A number of genes have been identified affecting mucilage secretory cell differentiation, including MUCILAGE-MODIFIED4 (MUM4). The mucilage secretory cells of the Arabidopsis thaliana seed coat undergo a complex differentiation process in which cell growth is followed by the synthesis and secretion of pectinaceous mucilage. Pollination triggers not only embryo development but also the differentiation of the ovule integuments to form a specialized seed coat. MUM ENHANCERS are important for seed coat mucilage production and mucilage secretory cell differentiation in Arabidopsis thaliana.Īrsovski, Andrej A Villota, Maria M Rowland, Owen Subramaniam, Rajagopal Western, Tamara L Water and fermentation in water are the best method for mucilage extraction and rice hull and coconut fiber are the best substrate for passionfruit seedling emergence and development. The parameters evaluated were: seedling emergence, speed of emergence index, leaf number, stem length, longest root length, weight of dry matter of roots and shoots. The experiment had a completely randomized design with five replications in a factorial 5 x 3 scheme (5 extraction methods of seed mucilage and 3 substrates being each parcel composed of 25 seeds. Five methods of mucilage extraction were used: water, water + sand, water + virgin whitewash blender with protected blades and fermentation in water, and three different types of substrates: rice hull, vermiculite and coconut fiber. Mucilage extraction and substrates in the seedling development of yellow passion fruit plantsĭirectory of Open Access Journals (Sweden)įull Text Available The object of this work was to evaluate different methods of mucilage extraction and substrates on passion fruit seedling emergence and development, in a mist chamber. This technique can provide a fast and simple method of obtaining the required chirp value of a grating for applications in the dispersion compensators, gain flattening in erbium-doped fiber amplifiers (EDFAs) or optical filters. The technique is based on the induced strain of an FBG due to the UV glue adhesive force on the fiber surface that causes a grating period variation and an effective index change. In this study, we have demonstrated that a uniform fiber Bragg grating (FBG) can be transformed into a chirped fiber grating by a simple UV glue adhesive technique without shifting the reflection band with respect to the center wavelength of the FBG.
