“…Plant microbe interactions play a crucial role in many ways [7,8]. Including the promotes nutrient absorption [9,10] and enhancement of plant resistance [11,12]. Plant endophytes refer to a class of microorganisms that live in plant tissues or cell spaces for a long time and do not affect the normal growth of plants [13,14].…”

Screens for Fusarium wilt antagonistic bacteria have generally focused on screening for antagonistic strains from healthy plants, with few reports of screening for antagonists from leaves of diseased plants. In this study, we used cucumber leaves infected with Fusarium wilt disease for the isolation of antagonists and a total of four endophytes with obvious antagonistic effects were screened. Based on the results of physiological and biochemical experiments and 16S rDNA gene sequencing, four strains were identi ed as Paenibacillus polymyxa (Y-4, Y-6, Y-14) and Bacillus Zanthoxylum (Y-9), and all antagonistic strains exhibited the ability to produce amylase, pectinase and hydrogen peroxide (H 2 O 2 ). In pot test, antagonistic bacteria were able to signi cantly reduce the disease index in cucumber seedlings challenged with the pathogen. Four strains of antagonistic bacteria can alleviate the damage caused by Fusarium oxysporum f. sp. cucumerinum (FOC) invasion by increasing the photosynthetic e ciency, antioxidant capacity and root vigor of cucumber seedlings. In conclusion, the leaves of cucumber diseased strain may also be a potential source for screening novel antagonistic agents against cucumber Fusarium wilt. The screened four strains of antagonists had a certain biocontrol potential against FOC and could play a certain role in environmental-friendly agriculture in the future.

“…Gibberellins are growth regulators that have a role in stimulating stem enlargement, flowering and fruit enlargement. Hormone gibberellins in plants affects the process of cell division and cell enlargement [7]. Gibberellins are able to increase auxin levels in plants through the synthesis of proteolytic enzymes that are able to soften cell walls.…”

Melon is an important horticultural commodity in Indonesia because it has high commercial value and broad market target. TEFA SGH Polije has been known as an agribusiness producer of high-quality melons in Jember and it needs to be developed to increase productivity and economic profit. This study aimed to determine the effect of different concentrations of AB Mix and Gibberellins and their interactions on increasing the growth and production of hydroponically cultivated melons. This research was conducted from June to August 2022 at TEFA SGH Polije at 90 msl. This research used Factorial Completely Randomized Design. The first factor was the AB mix concentrations, i.e., 1,400; 1,600; 1,800 and 2,000 ppm. The second factor was the gibberellin concentrations, i.e., 0; 30; 60; 90; 120 and 150 ppm. Each treatment combinations were repeated three times, so there were 72 experimental units. Each experimental unit used 3 plant samples. Observation variables were stem diameter, fruit weight, fruit diameter, fruit flesh thickness, total soluble solids and leaf chlorophyll content. Data were analyzed using analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT). The interaction between AB Mix and gibberellin had significant effects on stem diameter and fruit flesh thickness.
