Abstract

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.

Abstract

The effect of reduced impact timber harvesting technique to structure and species composition of seedling and poles was studied using the data of three plots each sized 100 m x 100 m, which are placed randomly at landing, middle skiddtrail and tips of skiddtrail, respectively. The aim of the study was to know the effect of reduced impact timber harvesting technique to structure and species composition of seedling and poles in tropical forest. The research showed that the forest harvesting caused the changing of the structure and species composition of seedling and poles in natural tropical forest.

Tujuan penelitian ini adalah untuk mengetahui radiosensitivitas tanaman kedelai [Glycine max (L) Merr ] varietas Argomulyo melalui irradiasi sinar gamma dan mengetahui respon pemberian tingkat irradiasi mikro sinar gamma terhadap pertumbuhan dan perkembangan dari benih kedelai turunan pertama (M ). Penelitian ini 1merupakan percobaan faktor tunggal dosis irradiasi yang terdiri dari delapan taraf, yaitu 0 Gy, 200 Gy, 400 Gy, 600 Gy, 800 Gy, dan 1000 Gy. Untuk mendapatkan nilai Lethal Dosis 50 (LD ), digunakan program Curve-fit 50Analysis. Untuk mengetahui respon pemberian tingkat irradiasi mikro sinar gamma, benih kedelai yang diuji adalah benih kedelai varietas Argomulyo yang diirradiasi dengan dosis rendah sinar gamma (micro mutation) dengan dosis sedikit dibawah LD yaitu 0 Gy, 50 Gy, 100 Gy, 150 Gy dan 200 Gy. Hasil penelitian menunjukkan 50 bahwa nilai Lethal Dosis 50 (LD ) terdapat pada dosis 457,178 Gy. Keragaman yang diperoleh dari tinggi 50 tanaman, jumlah cabang, jumlah polong, jumlah polong hampa dan jumlah biji pada generasi M mempengaruhi 1 pertumbuhan dan perkembangan tanaman baik secara kualitatif dan kuantitatif yang akhirnya akan mempengaruhi produksi tanaman.Kata kunci: irradiasi sinar gamma, radiosensitivitas, kedelai varietas Argomulyo

Abstract

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

Abstract

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.

Abstract

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.

Abstract

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. Keywords: Karet (Hevea brasiliensis Muell. Arg), carbon stocks, biomass measurement, allometric models.

Abstract

The purpose of this study were to determine the potential of carbon on under storey level and to determine the effect of slope on a large or small carbon stocks in understorey in education forest University of North Sumatera District Karo. The research was conducted in April 2015. Data was collected by using purposive sampling with random start. Plot size is 20m x 20m as 6 plots with 3 plots in area ramps and 3 plots in steep terrain. Data were collected by destructive methods. The results showed that 14 species are found under the ramps region and 12 species on the steep region. Potential carbon found in the ramps region that is equal to       93,08 kg/ha and the potential of the carbon contained in the steep region that is equal to 83,84 kg/ha. The carbon in the ramps region is larger than in the steep region. Keywords: carbon, understorey, ramps region, steep region, education forest University of North Sumatera
