Jatropha curcas is a plant that is used as an alternative energy for fossil fuel replacement because of it’s high oil content. Jatropha curcas seeds have 30-40% oil content. The purpose of the study was to improve the seed quality and to enhance seedling growth of Jatropha curcas after storage using plant growth regulator. This study used factorial design based on Completely Randomized Design with two factors and 3 replications. The first factor was seed storage which consist of 2 levels : A1 = seed storage in 2015, A2 = seed storage in 2016. The second factor was plant growth regulator level which consists of 6 levels : B1=GA+NAA 0 ppm, B2= GA+NAA 20 ppm, B3= GA+ NAA 40 ppm, B4= GA+NAA 60 ppm, B5 = GA+NAA 80 PPM, B6 = GA+NAA 100 ppm. Parameters measured were seed germination, vigor index, growth rate, plant height and the number of leaves. The data were analyzed statistically by analysis of variance and followed by Tukey test and Polynomial Orthogonal. The result showed that seed germination, vigor index and growth rate were significantly affected by storage treatment and invigoration using plant growth regulator treatment. Invigoration using auxin and gibberellic acid 40 ppm has the highest result of seed germination, vigor index and growth rate. There was no influence of seed storage and invigoration with plant growth regulator treatment on plant height and number of leaves. Keywords : Jatropha curcas, invigoration, plant growth regulator.

Purpose. To develop the element for regulating the formation of seed yield and the seeding properties of Bromus inermis through the application of Medax Top growth regulator from the time of tillering to the stem elongation of seed crops. To establish its effect on the growth of plants, their height, productive density, the number and mass of grains in inflorescences, the power of growth and seed germination. Methods. Field, visual, measuring, weight, quantitative, test sheaf method, laboratory, mathematical and statistical. Results. The results of scientific research aimed at creating favorable conditions for the formation of seed productivity of Bromus inermis and its seeding properties through the application of Medax Top plant growth regulator in the sixth-eighth period of organogenesis, i.e. from the beginning of tillering to the stem elongation of seed crops are presented. Its effect on increasing plant resistance to lodging, reducing plant height, increasing productive shoot formation, the number and mass of grains in inflorescence, improving seeding properties, in particular, the power of growth and seed germination, which contributed to the formation of seed yield of 343—354 kg/ha or 47—58 kg/ha more compared to the control without application of the plant growth regulator. Conclusions. Application of Medax Top plant growth regulator at the rate of 0.5—1.0 l/ha in the seed crops of Bromus inermis of Vseslav cultivar during the growing season is effective from the beginning of tillering to the stem formation, it contributes to an increase in its seed productivity by 5.0—21.2 % and provides conditional net profit of 5,179—5,288 UAH/ha.

This study aims to determine the effect of the dose of plant growth regulator (PGR) Gibgro-20T on the growth of Eucheuma cottonii in-vitro. The experimental method used was a Completely Randomized Design (CRD) treatment with a Gibgro-20T dose of 0 ppm (control), 5 ppm, 10 ppm, and 15 ppm. The results showed that the highest weight growth rate (RGRW) obtained at 10 ppm PGR dose, which is 1.27% per day. Meanwhile, the highest length growth rate (RGRL) obtained at a dose of 10 ppm, which was 1.72% per day, and the highest RGRL was significantly different from the control (0 ppm) and 5 ppm but was not different real (P<0.05) with 15 ppm treatment. Using Gibgro-20T at doses of 5, 10, and 15 ppm, however, doses of 10 and 15 ppm show higher length growth.

Abstract Seeding is the most important and quite challenging stage in seed/TSS cultivation. Plant growth regulator (PGR) seed priming has the potential to enhance the quality of TSS seedlings. The research had been conducted in the greenhouse of Agriculture Faculty, UGM, from February to April 2020. The factorial treatments of shallot cultivars (Tuk-Tuk, Lokananta and Sanren) and seed treatments (soaking seed with GA3 100 ppm and NAA 50 ppm for 12 hours and untreated seeds as control) were assigned in the RCBD with four replications. Each experimental unit was consisted of 728 seeds per cultivar. Both treated and untreated seeds were sown in soil blocks. The data were analyzed using ANOVA and continued with Tukey HSD procedure at α=0.05. The results showed that PGR priming on seeds significantly increased the germination percentage, plant height, leaf number, leaf area, and hypothetical vigor index of the three cultivars at six weeks after sowing. However, there was no significant difference in the fresh weight and dry weight of seedlings. This research implied that soaking seeds in GA3 100 ppm and NAA 50 ppm for 12 hours could improve seed germination and TSS seedling growth. Additional fertilizers are perhaps needed in soil blocks to increase the effect of hormones on the seedlings.
