the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...

Vaccinium oldhamii Miq. is an edible berry; however, little known about its seed dormancy-break and germination. Therefore, the aim of this study was to elucidate seed-dormancy break germination characteristics V. oldhamii. The results showed that length width seeds were 2.4588 ± 0.0273 mm 1.7028 0.0248 mm, respectively, filled percentage 49.0 3.0%, 1000-seed weight 0.9453 g. Additionally, wate...

A two-year (2020-21) study was conducted to investigate the possibility of relying ten-years old pear trees grown on sandy loam soil irrigated by drip citric acid (CA), gibberellic (GA3) and humic (HA). The CA applied at concentrations 500, 1000 1500 ppm, GA3 50, 100 150 ppm HA 3, 4 5%, whereas water spray used as control. results our proved that CA, improved shoot length, thickness, leaf area ...

BACKGROUND The phytohormone gibberellic acid (GA3) is widely used in the table grape industry to induce seedlessness in seeded varieties. However, there is a paucity of information concerning the mechanisms by which GAs induce seedlessness in grapes. METHODOLOGY/PRINCIPAL FINDINGS In an effort to systematically analyze the cause of this GA3-induced seed abortion, we conducted an in depth char...

Salivary α-amylase is the most important enzyme for oral digestion of dietary starch. Therefore, regeneration of the salivary glands via a tissue engineering approach is clearly required for patients with salivary gland dysfunction. Early during seed germination, the embryo synthesizes gibberellic acid (GA3), a plant hormone that activates the synthesis and secretion of α-amylase. The purpose o...

background molecular farming is the production of important recombinant proteins in transgenic organisms on an agricultural scale. interferons are proteins with antiviral and antitumor activities and can be used for viral infections and cancers treatments. objectives this study reports the transformation of inf α2b gene in tobacco plant for the first time in iran. materials and methods interfer...

this study involves in vitro androgenesis of zea maysl. via anther culture. combination of two embryoinduction media (imss & ypm) in presence of different colchicine concentrations (0, 100, 200, 250, 300and 400 mg/l ) in the pretreatment medium (iml) andpretreatment duration (0, 3, 6 and 9 days) in twogenotypes (dh5×dh7 and eth-m82) were tested.after colchicine pretreatment, anthers were tr...

Biosorption is an alternative to traditional physicochemical means for removing toxic metals from ground and wastewaters. Biosorption of Pb(II) ion from solution was studied using Bacillus cereus M116 immobilized in calcium alginate gel in batch mode, and optimum conditions were determined. The experimental results showed that the immobilized bacterial strain was effective in removing Pb(II) io...

The colonic mucus gel layer (MGL) is a critical component of the innate immune system acting as a physical barrier to microbes, luminal insults, and toxins. Mucins are the major component of the MGL. Selected microbes have the potential to interact with, bind to, and metabolize mucins. The tolerance of the host to the presence of these microbes is critical to maintaining MGL homeostasis. In dis...

An efficient and highly reproducible protocol for micropropagation of bird eye chilli Capsicum frutescens was attempted. Murashige and Skoog (MS) medium containing 0.5-3.0 mgl(-1) of 6-benzyladenine (BA), 2-isopentenyl adenine (2iP), kinetin and 0.5-2.0 mg l(-1) of indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) along with 1 gl(-1) activated charcoal (AC) were used for shoot regeneratio...
