In the present research paper studies have been made on fertilizer factory wastes on percent seed germination, root and shoot length of plants and development of root-knot galls by Meloidogyne incognita in five cultivars of tomato. Though all the cultivars showed almost similar impact of fertilizer wastes on seed germination, plant growth and resistance for root-knot disease with little variation. Percent germination of seeds and plant growth was found decreased while the root-knot index was increased along with the increase in concentration of fertilizer wastes.

In this study, we aimed at examining the potential to stimulate growth in Pennisetum clandestinum using four isolated bacterial strains from soils obtained from a Colombian tropical silvopastoral system. We previously identified genetically the strains and characterized two plant growth promotion activities. We found that the four bacterial strains were phylogenetically associated with Klebsiella sp. (strains 28P and 35P), Beijerinka sp. (37L) and Achromobacter xylosoxidans (E37), based on partial 16S rRNA gene sequencing. Moreover, the in vitro biochemical assays demonstrated that the strains exhibited some plant growth promotion mechanisms such as 1-aminocyclopropane-1-carboxylic acid deaminase activity and indole compound synthesis. Notably, bacterial inoculation under greenhouse conditions showed a positive influence on P. clandestinum growth. We found a significant (p < 0.05) effect on root and shoot length, and shoot dry weight. Shoot length increased by 52% and 30% with 37L and 35P, respectively, compared to those without inoculation treatment. Similarly, the use of 37L and 28P raised shoot dry weight values by 170% and 131%, respectively. In root development, inoculation with strains 37L and E37 increased root length by 134% and 100%, respectively. Beijerinckia sp. 37L was the most effective of the four strains at increasing P. clandestinum biomass and length.

In vitro seed germination and growth of seedlings was tried with three varieties of black gram (Vigna mungo (L.) Hepper) viz. Vamban-3, Nirmal-7 and T-9 after ultraviolet-B irradiation (UV-B = 2 hours once with 1 hour recovery time @ 12.2 kJ m-2 d-1; ambient = 10 kJ m-2 d-1). Unstressed and UV-B stressed VAMBAN-3 and T-9 seeds both in dry and wet conditions responded to in vitro germination. Unstressed NIRMAL-7 failed to germinate under in vitro culture. UV-B stressed NIRMAL-7 responded to in vitro culture. UV-B irradiation enhanced seedling height at both dry and wet conditions in VAMBAN-3 followed by NIRMAL-7 compared with controls. Root and shoot length of UV-B stressed VAMBAN-3 and NIRMAL-7 performed five to six times better than control. Root and shoot length of T-9 was reduced (2.61 to 8.69 %) below control after UV-B exposure. UV-B stressed VAMBAN-3 under dry and wet exposure accumulated three to six times more plant biomass over controls. UV-B stressed NIRMAL-7 and T-9 dry seeds accumulated less plant biomass by 70.86 % and 12.39 % respectively than their controls. NIRMAL-7 and T-9 under dry UV-B exposure produced two times more leaves than control.Int J Appl Sci Biotechnol, Vol 4(1): 117-129

Iron deficiency is one of the limiting factors of plant growth. In recent years nanotechnology has attracted attention to producing forms of iron that are available to plants. Chitosan, which is widely used in agriculture due to its unique properties, has metal-binding abilities. We decided to study nanomagnetite and chitosan's combined action to improve seed germination and growth of wheat (Triticum aestivum L.). The thumbnail method was used in the study. The seeds were treated with magnetite suspension and chitosan solutions before planting. An increase in plant growth, root, and shoot length of plants was found in all seed treatment methods (chitosan, nanomagnetite, and combined action). This increase was significantly dependent on the concentration of chitosan. However, chitosan and magnetite combination was 1.3 times more effective for seed germination than pure chitosan or magnetite. A mechanism based on chitosan's ability to promote the better transfer of iron ions to plants is proposed. However, further investigation for the optimization of chitosan/magnetite proportions for improving seed growth is required.

Basil (Ocimum basilicum L.) plants have multiple uses, ranging from spice to cosmetic purpose, besides being a source of essential oil and aromatic. These plants were commonly propagated by seed, however, few agrotechnologies are used to enhance the seed germination and initial growth in this crop. For this reason, our research aimed to evaluate aspects of seed germination of Ocimum basilicum L. cv. Limoncino, subjected to different bioregulators applied via substrate imbibition. The experiment was carried out in completely randomized design, with four treatments, as follows: T1: control (distilled water), T2: T13 a solution of a product formulated based on indolbutyric acid + naphthalene acetic acid + gibberellic acid (0.2 mL L-1, Liko Química), T3: gibberellic acid (0.5 mM L-1, progibb-400®) and T4: brassinosteroids (0.1 mM L-1). We evaluated: germination rate, germination speed index (GSI), first count, root and shoot length and chlorophyll a, b, total and carotenoids. The bioregulators did not influence germination, first count, GSI and photosynthetic leaf pigment, but application of gibberellic acid and brassinosteroids improve the shoot and root length, respectively. The gibberellic acid and brassinosteroids are promising bioregulators for stimulating initial basil growth.

