Plant Irradiation
PhotonEdit

- https://www.sciencedirect.com/science/article/abs/pii/S003375606280091X
- Plants with low chromosome numbers and large nuclear volumes more sensitive, while polypoids and plants with high chromosome number resistant. 500-fold sensitivity
- Lethal dose for Pinus strobus ~600 r
ProtonEdit
- Chonnam National University, Korea
- Cowpea legume irradiated to 100 Gy, 200 Gy, 300 Gy, 400 Gy and 500 Gy of Cobalt gamma rays and proton 57 MeV
- 2021 -- A Comparison of the Transcriptomes of Cowpeas in Response to Two Different Ionizing Radiations" (Kang R, Plants, 2021;10(3):567
- Differential transcription changes between photon and proton; proton significantly higher differentially expressed genes

- Lethal Dose 50 ~200-300 Gy for both proton and photon.
- Antioxidant enzymes reacted to proton beams more, chlorophyll responded more to photons

- Barley seeds irradiated with proton 3 Gy and 5 Gy, then grown in presence of NaCl (100 mM and 200 mM)
- Proton 3 Gy irradiation can alleviate harmful effects of 100 mM NaCl salinity
