This research used gamma ray irradiation on low doses (micro mutation). The aim of this research was to know the respons of doses level bymicro mutation on gamma ray irridation to the growing and development of Argomulyo variety of Glycine max (L) Merr (M1), the seeds isirradiated by gamma ray by micro mutation was 0 Gy, 50 Gy, 100 Gy, 150 Gy, and 200 Gy. Variation that obtained of each characters atgeneration M1 and M2 influences plants growth and development either through qualitative and quantitative that finally will influence plantsproduction. The average highest genetic variation at M 2 generation of soybean was on 200 Gy doses. Results of the research indicated thatgamma ray irradiation on 200 Gy doses was effective caused of plant variation genetic.

Bulbs of localSamosir Shallot with the weight ranging from 1,3 to1,7 g were irradiated by several doses of gamma rays in order to investigate the radiosensitivity and the effects of irradiatons on the plants. Dry bulbs 2,5 months after harvest were exposed to gamma raysradiation ranging from 0 Gy to 20 Gy to determine their responses to radiation stress and the effective radiation dose for identification of Lethal dose 50 (LD50). Percentage of shoot growth was measured on 35th days after planting. The variation in morphological and agronomic characters were also determined. The results indicated that increasing doses of gamma irradiation had significant effect on shoot growth. Increasing in gamma rays doses from 0 Gy to 11Gy had little effect on percentage of shoot growth.With the increase in radiation dosesabove 11Gy, agreat reduction in percentage of shoot growth was observed in irradiated bulbs as compared to control. The LD50 values of local Samosir Shallot determined from linear regression analysis (using Curve-fit Analysis software) based on percentage of regenerated shoot growth was 11.60 Gy. There were also siqnificantdifferenciesbetweenregenerated plants growth from irradiated bulbs and control (unirradiated).Treated bulbs produced shorther plant lenght and less leave number

To fulfill the demand of soybeans, the expansion of the planting area can be one of the choices through the conversion of marginal land by utilizing suboptimal land, such as saline soil. One of the plant breeding techniques to obtain tolerant plants to salinity is the use of chemical mutations, such as colchicine. The study aimed to reveal the effect of salinity on the characters of soybean plants (mutated with colchicine) and the effect of colchicine on the number of chromosomes and ploidy level. This study was conducted from January to March 2020 and carried out in the plastic house of Faculty of Agriculture, Universitas Sumatera Utara. The experiment was arranged in a Randomized Block Design with salinity levels (0 dS.m-1, 2 dS.m-1, 4 dS.m-1, 6 dS.m-1) as treatments and consisted of ten replications in each treatment. The result showed that the soybean plants were not successfully induced by colchicine at a concentration of 0.04 % with soaking duration of 10 hours, as indicated by the number of chromosomes and analysis of ploidy level. The soybeans that had been induced were planted in saline soil. There were significant effects observed on the productive branch, number of filled pods, and the weight of seeds per plant. Colchicine treatment did not successfully affect the number of chromosomes of soybeans but had an impact on the chromosome pattern. In addition, the salinity treatment of 4 dS.m-1 significantly affected the number of filled pods compared to the treatment of 6 dS.m-1.

The rate of change in forest area into plantations tend to be greatly improved from year to year. As a result of forest land will be increasingly threatened its existence as it is converted to plantations. For that to know how the ratio of the absorption of CO2 by growers compared with forests. The purpose of this research were to know the carbon content in each section rubber tree (Hevea brasiliensis Muell. Arg.) and to determine the potential of carbon reserves in the rubber tree (Hevea brasiliensis Muell. Arg.) age of 10 years in people plantation Serdang Bedagai. The method of estimaty carbon stocks had done destructive ends. Selection of plant samples carried out with purposive sampling. The best equation for estimating biomass and carbon selected using allometric equations based on the value of the highest R-Sq and practicality aspect. The results showed that allometric models for biomass and carbon wasW=3.42 DBH1.153 and C = 0.58 DBH 1,586 respectively. The potential of biomass and carbon in smallholder rubber plantations Tarean Village, District Silindak, Serdang Bedagai were 40.54 tons / ha and 20.58 tons C/ ha ,respectively.

Global warming is causing an increase in temperature of the earth's atmosphere, climate change, resulting in the dry season and rising temperatures. Efforts to control global warming is with the plant the absorption of carbon. One of which is rubber plant that has a high potential carbon reserve. The purpose of this research want to know the carbon content in each section rubber tree (Hevea brasiliensis Muell. Arg.) and determine the potential of carbon reserves in the rubber tree (Hevea brasiliensis Muell. Arg.) Age of 5 years in people plantation Serdang Bedagai. The method of estimaty carbon stocks done destructive and selection of plant samples carried out with purposive sampling. The carbon content in each section rubber trees (Hevea brasiliensis Muell. Arg.) 5 years of age is different is stem 50.37%, 40.58% branches and leaves 21.68%. The results showed that allometric models for biomass and carbon has W = 3.425 DBH1.153 and C = 0.582 DBH 1.586 , respectively. The potential of biomass and carbon in smallholder rubber plantations Tarean Village, District Silindak, Serdang Bedagai were 2.71 tons / ha and 1.18 tons C / ha, respectively.
