Leaf-area (LA) is a plant-biometric index important to agro-forestry and crop production. Previous works have demonstrated the conservativeness of the inverse of the product of the fresh leaf’s density and thickness the so-called ‘Hughes’ constant’ (K). We use this fact to develop ‘LAMM’, an absolute method of LA measurement (i.e. no regression fits or prior calibrations with planimeters). Nor ...

Abstract Due to climate change, many impacts occur on the sustainability of organisms, including trigona bee. The occurrence change not only affects decreasing honey production but also reduces number colonies. Presume that it can activity pattern This study aims determine demonstrated by Tetragonula laeviceps (Smith) colony in KHDTK Gunung Bromo UNS. research was conducted July 2021 at observa...

Abstract Nitrogen dioxide (NO 2 ) is a significant pollutant in both outdoor and indoor environments with exposure linked to serious respiratory illnesses, decreased lung function airway inflammation. Here, we investigate whether potted plants can contribute as simple cost-effective air pollution mitigation technique. Our study investigates the ability of combination three plant species Spathip...

Fluorescence imaging represents a non-invasive tool for revealing and understanding spatial heterogeneity in leaf performance caused by external factors, such as abiotic stress. Sun (Rosa meillandina and Chrysanthemum morifolium) and shade (Spathiphyllum wallisii) plants were used to study their tolerance to heat and high illumination. Fluorescence yield, effective PSII quantum yield and non-ph...

In order to evaluate the different growing media and nitrogen fertilizer (urea) on some morphological traits of Spathiphyllum plant, an experiment was carried out in split plot arrangement based on completely randomized design in three replications in greenhouse conditions in 2018. The main plot consisted of different growing media including T1: Leaf-mold, T2: Vermicompost and T3: A mi...
