Mepiquat natural formation in cocoa commercial products

, 2022
Mepiquat (MQ) is well-known products commonly used in agriculture as inhibitor of gibberellin biosynthesis. Several studies reported the natural formation of MQ in food heated under dry conditions. In this study cocoa products were analysed with IC-HQOMS to evaluate the presence of MQ.

Modelling the structural response of cotton plants to mepiquat chloride and population density [PDF]

Annals of Botany, 2014
Cotton (Gossypium hirsutum) has indeterminate growth. The growth regulator mepiquat chloride (MC) is used worldwide to restrict vegetative growth and promote boll formation and yield. The effects of MC are modulated by complex interactions with growing conditions (nutrients, weather) and plant population density, and as a result the effects on plant ...

Hyperspectral reflectance‐based partial least squares regression models for predicting cotton leaf physiological traits

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Alterations in the mechanistic drivers of photosynthesis have the potential to improve crop productivity, but their measurement is inherently time‐consuming using traditional methods. High‐throughput approaches to estimate photosynthesis using hyperspectral reflectance could be developed by leveraging variation in cotton (Gossypium hirsutum L.)

Nitrogen rate optimization for irrigated cotton in Florida

Agronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract For irrigated cotton (Gossypium hirsutum L.) in Florida, the current nitrogen (N) fertilizer recommendation is 67 kg N ha−1 and has not changed in the last 40 years despite changes in cultural practices and development of new varieties. A study was conducted at three locations to re‐evaluate cotton [Delta Pine 2038 B3XF (DP 2038)] response to ...
