Opis:
Nowadays, the use of natural polysaccharides in the field of agriculture has increased in order to achieve sufficient yields and quality. Minimal research on effect of biopolymers on growth ornamental plants has been published. Verbena bonariensis L. is a valuable perennial species, recommended for cultivation in gardens and green areas, as well as cut and pot plant. The main objective of the investigation was to analyzed the effects of three polysaccharides on the growth and flowering of V. bonariensis. The plants were sprayed with aqueous solution of chitosan, gellan gum or kappa-carrageenan at a concentration of 0.2%, five times. Control plants were treated with water. The results indicated that polysaccharides significantly enhanced the plant height, number of inflorescences and number of leaves of V. bonariensis plants. Application of chitosan and gellan gum significantly increased the stomatal conductance by 13.8 and 16.3 % and enhanced the number of shoots per plant by 29.4 and 37.5 % compared with that control, respectively. Among the three polysaccharides, gellan gum proved best and gave significantly maximum fresh weight of aboveground part and fresh weight of root by 34.3 and 114 % over the control one.

Opis:
Leucocoryne coquimbensis F.Phil. ex Phil. is an attractive bulb plant which naturally occurs in Chile. It has ornamental blue or violet fragrant flowers. No information has been available on the use of plant growth retardants in the cultivation of L. coquimbensis as potted plant. The objectives of this study were to determine the effect of flurprimidol on plant growth and flowering of L. coquimbensis grown in pots in the greenhouse. In summary, it can be concluded that L. coquimbensis can be cultivated as an attractive pot plant. The use of flurprimidol modifies the appearance of L. coquimbensis, the flowering time and the quality of flowers. We recommend for producing potted plants the application of Topflor 0.1% as foliar spray when the plants was 3 cm tall.

Opis:
The present report illustrates an improved and reproducible micropropagation system for economically valuable bamboo species Pseudoxytenanthera stocksii using nodal segments. Direct organogenesis from nodal segments was accomplished by culturing on Murashige and Skoog (MS) medium supplemented with 6.0 mg/L 6-benzylaminopurine (BAP). On this medium combination 9.0±0.25 shoots per explant were induced. Shoot multiplication was subjective to the combination of auxins and cytokinins concentrations used and number of repeated transfer of mother explants or subculturing of in vitro regenerated shoot clumps on fresh medium. Maximum 41.9±1.00 shoots were observed on MS medium supplemented with 4.0 mg/L of BAP and 0.25 mg/L of naphthalene acetic acid (NAA). Half strength MS medium containing various concentrations of auxins was used for in vitro root formation. Successful rooting with maximum response was achieved on half strength MS medium + 50% sucrose and 1.0 mg/L IBA (24.3±0.27 roots). The rooted plantlets were planted the soilrite and hardened in the greenhouse for 6-8 weeks. Completely acclimatized plantlets exhibited 96% survivability. The present propagation protocol could satisfy the demand of P. stocksii and could be explored for the commercial propagation of this valuable manga bamboo.

Opis:
Tomato and pepper are some of the most important and widely grown vegetable crops in the world. Like many other vegetables and fruits, tomato and pepper are threatened by biotic and abiotic stresses. Conventional agricultural practices frequently rely on synthetic fertilizers and pesticides that have adverse effects on humans, animals and environments. In this situation, the use of Plant Growth Promoting Rhizobacteria (PGPR) can better crop yield, as these are vital components of soil fertility and plant growth promotion, moreover, they can display antagonistic effects against phytopathogens. Under such circumstances, knowledge about the local bacterial populations, their identification, and their implications for improving management practices (vis-a-vis plant growth promotion and destruction of plant diseases) is very important. Recent advances in microbial and molecular techniques have significantly contributed to introducing many different bacterial genera into soils, onto seeds, roots, tubers or other planting materials to control disease and improve productivity. Plant growth promoting rhizobacteria have been generally applied to high value crops like tomato and pepper. Thus, this review is intended to summaries the literature on plant growth promoting rhizobacteria for growth promotion potential and biocontrol agent against tomato and pepper disease.

