AbstractSoil salinisation is an important factor limiting the cultivation and distribution of Prunus mume. Therefore, identifying the regulation mechanism of salt tolerance of P. mume will promote its cultivation and molecular breeding. In this study, the garden tree species P. mume ‘Meiren’ was investigated, with a soil NaCl content (w/w) of 0.3%. Photosynthetic gas exchange parameters, relative electrical conductivity, malondialdehyde, osmoregulation substances, and antioxidant enzyme activity were measured in the early (3d), middle (10d), and late (30d) stages of stress. Salt treatment was applied for 0 h, 6 h, 24 h, and 72 h; following this, the gene library was constructed from the leaves. The results showed that the CBL-CIPK, mitogen-activated protein kinase, calcium-dependent protein kinase, and abscisic acid signalling pathways were involved in salt stress signal transduction of P. mume. Furthermore, bHLH, WRPK, ERF, and MYB were identified as potential key transcription factor families of salt tolerance in P. mume. Combined with determined physiological responses, the results showed that early salt stress inhibited the activities of RuBisCO, chlorophyll synthase, glutamyl tRNA reductase, divinyl reductase, and magnesium chelatase; resultantly, this led to a reduction in the photosynthetic rate. Also, it was found that P5CS, SS, LEA, and dehydrin regulated the synthesis of proline, soluble sugar, and macromolecular protein to alleviate osmotic stress. POD gene plays an important role in scavenging reactive oxygen species due to its regulation of POD activity. The findings of this research reveal the internal mechanism of the physiological response and provide a foundation for the construction of a genetic regulatory network in response to salt stress in P. mume.

Aims: The research aimed to study the response of agronomy and physiology of rice plant to different silica sources. Study Design:  Completely randomized design. Place and Duration of Study: The research was conducted in screen house of Faculty of Agriculture, Andalas University, Padang, Indonesia from April to December 2018. Methodology: Completely randomized design was used in the assay. The treatment was 10 Si sources (No silica, Si 1 ppm, Si 2 ppm, Si 3 ppm, husk charcoal 50 g/plant, husk charcoal 100 g/plant, husk charcoal 150 g/plant, husk ash 50 g/plant, husk ash 100 g/plant, husk ash 150 g/plant). The variety was Anak Daro. Each treatment was replied 3 times so that 30 experimental units were obtained. The data was analysed by using F test in 5% and followed by Duncan’s Multiple Range Test (DNMRT) in 5%. The data analysis using software Statistic Tool for Agricultural Research (STAR). Results: Silica sources affected the agronomic and physiological characters of rice plant. 2,3 ppm of silica, 100 and 150 g of husk charcoal and 100 g of husk ash were the best silica source for plant height. 3 ppm silica affected the number of tiller of rice plant. In number of chlorophyll, 150 g of husk ash affected the number of chlorophyll A and the silica sources did not affect the number of chlorophyll B. Conclusion: The sources of silica affected the agronomic and physiological response of rice plant which can be useful for rice cultivation in the region.

Wukirsari Village, Cangkringan District is belong to Merapi Mountain’s slopes which located between the Gendol River and Yellow River. Nowadays, we faced the problem of anorganic fertilizer overused such as Urea, ZA, TSP/SP-36 and KCl in agriculture land. The effort to return the soil organic compound can be done by added some organic compounds or microbial bio -organic fertilizer. Sludge is fermented biodigester yield and it has lost its gas. The aim of this research was to understand the physiological response and optimum dose of biogas as planting medium to ‘Segreng’ Rice planted in the rice field of Wukirsari Village, Cangkringan District, Sleman Regency. This research was done on greenhouse scale and rice field scale. The treatment given on 0; 1; 1,5; 2 and 2,5 liters per 100 m2 of rice field areas, and given on 0; 4; 8; 12; and 24 ml per 5 kg soil on polybags. Data were taken in three repetitions. The vegetative growth parameters included plant height, number of leaves, number of seedlings and chlorophyll content, while generative growth parameters measured included NRA levels, dried biomass including crown/stem, roots, filled grains, empty grains, and total weight and number of filled grains, empty rains, and the number of panicles. The result were tested with ONE WAY ANOVA (Analysis of Variance) with SPSS version 19 for Windows and followed by Duncan's Multiple Range Test with 95% significance level (α = 0.05). Generally, the result showed that biogas sludge can increase the vegetative and generative growth of rice plant ‘Segreng’ on polybag scale and rice field scale. The rice plant on polybag with 4 ml biogas sludge was significantly different on the vegetative growth and chlorophyll content, while the rice plant on polybag with 8 ml biogas sludge was significantly different on the generative growth and NRA levels.
