Seed biology of Andrographis elongata T. And. (Acanthaceae) – a valuable endemic medicinal plant of India
The present investigation deals with the seed biology of an endemic medicinal plant species, Andrographis elongata T. And. of Acanthace family. Its leaves, whole plant, root flowers and seed are used as medicine. Its major bitter principles are 2¢-oxygenated flavones. It is useful in the treatment of snake bite, diabetes, antidiabetic malarial fever, diuretic, skin […]
Effect of planting depth on the germination and initial growth and development of shea (Vitellaria paradoxa C.F. Gaertn.)
The study was carried out to assess the effects of planting depth on the germination and initial growth and development of Shea (Vitellaria paradoxa C.F. Gaertn.) seedlings, at the Faculty of Renewable Natural Resources mango plantation, University for Development Studies-Nyankpala campus. The specific objectives were to determine the germination percentage and to assess the effects […]
Allelopathic effects of Mexican sunflower [Tithonia diversifolia (Hemsl) A. Gray] on germination and growth of Spiderplant (Cleome gynandra L.)
Allelopathy refers to both beneficial and harmful effects of one plant on another plant by the release of chemicals from plant parts through leaching, root exudation, volatilization, residue decomposition and other processes in both natural and agricultural systems. Tithonia diversifolia contains allelochemicals that inhibit or stimulate growth of agricultural crops. A study was conducted to […]
Rapid in vitro clonal propagation of a hybrid muskmelon (Cucumis melo L.) cultivar from seedling explants
An investigation was undertaken to develop a reliable strategy for large scale multiplication of a hybrid cultivar of muskmelon through in vitro clonal propagation. Best in vitro seed germination was observed in MS medium containing 0.5 mg/l GA3. Two explants excised from axenic seedlings were tested for shoot proliferation and leaf node showed better shoot […]
Investigation on the effect of cassava effluent-polluted soil on germination, emergence and oxidative stress parameters of Telferia occidentalis
The effect of cassava effluent-polluted soil on germination, emergence and oxidative stress parameters of Telferia occidentalis from soil exposed to the effluent over a long period of time was studied. Telferis occidentalis leaves from soil samples devoid of cassava effluent served as the control. T. occidentalis seeds from soil samples devoid of cassava effluent-polluted soil […]
Extraction of β-galactosidase and β-glucosidase from the seeds of Tamarindus indica.
The enzymes β–galactosidase and β–glucosidase were extracted from the tamarind seeds using different buffers at different pH. Highest activity was obtained with 10 mM sodium acetate buffer, pH 5.6 and 10 mM tris buffer, pH 7.4. The effect of NaCl and Triton X–100 at different concentrations on the extraction of the enzymes indicated 10 mM […]
Allelopathic potential of Sesbania grandiflora Pers. on germination of Cajanus cajan Millsp. (Redgram) varieties
In the present study, the leaf extracts of Sesbania grandiflora Pers. showed inhibitory effects on seed germination, plumule length, radicle length, fresh and dry weight in redgram (Cajanus cajan Millsp. var. Vamban 2 and Cajanus cajan var. Vamban 3). The allelopathic effect of leaf extracts of S. grandiflora decreased the seed germination of Cajanus cajan […]
Germination performance of some legume crops under varying soil water available capacities
A laboratory attempt was made to evaluate germination performances of three lentil cultivars namely Nineveh, Adlib and Baraka, besides Common Vetch and Mungbeans under varying soil water availabilities. Soils were moistened to 100, 75, 50 and 25% of its water available capacity and were used as germinating media. Germinating seeds in 0% soil AWC depletion […]
Germination performance of some legume crops under varying filter paper moistures
Adverse effects of water stress without ions interactions in Baraka, Adlib and Nineveh lentil cultivars have been investigated. Results showed that germination under saturation (0 AWC depletion %) was the paramount treatment as it manifested the highest values. It profoundly surpassed that of 25, 50, and 75 AWC depletion % in terms of final germination […]
Evaluation of Ameliorative Role of Biochar on Chromium Toxicity in Bottle Gourd
The present attempt was made to elucidate the ameliorative role of Biochar (BC) in response to chromium toxicity on bottle gourd seed germination. In this study, seeds were grown in pot experiment with six treatments (Control, Low Cr-20mg/kg, High Cr-100mg/kg, BC-2%, BC-2%+Low Cr-20mg/kg, BC-2%+High Cr-100mg/kg). Harvesting was done after 40 days of development. Growth parameters, […]