Chromium is a heavy metal; this element is considered as an environmental hazard. Toxicity effects of chromium on growth and development of plants including inhibition of germination process decrease of growth and biomass of plant. The aim of this research is to study accumulation of Chromium along with nutrients and its effect on the growth of Paddy plant (Oryza sativa L). Thus, paddy seedlings grown in petriplates lined with filter paper undergoing, different treatments of Cr (0, 2.5, 5, 10, 25, 50, 75, 100 and 200 mg/L). After one week seedlings were removed and morpho physiological parameters like root length, shoot length and dry weight of plants and Biochemicals ,accumulation of nutrients along with Cr in roots and shoots were determined. The results indicated that the concentrations more than 100 mg/L chromium cause the reduction of morphophysiology parameters in the treatment plants rather than control plant and Cr addition in the cultures caused enhancement of chromium content in roots and shoots of plant seedlings. Similarly the biochemicals and nutrient accumulation also affected by increasing concentrations of chromium. It was also noted that accumulation of chromium in the roots was much higher than the shoots of the seedlings under treatment.

Opis:
Green revolution increased the food production enormously to feed the geometrically growing population. In India, the availability and affordability of fossil fuel based chemical fertilizers at the farm level have been ensured only through imports and subsidies. Dependence on chemical fertilizers for future agricultural growth would mean further loss in soil quality. The possibilities of water contamination and unsustainable burden of the fiscal system. The Government of India has been trying to promote an improved practice involving use of biofertilizers along with fertilizers. These inputs have multiple beneficial impacts on the soil and can be relatively cheap and convenient for use. The agricultural chemicals like pesticide and weedicides were being used to save the standing crop from the attack of pests and to boost crop production. At the same time the excess use of chemical fertilizers degraded the soil properties. In this context, the farmers are expecting for the cheapest and eco-friendly alternative for getting higher yield. Biofertilizers is only the alternative way to get more production without harmful to environment. So the effect of different doses of biofertilizer (Rhizobium) on germination studies of Fenu-greek seed germination percentage, seedling growth, fresh weight and dry weight, chlorophyll, protein and soluble sugar content has been studied in the laboratory condition. There parameters increased to application when biofertilizer compared to control.

Bambusa balcooa.Roxb. is one of the most commercially important bamboo species. Some varieties of bamboo are being grown in the company’s green house. However this species is very rare and it was not cultured until now due to lack of demand and maintenance problems. In this work B. balcooa ex-plants have been established and propagated by the axillary shoot bud proliferation method. Earlier several works have been done on this plant and a protocol has been. This work emphasizes on effects of phytohormones at different concentrations and combinations upon the novel propagules that develop from the bamboo explants on placing them in multiplication media. The propagules placed in media containing cytokinins BAP (2 mg/L) and Kinetin (1 mg/L) exhibited best results of linear as well as radial growth. The other propagules in media with combinations of BAP, Kinetin and NAA were found to be dried out and did not depict noticeable growth. Comparatively next best growth pattern to the former was observed in control media that lacked phytohormones. This experiment was helpful in estimating the quantity and effect of particular plant growth regulating hormones on the Bambusa balcooa.Roxb.

A pot experiment was conducted in the green house to determine the effect of municipal solid waste on the growth of maize (zea mays). Growth parameters of percentage emergence, plant height, leaf area and number of levers per plant were collect and subjected into statistical analysis, using ANOVA and fisher’s L.S.D. at 5 % probability level. Plant growth parameters decreased with increase in cropping cycle. Similarly, maize grown on dumpsite soils did better than the control soil samples. It show increase in plant height, leaf area and number of leaves per plant at a range of 16.82 cm to 12.87 cm, 5 to 4 and 64.69 cm to 59.88 cm for the dumpsite and control samples respectively. Soil PH, organic matter (OM), total Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Sodium (Na) and Effective Cat-ion Exchange Capacity (ECEC) decreased with increase in cropping cycle respectively. The Dumpsite soil sample recorded higher mean values than the control (P < 0.05). There is every indication that municipal solid waste is beneficial to plant if only proper and careful sorting and separation of hazardous waste is done.

