Impact of potassium nutrition on vegetative growth, macronutrient content, and photosynthetic performance in seven cacao (Theobroma cacao L.) cultivars

Technology in Horticulture

Carmona-Rojas, et al.

2025-10-10

Limited progress has been made in developing potassium-efficient cultivars for agriculturally important crops due to a lack of knowledge about the biological mechanisms in tolerant cultivars. For Theobroma cacao L. (cacao) cultivars, the characterization of potassium use efficiency (KUE) has remained largely unexplored. This study aimed to characterize the effects of potassium (K) levels on cacao morphology, biomass production, macronutrient (K, N, Mg, and Ca) accumulation, and photosynthetic performance during the vegetative growth phase.

Storage of embryos and in vitro development of embryonic axes in avocado

Agricultural Research in the Tropics

Gutiérrez-Rodriguez, et al.

2025-03-10

The in vitro establishment of Persea americana embryonic axes is critical for micropropagation and biotechnological applications, particularly following seed storage. This study aimed to evaluate the effects of seed storage duration and culture media composition on the in vitro development of P. americana (‘Toro Canyon’ and ‘Duke 7’ cultivars) embryonic axes in MS (Murashige & Skoog 1962), MSm (30 % of macronutrient reduction) or SHm (modified from Schenk & Hildebrandt 1972) media.

Nutrition in cacao (Theobroma cacao L.) crops: What determining factors should be considered?

Journal of the Agronomy College

Rojas, et al.

2022-11-29

Cacao (Theobroma cacao L.) is an important commercial crop and agricultural commodity worldwide; for some Latin American countries, it is an essential part of export products. In Colombia, this crop has promising conditions to extend and strengthen this agriculture sector. However, their productivity is low under current agricultural practices, mainly due to insufficient modernization and inadequate or no management of their nutritional schemes. This publication reviewed the different findings currently in the scientific literature regarding the factors that determine the nutritional status of cacao plants, such as the function and distribution of minerals, nutritional efficiency, soil properties, establishment systems, organic and organic and inorganic sources examined.
