Low tapping frequency to increase productivity in Thailand [PDF]

, 2019
The purpose of this study was to assess tapping systems to decrease tapping frequency with stimulation in order to increase yield per day and tapper productivity. This experiment was set up in Chachoengsao Rubber Research Center since 2016.

Gene expression analysis for identifying candidate genes for controlling oxidative stress in rubber tree [PDF]

, 2009
Hevea brasiliensis is the main source of natural rubber which is biosynthesized in latex cells. The high metabolic productivity required for latex regeneration after each tapping can be enhanced by ethylene application, which optimizes the production ...

The powdery mildew effector Eae1 targets a SAMS enzyme within the ethylene biosynthesis pathway to disrupt plant immunity

Phytopathology Research
Phytopathogens secrete effector proteins that disrupt plant immunity. Phytohormones, such as ethylene, function as immune signals that regulate plant responses to phytopathogens.

Sucrose versus maltose effect on metabolic pathways in somatic embryogenesis of Hevea brasiliensis [PDF]

, 2004
Somatic embryogenesis in Hevea is stimulated when the embryogenesis induction medium contains maltose, rather than glucose, fructose, or sucrose, in equimolarity (Blanc et al., 1999).

L'encoche sèche chez Hevea brasiliensis [PDF]

, 1994
L'absence totale ou partielle d'écoulement du latex ou encoche sèche d'Hevea brasiliensis peut s'accompagner ou non de nécrose. S'il n'y en a pas, il s'agit le plus souvent d'une fatigue des laticifères et, après une période de repos, l'exploitation peut reprendre.

Investigations on the nutritional status of Hevea brasiliensis plantations in the humid forest zone of CameroonPart 1: Micronutrient status and distribution in soils

Journal für Kulturpflanzen, 2013
Micronutrients are very essential for plant growth. To make statements about the optimum micronutrient supply for Hevea brasiliensis, the micronutrient concentrations of selected soils in Cameroon under Hevea brasiliensis cultivation were studied.

Identification of a differentially expressed thymidine kinase gene related to tapping panel dryness syndrome in the rubber tree (Hevea brasiliensis Muell. Arg.) by random amplified polymorphic DNA screening

International Journal of Plant Biology, 2010
Tapping panel dryness (TPD) syndrome is one of the latex yield affecting factors in the rubber tree (Hevea brasiliensis Mull. Arg.). Therefore, identification of a DNA marker will be highly useful for screening progenies in breeding programs.
