The optimization of crop response to climatic stress through modulation of plant stress response mechanisms. Opportunities for biostimulants and plant hormones to meet climate challenges.

open access: yesNew Phytologist, Volume 249, Issue 1, Page 130-151, January 2026.
Summary This review discusses the use of agronomic management practices to enhance crop stress resilience to climate stress through the modulation of natural plant growth regulatory pathways. The use of biostimulants or plant hormones to improve crop resilience is subject to strict regulatory oversight if changes in the regulation of plant growth are ...

Chlormequat and Aldicarb Reduce Whitefly Infestation on Poinsettia1

open access: yesHortScience, 1975
Abstract Increasing levels of the systemic insecticide 2-methyl-2-(methylthio)propionaldehyde O -(methylcarbamoy)oxime (aldicarb) and a plant growth retardant (2-chloroethyl)trimethylammonium chloride (chlormequat) reduced the mean population of whitefly on poinsettia (

Effect of chlormequat chloride, ß-naphthoxyacetic acid and ethephon on early and total yield of tomato in open field

open access: yesActa Agrobotanica, 2013
Tomato seedlings in hotbed with Antywylegacz (chlormequat chloride) to suppress their excessive elongation before transplanting, were used. Their first 2-3 flower clusters were dipped in the field in Betokson (ß-naphthoxyacetic acid) to induce better ...

A Novel ZjbZIP33‐ZjPRX1 Module Positively Regulates Lignin Formation in the Jujube Fruit Stone

open access: yesPlant Biotechnology Journal, Volume 23, Issue 11, Page 4998-5012, November 2025.
ABSTRACT Fruit stones play an important role in fruit development and are closely related to fruit quality. Lignification of the fruit stone (endocarp) is a typical feature of stone fruits. Stoneless jujube is a valuable jujube germplasm resource, and the degree of lignification of its fruit stone is low.
