Effect of biofertilizer on growth and metaxylem diameter of Amaranthus tricolor L. in salinity stress condition

Abstract

Throughout history, agricultural sector in Indonesia has faced a shortage of land. As a result, we must take use of land that is still available, even if the conditions are unsuitable for plant growth, one of which is salinity-stressed land. Amaranth is a frequently cultivated plant in Indonesia (Amaranthus tricolor L.). This vegetable plant is commonly consumed as food due to its nutritional content and numerous health benefits. To cultivate amaranth on salinity-stressed land, additional nutrients are required to ensure that the plants continue to thrive. One of them is the provision of biofertilizers, a type of organic fertilizer that contains beneficial bacteria for plant growth. This study aimed to determinate the effect of biofertilizer application on the growth and diameter of the stem metaxylem of amaranth plants growing in a salinity-stressed environment. As a salinity stress treatment, NaCl was applied at doses of 0, 2500, 5000, 7500, and 10000 ppm. The diameter of the metaxylem was determined by making fresh preparations across amaranth stems. The biofertilizer application does not affect the height and number of leaves of the plant. However, as the dose of biofertilizer was increased, the value of the metaxylem diameter of the stem increased.

Evaluating the Impact of Fertilisers and Elicitors on Amaranthus cruentus (L): Sustainable Fertilization and Elicitation Strategies for Enhanced Nutrition and Productivity

“…Pelinganga [45] also showed that NPK fertilisers improve the chlorophyll content and yield of Amaranthus hybridus. This assertion was corroborated by [46], who observed improved growth and chlorophyll content in Amaranthus tricolor. The elicitors significantly influenced the chlorophyll content of Amaranthus cruentus with the highest chlorophyll content when compared to the control obtained in plants treated with SA250 (Table 2).…”

Liming and Plastering Modify Root Anatomy in Pennisetum purpureum Schum

“…These findings were attributed due to the negative correlation between the Cd content-a toxic element to plants-and the observed changes in diameter. Moreover, salinity and biofertilizers can also modulate the metaxylem diameter of Amaranthus tricolor stem [23].…”

Organic Amendments for Mitigation of Salinity Stress in Plants: A Review

“…The application of BF in wheat seedlings lessened the negative effects of salinity by increasing chlorophyll content and decreasing proline content, and improved plant growth and yield [ 28 , 37 ]. Under salt stress, amaranth enhanced plant height and biomass production [ 101 ]. It has also been reported that the application of BF to lavender enhanced its capacity to withstand salt stress by increasing morphological attributes and RWC, Chl a, Chl b, and total Chl content as well as its essential oil output [ 102 ].…”
