PENGARUH PEMBERIAN PUPUK OSMOCOTE TERHADAP PERKECAMBAHAN 3 GENOTIPE ADENIUM
2018
<em>This study aims to find out the effect of osmocote fertilizer to the germination of three genotypes of Adenium and also to compare the germination among three Adenium varieties. Factorial experimental method was being used in this pot experiment which designed by using Factorial Randomized Group Design. First factor is the 3 types of Adenium, while the second factor is 6 dosage levels of Osmocote. The results of this research showed that the addition of various dosage of the osmocote significantly affected the germination of 3 types of adenium. The effective dosage of Osmocote for adenium germination is one gram while the white flower adenium has the best germinability.</em>

Study of nucleation-growth processes of ettringite, alone or in a tricalcium aluminate/calcium sulfate system
2019
Ettringite Ca6Al2(SO4)3(OH)12.26H2O is one of the main hydration products of cements but despite the importance of this compound for cement chemistry, laws governing its precipitation processes have been poorly studied. This PhD thesis was entirely focused on the study of ettringite and on its nucleation-growth mechanisms.Ettringite precipitation was first studied alone from supersaturated ionic solutions. Experiments were designed in order to study separately processes of nucleation and growth. The Classical Theory of Nucleation was applied and allowed the determination of the interfacial energy of ettringite. A global description of ettringite precipitation process has been suggested. It …
Control of Portulaca oleracea by boldo and lemon essential oils in different soils
2015
Soil characteristics influence plant growth and can affect the phytotoxicity of the essential oils. In this study chemical composition and herbicidal activity of Peumus boldus Mol. and lemon essential oils in different growing medium against Portulaca oleracea L. was investigated. Ninety-four compounds accounting between 95.5 and 99.8% of the total essential oil were identified by gas chromatography-mass spectrometry in boldo and lemon essential oils. Ascaridole (31.56. ±. 0.15%), p-cymene (21.58. ±. 0.09%) and 1,8-cineole (12.57. ±. 0.13%) were the main compounds in P. boldus whereas large amount of limonene (59.28%) followed of β-pinene (12.96%) and γ-terpinene (10.92%) were found in lemo…
Testing safety of germinated rye sourdough in a celiac disease model based on the adoptive transfer of prolamin-primed memory T cells into lymphopeni…
2014
The current treatment for celiac disease is strict gluten-free diet. Technical processing may render gluten-containing foods safe for consumption by celiac patients, but so far in vivo safety testing can only be performed on patients. We modified a celiac disease mouse model to test antigenicity and inflammatory effects of germinated rye sourdough, a food product characterized by extensive prolamin hydrolysis. Lymphopenic Rag1−/− or nude mice were injected with splenic CD4+CD62L−CD44high-memory T cells from gliadin- or secalin-immunized wild-type donor mice. We found that: 1) Rag1−/− recipients challenged with wheat or rye gluten lost more body weight and developed more severe histological…
Microwave effects on germination and growth of radish (Raphanus sativusL.) seedlings
2002
Abstract Germination of radish seeds was delayed and reduced by low-power microwave exposure at 10.5 and 12.5 GHz. Irradiation decreased also hypocotyl growth rate. These effects were increased by rising of the microwave power and by the vertically polarised electromagnetic field. When the irradiation was suspended the seedling growth recovered.
Propagation techniques for three Mediterranean native shrubs with potentential as ornamental outdoor plants
2006
Grande are three Mediterranean shrubs with interesting ornamental features. The exploitation of wild plants for ornamental purposes implies knowledge on the factors influencing the propagation methods. To study the influence of temperature on germination, seeds of Teucrium flavum, Prasium majus and Micromeria fruticulosa were germinated in incubators at constant temperatures of 14, 20, 24 and 28°C. Highest germination, 45 % and 86%, occurred at 20°C in Teucrium flavum and Prasium majus, respectively. Micromeria fruticulosa seeds subjected at 24 or 28°C had a germination percentage significantly higher than at 20 or 14°C. To study the influence of auxin treatments on vegetative propagation, …
