Cucumis melo L. is one of the most economically important horticultural crops worldwide. However, low plant regeneration frequency of this plant during genetic transformation is the major hurdle for applying biotechnological approaches. Hence, this study aimed to evaluate the effect of 6-benzyladenine (BA), cefotaxime (CTX), kanamycin (KAN), and indole-3-acetic acid (IAA) on the regenerati...
Dendrobium merupakan anggrek yang memiliki nilai ekonomis tinggi karena ketertarikan dari warna dan bentuk bunga. Permintaan ketersediaan terbatas sehingga metode kultur in vitro sangat dibutuhkan untuk memperoleh dengan jumlah banyak pertumbuhannya dalam waktu singkat. Media MS cair eksplan protocorm like bodies (PLB) dapat digunakan menghasilkan pertumbuhan lebih optimal. Penelitian ini bertu...
in order to study the effect of foliar application of zinc and iron on germination of soybaen seed under different level of irrigation, an experiment was conducted in 2009 at shahrekord agricultural research center. main factor was including of four levels of drought stress as irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from class a evaporation basin) and sub factor was inc...
Silicon (Si), as a beneficial or quasi-essential element, has different effects on physiological and biochemical processes in plants. But, many greenhouse growers in Iran, especially in soilless system (hydroponic), do not use Si in their recipe and fertilization program. This experiment was conducted to assess the effects of foliar application of different Si levels (0, 50, 100 and 150 mg/L) o...
Salinity is one of the most important non- biological stresses which limit the production of agricultural yields in dry and semi arid regions. Humic acid as an organic acid and ascorbate as a powerful antioxidant can improve yield of plants under salt stress. In order to investigation effects of salinity and its interaction with ascorbate and humic acid on growth, photosynthetic pigments conten...
One of the negative effects of water stress on growth and crop production is micronutrient uptake reduction by plant root. Therefore, to evaluate the effect of foliar application of Fe and Zn on some physiological and morphological characteristics of red bean (Akhtar cultivar) under drought stress this experiment was designed as a split plot in a completely randomized block design with three re...
sugar type and growth regulators are essential fundamental components of tissue culture media. in this study, different concentrations of some carbohydrate and growth regulators during anther culture and producing somatic embryo of datura stramonium l. was investigated in ms medium. the ms medium supplemented with 0.5 mgl-1 kinetin and 2 mgl-1 2,4-d, and also the medium supplemented with 0.25 m...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...
A multicommuted flow system is proposed for spectrophotometric determination of hydrosoluble vitamins (ascorbic acid, thiamine, riboflavine and pyridoxine) in pharmaceutical preparations. The flow manifold was designed with computer-controlled three-way solenoid valves for independent handling of sample and reagent solutions and a multi-channel spectrophotometer was employed for signal measurem...
