Germination And Growth

Germination and growth performance of Azadirachta indica seedlings were evaluated in a range of growth media with and without bagasse fly ash as a component. The results revealed that the highest germination of 97 per cent was recorded in seeds sown in bagasse fly ash + sand + farm yard manure 2:1:1 ratio followed by seeds sown in bagasse fly ash + red earth + farm yard manure 2:1:1 ratio (88 per cent). The lowest was recorded in sand medium (78 per cent). Seeds sown in red earth registered highest root length (13.30 cm) and dry matter production (0.93g/5seedling). The results on seedling vigour were reflected a similar trend as for germination. From this experiment, it could be concluded that among the different media evaluated for germination test, bagasse fly ash mixed with sand or red earth along with farm yard manure 2: 1:1 ratio found to the best in terms of germination and initial seedling vigour of Azadirachta indica.

The experiment was implemented by CRD design with three replications and lasted for 40 days, from 5 October until 15 November 2020. Four extract concentrations of D. graveolens 0, 2, 6, and 10% were used. The concentration of 0% was considered as control. The allelopathic effect has been studied on five weed species; Amaranthus retroflexus L., Portulaca oleracea L., Lolium multiflorum Lam., Sorghum halepense L., and Cuscuta campestris Yunck. The research also aimed to determine the effect of Stinkwort extract on the growth of tomato seedlings. All concentrations affected seed germination for all studied weeds. The concentration of 10% was more influential in growth-related indicators compared to other concentrations. The seeds of L. multiflorum and rhizomes of S. halepense were more tolerant to D. graveolens allelochemicals in germination rate than A. retroflexus, P. oleracea, and C. campestris. All concentrations led to a reduction in the weed heights and the wet and dry weights compared with the controls. The effect of the extract with various concentrations was catalytic for the growth of tomato seedlings, as the average height of tomato seedlings was in direct proportion to the concentration.

Osmotic agents used to prevent apple pollen grain germination were studied in vitro by applying 10 μL of solutions to germinating apple pollen on germinating and growth media. Seven concentrations (0%, 0.25%, 0.5%, 1%, 2%, 5% and 10%) of the solution were prepared for each chemical and the characteristics of pH, EC, and osmotic potential were measured. Apple pollen was dispersed onto the media in petri dishes. Micro drops of solution were then applied to marked areas. Dishes were then placed in germination cabinets at 25 °C. Cumulative percentage pollen germination was calculated 4, 8, 12, and 24 h after treatment by microscopic observation. Generally, the cumulative percentage pollen germination decreased asymptotically with increasing chemical concentration. The most effective chemicals for restricting pollen germination and growth were CuSO4 (0.25%), CH3 COOH (0.25%), CaCl2 (10%), K2 S2 O5 (0.25%), Methyl Jasmonate (2%). The effect of these chemicals has also been tested on pistil viability both in vitro and on excised limbs.

Kenaf stems were ground and sieved to yield fine (<2mm), medium (2 to 6 mm) or coarse (6 to 12 mm) grades. These grades were mixed at 25, 50 or 75% volumes in sphagnum peatmoss and then provided standard basal fertilization. Tomato and impatiens shoot fresh weights 4 weeks after transplanting (50 mg N.liter-1 daily liquid feed) were greatest in 25% medium kenaf, being 68 and 89%, respectively, those in peat-lite (ProMix BX). In a further study, medium kenaf was soaked for 3 days in 5000, 10000 or 15000 mg N.liter-1 from 20N-4. 3P-8.6K then mixed at 25% volume in peatmoss. Tomato seedlings transplanted into these media were provided 0, 100, 300 or 500 mg N.liter-1 daily liquid feed (LF) from 20N-4.3P-8.6K. With ≥100 mg N.liter-1 LF, soak solution concentration had no effect on shoot fresh weight. With 0 mg N.liter-1 LF however, kenaf media soaked in 10000 or 15000 mg N.liter-1 yielded greater shoot fresh weights than ProMix with 100 mg N.liter-1, LF.

Rhizosphere Sample

The aims of this research are to apply Senaru forest  rhizosphere on Kabupaten Lombok Barat West Nusa Tenggara as Mycorrhiza inoculants for Gyrinops versteegii germination and growth. Rhizosphere sample was taken from ten sampling spot on Senaru forest between Latitude: 08o18.808’ S – 08o19.174’ S and Longitude: 116o24.138’ E – 116o24.181’E. This study employed Factorial Experiment Design with 2 Factor including: Medium Composition (M) and Mychorizza Inoculant (I). There were 5 media composition: M1 (sand), M2 (soil:sand = 1:2), M3 (soil:sand = 1:1), M4 (soil:sand = 2:1), M5 (soil). There were 2 types of Inoculation: I1 (without inoculant) and I2 (innoculant from senaru Rhizosphere). Growth parameters observed in this study were: germination percentage, stem length, stem diameter and root colonization. Germination percentage of G. versteegii seeds in all growth media are below 60 % which could be classified as low germination rate. Also germination from media without rhizosphere is higher than germination from media with rhizosphere. On the other hand, G. versteegii growth on rhizosphere media is slightly higher than growth of G. versteegii on media without rhizosphere based on stem diameter and length measurement. It tends that medium composition with higher sand proportion tended to gives better germination and growth rate of G. verteegii. Myorrhiza colonization on G. versteegii root was higher in media with rhizosphere addition. It could be concluded that Application of Senaru rhizosphere containing Mycorrhiza increases G. versteegii growth but not its germination percentage. This research enrich knowledge in biological science about asociation of mycorrhiza with G. versteegii especially on its growth and germination

La capacidad para solubilizar fosfatos y producir compuestos indólicos del tipo Ácido Indol Acético, se evaluó en 15 cepas aisladas de residuos lignocelulósicos de higuerilla (Ricinus communis). Para determinar la actividad solubilizadora de fosfatos se realizó una prueba cualitativa utilizando medio de cultivo Pikovskaya y para evaluar la producción de compuestos indólicos (AIA) se empleó la técnica colorimétrica de Salkowsky. Entre los microorganismos evaluados, Bacillus pumilus GIBI 206 mostró tener la capacidad para solubilizar fosfatos y Bacillus subtilis GIBI 200 evidenció capacidad para solubilizar fosfatos y producir Ácido Indolacético (AIA). Para determinar el efecto de la cepa Bacillus subtilis sobre la germinación y promoción de crecimiento, se inoculó en semillas de tomate (Solanum lycopersicum cultivar Santa Clara); la inoculación de las semillas con el microorganismono mostró diferencias estadísticamente significativas en el tiempo de germinación en comparación con el tratamiento control, sin embargo mostró influir positivamente en el desarrollo de las plantas de tomate  generando un aumento significativo sobre la masa y longitud del tallo y de la raíz. Los resultados de esta investigación ofrecen la posibilidad de utilizar a Bacillus subtilis como promotora de crecimiento en plántulas de tomate y en la formulación de bioinsumos
