“…strain EK ameliorated the growth of tomatoes in acid sulfate soil. A strain of B. silvatlantica has been proven as an endophyte of pineapples (da Silva et al, 2020). Bacterial endophytes are known to be capable of enhancing the growth and development of plants (Santoyo et al, 2016).…”

Acid sulfate soils are limiting the productivity of pineapples (Ananas comosus (L.) Merr. var. comosus) by lacking available P content. This study aims to evaluate the potency of P-solubilizing bacterial endophytes, Burkholderia silvatlantica L-VT09 and N-VT06, on acid sulfate soil properties and features of pineapples grown in that soil. The two-factor experiment was arranged according to a completely randomized block design. One factor was P fertilizer levels: 25% P, 50% P, 75% P, and 100% P; the other was supplementations of P-solubilizing bacterial endophytes: No supplementations, individual supplementation of L-VT09, individual supplementation of N-VT06, and mixed supplementation of both L-VT09 and N-VT06. The result revealed that supplying the mixture of B. silvatlantica L-VT09 and N-VT06 did improve the soil fertility as increasing available P content and bacterial density (12.6 mg P kg -1 and 3.82 most probable number g -1 dry soil weight, respectively), P uptake (19.2 kg ha -1 ), growth as boosting plant height (8.30 cm), leaves number per plant (6.60 leaves plant -1 ), D-leaf length and width (2.80 and 0.32 cm, correspondingly), stem size (3.40 cm in length and 0.44 cm in diameter), yield components as enhancing fruit length and fruit diameter (3.50 and 1.46 cm, sequentially), yield (11.5 t ha -1 ), and pineapple fruit quality as ameliorating sugar content (1.71 °Brix) and water content (166.4 mL), in comparison with the no bacteria supplied case. Supplying the mixture of B. silvatlantica L-VT09 and N-VT06 altered 75% P but still maintained pineapple yield.

“…In this experiment, the number of leaves, plant height, stem thickness, leaf area, dry matter accumulation in each organ, G value, and SI of tomato seedlings increased and then decreased with the increased concentration of Bacillus methylotrophicus. That is, the growth effect of Bacillus methylotrophicus on tomato seedlings also showed growth inhibition at high doses and growth promotion at low doses.PGPR can promote plant growth and development directly or indirectly by fixing nitrogen, mineralizing elements, changing the soil microorganism group, improving soil physical and chemical properties, enhancing soil fertility, secreting phytohormones, and secreting related regulatory substances[42][43][44] (Souza et al, 2015; Compant et al, 2019; Da Silva et al, 2020…”

Effect of Bacillus methylotrophicus on Tomato Plug Seedling

Tomato production is gradually shifting to modern production, which requires the factorization of tomato seedlings to shorten the seedling cycle and improve the seedling quality. Bacillus methylotrophicus, as a biofertilizer for plant growth-promoting rhizobacteria, can promote plant growth and enhance native plant defenses. However, reports on the role of this type of bacterial agent in horticultural crop seedlings are limited. We investigated the effects of different dosages of Bacillus methylotrophicus (0.00, 0.25, 0.50, 0.75, 1.00, 1.25, and 1.50 g/strain) on tomato plug seedlings and aimed to screen out the suitable dosage of Bacillus methylotrophicus for tomato seedlings in 50-hole cavity trays. In this experiment, with the increase in Bacillus methylotrophicus, the number of leaves, plant height, stem thickness, leaf area, dry matter accumulation in each organ, growth function (G value), and seedling strength index of tomato seedlings showed an increasing trend, followed by a decreasing one. The appropriate dosage (0.50–1.25 g/strain) of bacterial agent increased the activities of the substrates urease, sucrase, and catalase, thus forming a good microbial community to maintain the balance of organic and inorganic carbon and guaranteeing the normal development of the root system. Meanwhile, under the treatment of 1.00 and 1.25 g/strain of inoculum, the absorption range of tomato roots increased, more nitrogen, phosphorus, and potassium were absorbed from the substrate, and more nutrients were transported from the underground to the above-ground parts, which promoted shoot elongation and thickening of the shoots, increased the leaf number and dry matter accumulation, and improved the seedling quality. In this study, the mechanism of action of this microbial product on tomato seedlings was studied from the perspective of nutrient uptake and supply, and a sowing root application of 1.00 g/strain of Bacillus methylotrophicus in 50-hole cavity trays can improve the quality of tomato seedlings.
