“…The role of ethylene in the ripening process of oil palm fruit is related to the expression of the EgERD3 gene in mesocarp tissue, where the expression of this gene follows the ripening pattern of oil palm fruit. The EgERD3 gene plays a role in ethylene synthesis and signaling pathways in the mesocarp (Nurniwalis et al, 2018). It is known that 1-MCP is an anti-ethylene agent which works by blocking ligand receptors.…”

Soil acidity is one of the main factors limiting the growth and sustainable production of oil palm in Indonesia. The aim of this study was to evaluate the effect of various exogenous compounds on improving fruit growth and oil yield of palm oil grown on Ultisol. The experiment employed three treatments which were arranged in a Randomized Complete Block Design (RCBD) with three replications. The treatments were: 1-MCP (0, 100, 200, and 300 ppm), CaCl2 (0 and 50 ppm) and NAA (0 and 200 ppm). Application of Ca2+, NAA and 1-MCP either single or in combination improved fruit growth and oil yield by increasing almost all variables, except the number of bunches, bunch weight and fruit set. The 100 ppm 1-MCP + 50 ppm Ca2+ + 200 ppm NAA treatments showed the highest oil-to-dry mesocarp content. To get the highest oil to bunch (OB), the combination of 100 ppm 1-MCP + 200 ppm NAA; 50 ppm Ca2+ + 200 ppm NAA, and a single treatment of 50 ppm Ca2+ were very promising to be utilized.

“…One example, ethylene has been applied in date fruits (Phoenix dactylifera L.) to increase ripening rate and facilitate early harvesting [15,16]. Indeed, the application of ethephon is not new to oil palm FFB, but it is only limited to accelerate fruit abscission to increase oil extraction rate in oil mills [17][18][19][20]. However, the applicability of ethephon/ethylene to increase the efficiency of oil palm seed production has yet to be reported.…”

Oil palm seed producers typically require 10 months of various processes from pollination to seed germination to produce commercial dura × pisifera hybrid seeds. Conventional forced fruit shedding from underripe fresh fruit bunches (FFB) usually causes seed damage and an extended retting period (incubation for natural fruit abscission from spikelets), eventually leading to bunch rot and disease infection. As a fruit ripening agent, ethephon has been explored to hasten fruit abscission in many fruit crops and oil palm. Nevertheless, the previous studies in oil palm only focused on fruit shedding from FFB to improve oil extraction rate in oil mills without considering the actual FFB ripeness and retting period, which are critical for oil palm seed production. In this study, the application of ethephon containing buffer (adjusted to pH 9.0) to underripe FFB at 145 days after pollination (DAP), 135 DAP and 125 DAP resulted in 50% more fruit abscission after a 72-h incubation. Considering the minimal seed loss upon FFB harvest (<1%) and 50% reduction in retting period, underripe FFB at around 145 DAP was found to be optimum for seed production using ethephon treatment. The treatment, however, made negligible improvement in fruit detachment for ripe FFB at 150 DAP and older. Importantly, seed germination and culling rate at nursery stages were not significantly affected by the ethephon treatment. Hence, ethephon application can improve commercial seed production practices for oil palm.
