Detailed Genetic Analysis

🌾 테프(Tef) 및 열대 작물 연구 라이브러리

Tef & Tropical Plant Research Collection (TF Series)는 에티오피아의 전통 곡물인 테프(Eragrostis tef)와 고온 다습한 환경에 최적화된 열대 모델 라이브러리입니다. 전통적인 밀 모델을 개선한 TFAPS048 모델을 기반으로 하며, 글루텐 프리 식량 자원이자 기후 변화 대응 작물로서의 테프 생육을 정밀하게 분석합니다.

🔬 모델링 핵심 메커니즘

본 데이터셋은 열대 작물의 독특한 스트레스 내성과 군락 발달 특성을 모사합니다.

  • N-Wheat 기반 밀접 응용: 테프의 미세한 곡립 형성과 분얼(Tillering) 특성을 반영하기 위해 고도화된 밀 모델링 로직을 차용하였습니다.
  • 고온 및 수분 스트레스 효율: 열대 지역의 극심한 증발산량과 VPD(Vapor Pressure Deficit)가 광합성과 수확량에 미치는 영향을 수치화합니다.
  • 낮은 질소 요구도 내성: 척박한 토양에서도 생존 가능한 테프의 효율적인 질소 활용 능력을 파라미터화하여 저투입 농법 시뮬레이션을 지원합니다.

🌍 사회 및 경제적 가치

  • 식량 안보 및 고대 작물 복원: 아프리카 뿔 지역의 주식인 테프의 생산량 예측을 통해 국제 식량 원조 및 공급망 관리에 기여합니다.
  • 글루텐 프리 시장 분석: 전 세계적으로 수요가 급증하는 테프 품종의 위도별 적응성을 평가하여 신규 재배지 확장을 돕습니다.

GTMAX -50. 30. 40. 60. !Tmax thersholds used for effect of grain number; maximum temeprature values used for interpolation of effects GRDUH 0. 0. 0. 0. !Tmax effect on grain number; to TURN-ON set values to 0. 0. -50. -50. and to TURN-OFF set all values to zero GTMIN -50. -1. 2. 50. !Tmin thresholds used for effect of grain number GRDUL 0. 0. 0. 0. !Tmin effect for grain number; to TURN-ON set values to -50. -50. 0. 0. and to TURN-OFF set all values to zero DTTPT 20. 80. 120. !Sum of thermal temepratures (DTT) point to set up DTT factor of Temperature effect of the Grain #; DTT are from end of ear development. DTTF 0. 0. 0. !DTT factor as function of DTT points; to turn-on set values to 0. 1. 0. and to turn-off set all values to zero !Note GRDUH,GRDUL and DTTF should be turned-on and turned-off together to get the effect of temperature on grain number VPD 0. 1. 7. 8. !vapor pressure deficit used in canopy temperature effect, VPD values of refernce for interpolation VPDF 0. 0.3 1. 1. !vapor pressure deficit effect used in canopy temperature effect;these are values used to modify the effect of VPD on canop temeprature effect ! To turn-on VPDF, set values to 0., .3, 1., 1.,and to turn-off, set all values to 0. ! when we set values of vpdf to 0, then canopy temperature is equal to the maximum air temperature and hence there will be no cooling effect ! To see the effect of canopy temeprature with out vpdf effect, set the values of vpdf all to 1. TCSLP -12.0 !Canopy temperature modification slope; to turn-off just comment on this line and to turn-on remove the comment ! TCSLP 0.0 !Turn off Canopy temperature modification slope; when TCSLP is turn-on comment this line and when TCSLP is turn-off, remove the comment from this line TCINT 6.0 !Canopy temperature modification intercept; To turn-off, comment this line and to turn-on remove comment from this line ! TCINT 0.0 !Turn off Canopy temperature modification intercept; no comment on this line means the TCINT is turn-on and visa-vis TTHLD -50.0 ! Minimum temperature (Tmin) threshold for frost effect (frost effect starts when Tmin<-5) ! To turn-on frost effect set the TTHLD to -5 or below -5 depending on your Tmin threshold you are interested in to see the effect ! To tun-off frost effect, set the TTHLD to a value beyond the range of minimum Tmin (e.g.-30 oC) FRSTF 0.1 !

Base temperature below which no development occurs, C CRWNT .02 ! crown temperature SNOW 0 ! Switch for snow effect of frost (0=switch off; 1=switch-on) ! Canopy temeprature effect and vpdf effect need to be turned on and off together because the purpse of vpdf is to moderate the canopy temeprature effect !!Note: for temeprature effect on leaf senescence; the orginal option is with (T, F) combinations of ((-10, 1) ; (34 , 1); (34.1, 3) and (50, 11)). ! For no heat stress on leaf scenescence, set the values of F1..F4 to 1 and to use different threshold, change T2; e.g. if we use 32 for T2 which means we set the heat stress threshold at 32 0C *PHOTOSYNTHESIS PARAMETERS PARSR 0.50 !Conversion of solar radiation to PAR CO2X 0 220 280 330 400 490 570 750 990 9999 CO2Y 0.00 0.85 0.95 1.00 1.02 1.04 1.05 1.06 1.07 1.08 !Note: Photosynthesis response to CO2 for C-4 maize, sorghum, millet is reduced from prior. !Above 2 lines re-done by K. J. Boote, based on USDA-ARS SAP4.3, 2008, see Tables 2.6 and 2.7 !and cited references, summarizing a 4% grain yield/biomass increase for doubling of CO2. !Maize model now gives 4.59 & 4.24% grain yield increase from 330-660 or 350-700, respectively, and !1.17% from 380 to 440 (SAP4.3 cites 1%). Biomass increase is 3.23 & 2.93%, respectively & 0.88%. !Sensitivity for 5 irrigated/non-stressed maize experiments (UFGA, FLSC, IBWA, SIAZ, and IUAF). !The ET is reduced 12.74 & 13.50% from 330 to 660, and T reduced 17.08 & 18.12% from 350 to 700ppm. !Function based on stomatal resistance method of Allen et al. CO2 effect on ET and T are good and !did not need to be changed. *APCO2 APSIM CO2 PARAMETERS TEFAC 1 ! Switch for transpiration effect coeff; turn-on = 1 and turn-off = 0 ! Use turn-on for all simulations RUEFAC 0 ! switch for RUE Factor; turn-on = 1 and turn off = 0 !Use turn-on for all simulations !Note: the above switch for TEFAC and RUEFAC mean that 1 is switch on and 0 is swich off. !When we switch-off the effect of CO2 it means that the TEFAC (transp_eff_coeff) will set to a value of 0.006 and RUE (rue_factor) to 1 *STRESS RESPONSE FSLFW 0.050 !Fraction of leaf area senesced under 100% water stress, 1/day FSLFN 0.050 !Fraction of leaf area senesced under 100% nitrogen stress, 1/day FSLFP 0.050 !Fraction of leaf area senesced under 100% phosphorus stress, 1/day *SEED GROWTH PARAMETERS !
