The use of environmental and sustainable ornamental flower production practices with renewable resources has drawn worldwide interest. One of these renewable resources is vermicompost (earthworm castings). In recent years, increasing demand for improving environmental quality have focused on the importance of Plant Growth Promotion Bacteria (PGPBs) in agriculture. Vermicomposts also help microbial agents function effectively in soil. In this study, a total of six treatments [A: PGPB formulation, B: Not autoclaved vermicompost, C: Autoclaved vermicompost, D: Not autoclaved vermicompost+PGPBs, E: Autoclaved vermicompost+PGPBs, F: Control (untreated bacteria and vermicompost)] were tested for their effects on the plant growth and development parameters in gladiolus (Gladiolus grandiflorus L. ‘Red Beauty’) in greenhouse condition. Vermicompost was added to the related pots by dissolving in water. After the addition of vermicompost, PGPB formulation was given immediately to related pots. All the treatments were applied to soil once in three leaf stage, close to the plant root zone. Parameters in terms of yield and quality attributes of plant and corm were determined and analyzed. The treatment A increased in plant height of gladiolus of 24.55% rate. The earliest times to flowering was determined in E application (100.48 day), which also increased in corm diameter with rate of 17.41% and number of corms and cormels with rate of 151.83% according to F application. Results indicated that the treatment E promoted overall better performance as compared to other treatments diameter of flowers for number of leaves per plant, number of florets per spike, stem diameter, spike length, fresh and dry weight of flowers, the number and diameter of corm. Autoclaved vermicompost can be good choice in gladiolus cultivation but it should be enriched with PGPB.

“…During the rapid expansion of corm and cormels, starch and sugar levels increased sharply 32 . Recently, we have shown that induction of starch metabolic genes ( the small/large subunit of ADP-glucose pyrophosphorylase ; GhAGPS1 / GhAGPL1 ) stimulates corm development and cormel numbers 33 , 34 . Additionally, JA could promote corm expansion, and the expression pattern of GhLOX1 ( LIPOXYGENASE ), a key JA biosynthesis gene, coincides with corm development 35 .…”

Understanding corm development in flower bulbs is of importance for securing the quality of cut flowers and propagation of commercial stocks. Gladiolus is one of the most popular bulb plants worldwide. Its corm development is characterized by starch accumulation. Previous research has shown that phytohormones (especially gibberellin (GA)) are involved in tuber development. However, the relationship between abscisic acid (ABA)/GA and starch during corm development remains unclear. To gain deeper insights into the biological process of corm development, we performed a detailed anatomical characterization of different stages of corm development and analyzed phytohormone levels. Our study showed that corm development is linked to hormones (ABA and GA) and carbohydrates (sucrose and starch). Exogenous hormone treatment and silencing of endogenous hormone biosynthesis genes indicated that ABA positively regulates corm development, while GA acts as an antagonist of ABA function. A sucrose synthase gene (GhSUS2) was shown to be involved in the antagonism between ABA and GA. GhSUS2 was upregulated by ABA and downregulated by GA. The increase in the transcript level of GhSUS2 coincided with the development of corm/cormels. Silencing of GhSUS2 repressed corm development and starch accumulation. In conclusion, we propose that GhSUS2, an essential enzyme in sucrose degradation, is differentially regulated by ABA and GA and controls corm development in Gladiolus.

“…AGPLI写法核对，给原图 leaves is related to the nitrogen content primarily (Evans et al 1989). Sucrose and starch are the main products of carbon assimilation, and SUS and AGPase are widely recognized as the vital enzyme of sucrose metabolism and starch biosynthesis, respectively (Chen et al 2012;Seng et al 2016). In this study, the photosynthetic rate, stomatal conductance and intercellular CO 2 concentration in leaves of the transgenic plants were significantly higher than in those of WT under Ca(NO 3 ) 2 treatment, and the content of sucrose and starch were significantly increased (Figs.…”

Nitrogen is an important nutrient for plant development. Nitrogen and carbon metabolisms are tightly linked to physiological functions in plants. In this study, we found that the IbSnRK1 gene was induced by Ca(NO 3) 2. Its overexpression enhanced nitrogen uptake and carbon assimilation in transgenic sweetpotato. After Ca(15 NO 3) 2 treatment, the 15 N atom excess, 15 N and total N content and nitrogen uptake efficiency (NUE) were significantly increased in the roots, stems and leaves of transgenic plants compared with wild type (WT) and empty vector control (VC). After Ca(NO 3) 2 treatment, the increased nitrate N content, nitrate reductase (NR) activity, free amino acid content, and soluble protein content were found in the roots or leaves of transgenic plants. The photosynthesis and carbon assimilation were enhanced. These results suggest that the IbSnRK1 gene plays important roles in nitrogen uptake and carbon assimilation of sweetpotato. This gene has the potential to be used for improving the yield and quality of sweetpotato.
