitory) may led to cereal crops yield reduction. The aim of this study is to investigate the effect of mixture of Florasulam and 2,4-D on F. parviflora infestation in a soft wheat crop.

Measurements of the branching fractions of the decays B0s→D∓sK± and B0s→D−sπ+ [PDF]

open access: yes, 2012
The decay mode B0s→D∓sK± allows for one of the theoretically cleanest measurements of the CKM angle γ through the study of time-dependent CP violation. This paper reports a measurement of its branching fraction relative to the Cabibbo-favoured mode B0s→D−

In Vitro Callus Induction from Leaf Explants of Vanda sp Stimulated by 2,4-D

open access: yes, 2017
The addition of growth regulator is one of the critical success factors in in vitro cultures. 2,4-D as a plant regulator in media can stimulate the cell division, enlargement of the explants and promotes the formation and growth of callus. The purpose of
