“…A positive correlation was shown by leaf number and N nutrients in leaf, where the higher leaf number, the higher the N nutrients. The N, P and K were often classified as 'primary' macronutrients because deficiencies of these nutrients were more common than the 'secondary' macronutrients (El-Seifi et al, 2015;Singh et al, 2020). Nitrogen was one of the macronutrients that played an essential role in the formation of amino acid, nucleic acid, chlorophyll, proteins, and various secondary and primary metabolites.…”

Winged bean is a remarkable climbing plant, distinguished by its multiple segments that serve as growth sites for shoot, leaf and flower. Several studies have shown that the plant requires shoot pruning to increase the production of its flower buds, pods and seeds, but this practice can inhibit the generative phase. To overcome this challenge, the application of additional fertilizer is needed to provide the required nutrients. Therefore, this study aims to determine the effects of shoot pruning and additional fertilizer on the growth, yield and bioactive compounds of winged bean seeds. The determination of the proper rates of fertilization was important for plant production and to support sustainable agriculture. The study procedures were carried out at IPB experimental station in Leuwikopo, IPB University, Bogor. A Randomized complete block design (RCBD) was utilized with two factors and three replications, namely leaf pruning (without shoot pruning, 15 cm, and 30 cm from the ground) and additional fertilizer (0, 6.25, 12.5 and 18.5 g NPK 16-16-16 plant-1). The parameters observed included plant height, leaf nutrient, root length, yield, leaf number, as well as protein and fatty acid profile of seeds. The results showed that shoot pruning treatment and additional fertilizer had no interaction effect on plant growth and seed yield. Shoot pruning caused an increase in leaf number, fatty acid and linoleic acid content by 17% to 20%, 10%, and 16% to 19%, respectively, compared to the control. The use of additional fertilizer at a concentration of 6.25 to 12.5 g NPK (16-16-16) plant-1 increased leaf number, nutrients, and seed yield. Based on the findings, the highest seed yield (2.56 tons ha-1) was achieved with the application of additional fertilizer at the rates of 6.25 g NPK (16-16-16) plant-1, but shoot pruning was not required.

“…Heavy metals are hazardous inorganic environmental pollutants due to their toxicity. However, when present in low amounts, several heavy metals such as Cu, Fe, Mn, Co, Zn, and Ni are required for plants and animals as micronutrients (Singh et al 2020). Recently, due to high industrial activities and the extensive use of fertilizer and pesticides, heavy metals are present in enormous amounts in the environment, posing a serious global environmental threat.…”

Genotoxic and antigenotoxic potential of encapsulated Enhalus acoroides (L. f.) Royle leaves extract against nickel nitrate

Several environmental pollutants can cause damage to chromosomes, one of which is the heavy metal NiNO3. Some plant extracts have antigenotoxic properties that result in a decrease in chromosomal damage. Member of flowering plants that need to be tested is seagrass. One seagrass species is Enhalus acoroides which was found to contain phytochemical compounds. This study aimed to analyse the genotoxic effect and the potential of encapsulated E. acoroides leaf extract as antigenotoxic against nickel nitrate NiNO3. The extraction was conducted using a mixture of chloroform and ethanol, and crude extract encapsulated using maltodextrin and tween 80. Chromosomal aberrations were evaluated using the squash technique of Allium cepa var. aggregatum root tips. Triphenyltetrazolium chloride and Evans Blue staining were used to observe mitochondrial and apoptotic activities. The results showed that at higher concentrations (250 ppm and 500 ppm), the encapsulated E. acoroides extract decreased mitotic indices; however, no chromosome aberration observed. NiNO3 itself induced a genotoxic effect as observed by low mitotic index and a high percentage of chromosome aberration. The modulation of NiNO3 effect by adding the encapsulated E. acoroides extract at low concentration (100 ppm) increased mitotic index compared to treatment with Ni alone, but did not reduce chromosome aberration. Simultaneous encapsulated E. acoroides extract and Ni treatment, significantly reduced nuclear fragmentation and nuclear lesion. The encapsulated E. acoroides extract can repair several types of nuclear damage but cannot minimise chromosomal damage.
