Measuring Instant Light-Response Curve of Chlorophyll Fluorescence in Sago Palm (Metroxylon sagu Rottb.) Leaves: Different Time Measurements on Dark and Light-Adapted Leaf
This study aimed to determine the appropriate time for the chlorophyll fluorescence light curve measurement in sago palms and to avoid high values variations. The photosynthetic status of three-year-old sago palm seedlings was evaluated through the chlorophyll fluorescence measurement. The…

Waterlogging and restricted-below ground aeration on photosynthetic performance and root elongation rate of RRIM 600 and RRIT 251 rubber genotypes (Hevea brasiliensis Mull. Arg.)
Due to extended inundation, waterlogging and restricted below-ground aeration cause inhibition in plant growth performance. This study examined two different rubber clones, RRIM 600 and RRIT 251, for waterlogging and restricted below ground aeration. To evaluate the plant performance under the…

Waterlogged Conditions Influence the Nitrogen, Phosphorus, Potassium, and Sugar Distribution in Sago Palm (Metroxylon sagu Rottb.) at Seedling Stages
Sago palm (Metroxylon sagu Rottb.) grows in well-drained mineral soil and in peatland with high groundwater levels until complete submersion. However, the published information on nutrient uptake and carbohydrate content in sago palms growing under waterlogging remains unreported. This experiment…

Ambient air temperatures and solar radiation affect OJIP fluorescence transients of coffee plants in an agroforestry system
Abstract Physiological response of coffee plants to their environment was observed through leaf photosynthetic measurement. The leaf photosynthetic efficiency of coffee plants grown in agroforestry was identified at different elevations. Each elevation has variations in ambient air temperatures…

The impact of different soil water levels on nitrogen, phosphorus, and potassium uptake, photosynthetic performance, and sugar distribution of sago palm seedlings
Abstract Under high soil water levels, an imbalance occurs in the utilization of photosynthate between supporting vegetative growth and storage as starch. This results in a reduction in the density of dry matter in the stem and increased plant size. On the other hand, biomass yield and starch yield…

Sago palm (Metroxylon sagu Rottb.) response to drought condition in terms of leaf gas exchange and chlorophyll a fluorescence
Sago palm (Metroxylon sagu Rottb.) photosynthetic performance was evaluated under drought conditions through leaf gas exchange and chlorophyll a fluorescence measurement. Drought has an impact on sago palm’s leaf gas exchange parameters and its chlorophyll fluorescence of PSII. Stomatal limitations…

Colonization of arbuscular mycorrhizal fungi (AMF) in the rhizosphere of robusta coffee plant (Coffea canephora)
In this study arbuscular mycorrhizal fungi (AMF) colonization in the soil at the Bangelan Robusta coffee plantation, Malang, East Java was observed in two different locations with different plant ages, 49 and 10-year-old. The soil and root samples were collected from 0-50 cm and >100 cm from the…

Investigation on morphological, photosynthetic traits, and arbuscular mycorrhizal fungi (AMF) roots infection in sago palm (Metroxylon sagu rottb.) under saline condition
This study investigated the response of sago palms to saline conditions, focusing on their morphological and photosynthetic performance. The photosynthetic traits were evaluated using OJIP chlorophyll fluorescence transient. The plants were exposed to a saline condition of 224 mM NaCl, and their…

Observation of microclimate diurnal change and successful rate of robusta coffee (Coffea canephora) flower-to-fruit formation
Observation of diurnal change of microclimate conditions in a robusta coffee plantation in Malang, East Java, Indonesia, was conducted from September to November 2023. The observation was done in two different blocks, Block 1 and Block 2 with 35 years and 89 years plants, respectively. The diurnal…