Effect of different doses of aqueous extracts of walnut leaf was studied on germinating seeds and early seedling growth of wheat variety (cv. VL-616) recommended for hills under West Himalayan agri-silvi system. Seven treatments comprised of distilled water control (0%), 10%, 20%, 30%, 40%, 50% and 60% concentration of leaf extracts were treated. The effect of aqueous extracts was found inhibitive; indicate a direct proportional relationship with concentration dependent manner on seed germination and subsequent seedling growth of wheat. The wheat variety exhibited extent of phytotoxicity at 60% extracts application in comparison to untreated control. Invariably there was a decrease in first count, germination, seedling root and shoot length, seedling fresh and dry weight and vigour index with increasing aqueous extracts concentration on germinating wheat, however the shoot length was observed maximum at 60% concentration.

The increasing public concern about municipal solid waste (MSW) due to its impact on health and environment induces people to think about more ways of recycling this waste. These days, people strive to find more appropriate methods and processes to treat MSW for its proper management and disposal. Composting process is the most appropriate method of recycling used to get rid of organic fractions. The most important concern is the production of compost leachate. This study was designed to check the potential of compost leachate as a chemical fertilizer and to compare it with commercial fertilizer. Different dilutions of compost leachate and commercial fertilizer were used to check their effects on seed germination of wheat and maize crop and the initial root and shoot length measurement of these crops. Germination index, germination inhibition and germination rate were also evaluated in different experimental trials with variation in leachate dilution. The results showed best root, shoot length and seed germination at low quantity of leachate sample. The obtained results showed that leachate has better fertilizer qualities as compared to commercial fertilizer. Moreover, it is more economical and environment friendly. It also helps in maintaining the structure of soil and conditions the soil.

The present study was carried out to evaluate the response of different bioagents/biofungicides and growth regulators on seed germination and early seedling growth of sunflower. Eleven (11) treatments were established for the present investigation. Higher germination was observed in T5, T6/T7, T10 and T11 treatments in contrast to other treatments. Treatments T7, T3 and T11 were found significantly better than all other treatments. Generally, root and shoot length increased with the advancement of growth stages. T4 showed higher number of secondary roots in comparison to all other treatments. The shoot length and root length in all the cases (irrespective of the cultivars: DRSH-1, DRSF-108, LSFH-171) were highly influenced by the bioinoculants and chemicals; however, influence of bioagents was found better than the chemicals. Similarly, the seedling weight in 96 hours after sowing and 144 hours after sowing in all the cultivars was reported higher than when the seeds were treated with bioinoculants, which reflected the efficacy of the bioinoculants compared to others.

Abstract: Both protein and starch hydrolysis contribute to the effective mobilization of seed reserves to trigger seed germination. We studied the activities of hydrolytic enzymes in germinating seeds of mung bean (Vigna radiata) exposed to cadmium stress at 0, 25, 50, 75, 100 mg.L-1. Exposure to Cd stress decreased the seed germination rate and early seedling growth traits, including root and shoot length and plant fresh and dry biomass compared to control. The adverse effects of Cd were more prominent in terms of shoot length than root length. Seedling α-amylase and protease activities exhibited significant reductions with increasing Cd dose. We also recorded Cd-induced reduction in total soluble proteins and sugars while the concentration of free amino acids exhibited an increase. Above all, a decrease in the hydrolysis process of reserve carbohydrates, proteins and impaired reserve translocation contributed to the inhibition of seedlings’ germination and early growth traits.

Effects of progesterone and β-estradiol on morphologic (germination velocity, root and shoot length) and biochemical (activities of α-amylase, superoxide dismutase, peroxidase and catalase, H2O2 content, lipid peroxidation) parameters during germination and post-germination stages of chickpea seeds were studied. The seeds germinated at various hormone concentrations (10 - 4, 10 - 6, 10 - 9, 10 - 12, 10 - 15 M) were harvested at the end of the 1st, 3rd, and 5th day. With comparison to the control, these hormones caused an increment in the number of germinating seeds at the end of days 1 and 3 by accelerating the seed germination. Root and shoot lengths were augmented by both hormones at all hormone concentrations tested. The highest elongation was recorded in 10 - 6 M progesterone and 10 - 9 - 10 - 12 M β-estradiol. Similarly, activities of α-amylase and superoxide dismutase were increased by all concentrations of both hormones, and maximum increases were obtained with 10 - 6 M progesterone and 10- 9-10- 12 M β-estradiol. In the case of superoxide dismutase activity, not only the H2O2 content but also the peroxidase and catalase activities increased. Lipid peroxidation decreased depending on an increase in the antioxidant enzyme activities. In the present study, it was demonstrated that progesterone and β-estradiol even at low concentrations increase the germination velocity and resistance to stress conditions by changing the activities of some biochemical pathways.