Opis:
Plant growth and physiological response of sesame (Sesamum indicum L.) were studied in controlled environment using normal soil and indigenous Vesicular-arbuscular mycorrhiza (VAM) fungi treated soil. The seedlings of Zea mays were inoculated with Giguspora species of VAM (Glomus fasiculatum) and the inoculum was multiplied with help of Zeamays seed bed. Sesame seeds were then inoculated into the bed and it was found that the plant height, shoots lengths, roots, biomass of shoot and roots were considerably increased in the mycorrhizal plants. The effect of VAM infection was assessed in pot experiment. In this comparative study, specific mycorrhizal fungi had consistent effects on various growth parameters such as the number of leaves, number of roots, shoot length, biomass of shoot and roots and biochemical parameters were observed at various time intervals by statistical analysis using two way ANOVA, it was confined with mycorrhizal and non-mycorrhizal infected plants. It was found that the ability of isolates to maintain the plant growth effectively in the case of mycorrhizal seedlings shows a maximum absorbtion of 0.77 ±0.2, shoot length is about 8.34 ±0.2, count of root and leaves are about 8.10 ±0.3, 5.6 ±0.3 respectively under mycorrhizal infection in 30days of analysis and had a positive effect on the growth at all intervals. Biochemical analysis were carried out to estimate the total chlorophyll, chrophyll A, chlorophyll B and Carotenoids contents and it was analyzed to be 9 ±0.5 mg/g, 8.3 ±0.5 mg/g, 3.6 ±0.5 mg/g, 4 ±0.3 mg/g respectively. At the 30th day of analysis for the mycorrhizal plants, it was found to be high in mycorrhizal seedlings which shows the symbiosis had improved the nutrient uptake of cultivated plants. Nevertheless G. fasiculatum was found to be the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.

The present research was carried out to evaluate response of Bell peppers (Capsicum annuum L.) to plant density and nitrogen fertilizer under field conditions. Plant density at four levels (20×50 cm, 30×50 cm, 20×100 cm and 30×100 cm) and nitrogen treatments at four levels (0, 50, 100 and 150 kg·N·ha-1) were applied. Plant height, lateral stem number, leaf chlorophyll content, yield, and were assessed at immature and mature stages. The results showed that vegetative growth characteristics (plant height, lateral stem number and leaf dry matter) and reproductive factors (fruit volume and fruit weight) decreased with increasing plant density, but total yield (kg·ha-1) increased with increasing plant density. The highest and lowest total yields were obtained by plant density 20×50 cm and 30×100 cm respectively. Nitrogen fertilizer was significantly affected on plant height, lateral stem number and leaf chlorophyll content. It was observed that fertilization with 150 kg·N·ha-1 resulted to the highest fruit volume and plant yield. There were significant differences between fruit volume and fruit weight by interaction between plant density and nitrogen treatments.

Salt stress is one of the most severe environmental factors that reduces and limits growth and development of plants. Abiotic stresses such as heavy metals, salinity, drought, temperature, UV-radiation, ozone causes drastic yield reduction in most of the crops. Especially salt stress affects around 20 of NaCl on germination and seedling growth of Zea mays L. Seeds of Zea mays were germinated in glass Petri- 100 × 15 mm diameter lined with blotting paper. Ten seeds were placed in each petri-dish. Petridishes were irrigated with 25, 50, 75, 100, 125, 150, 175 and 200 mM concentrations of NaCl. A control was moistened with ten milliliters of distilled water. The germination percentage, water absorption of the seeds, water uptake percentage and the growth parameters were observed. The results obtained showed that the inhibition of the germination percentage, germination rate, water uptake, growth and biomass accumulation of the seedlings were observed to decrease with increasing NaCl concentrations. At the highest level of stress both plumule and radical decreased significantly. The salt stress decreased seed germination, biomass and growth of maize seedlings due to ion toxicity, decrease osmotic potential and oxidative stress.

Opis:
The present investigation is aimed at studying the effect of ethrel on the ripening of off-season fruits of Mangifera indica L. var. Neelum. The control fruits were kept in the laboratory naturally while the experimental fruits were treated with different concentrations of ethrel (100, 200 and 300 ppm). In control fruits, partial ripening led to incomplete metabolic changes, which did not alter the presence of sourness in the fruits. Hence, they were not fit to be eaten. On the other hand, the fruits treated with different concentrations (100, 200 and 300 ppm) of ethrel ripened on 13th day, 11th day and 9th day respectively after treatment. The colour changed from green greenish to yellow and the fruits were palatable in nature. The starch decreased during ripening, both in the treated and control fruits. On the other hand, the sugar, alpha-amylase, beta-amylase, activities increased. Among the different 100, 200 and 300 ppm ethrel treatments, the 200 ppm alone had the optimum effect on the ripening of off-season fruits of Mangifera indica L. var. Neelum.
