“…A significant increase in germination by 38 % at the established optimal radiation dose of 250 J m -2 obtained in present study (the investigated range is 50-1000 J m -2 ) is in consistent with results observed in Rupiasih & Vidyasagar (2016), where the influence of different period of exposure (30, 60, 90, 120 and 180 minutes) using a UV-С source from Pride (240 V, 50 Hz; 20 W) on the effectiveness of wheat seeds germination has been studied. The results showed that there is no direct dependence between the exposure periods and seed germination.…”

“…Maximum germination of 96.7 % was recorded at 180 min UV-C irradiation treatment, and it was low (83.3 %) at 60 min UV-C treatment that is equal to control. At the same time, the minimum germination of 67 % was recorded at 120 min treatment (Rupiasih & Vidyasagar, 2016).…”

“…It should be noted that the effect of UV radiation on the biology of seeds and their germination is not well understood (Rupiasih & Vidyasagar, 2016). It is known, that seeds react to UV radiation, both as on wave length pre-sent in the sunlight (UV-A and UV-B), and wave length below 280 nm (UV-C).…”

An investigation of the effects of UV-C radiation from source having the power of 20 W on improvement of seed quality of Ukrainian winter wheat (Triticum aestivum L.) six cultivars: ‘Gratsіia Myronivska’, ‘Trudivnytsia Myronivska’, ‘Vezha Myronivska’, ‘Mudrist Odeska’, ‘Nyva Odeska’ and ‘Lira Odeska’, has been done. In the performed experiment the UV-C irradiation in the range of 50-1000 J m-2 was applied. Based on the experimental results it is concluded that irradiation of UV-C on wheat seeds stimulated the seed vigour and germination. It has been established the optimal irradiation dose of UV-C radiation - 250 J m-2 for ‘Trudіvnitsia Myronіvska’, ‘Mudrіst Odeska’, ‘Nyva Odeska’, ‘Lіra Odeska’ cultivars and 500 J m-2 for ‘Hratsіia Myronіvska’ and ‘Vezha Myronіvska’ cultivars, which leads to maximum effect. The highest biometric indices of seedling structural elements were obtained from the seeds of all wheat cultivars, for which the values of seed vigour and germination were also maximum ones, i.e. at the same irradiation dose.

We quantitatively evaluate the effects of UV-C radiation on bean seeds Oti (Phaseolus vulgaris), their germination and phenolic compounds of seedlings, by means of photoacoustic spectroscopy and scanning electron microscopy. It is shown that: i) The photoacoustic signal produced by the bean seeds exposed to UV-C radiation during 15 minutes, reduces from 0.24 to 0.10 mV for the wavelengths of 295 and 340 nm, as a result of their degradation. This significant reduction of 58.3% decreases, but keeps over 50% for other spectral UV wavelengths within the interval (270-400 nm). ii) As the UV-C radiation time increases from 2 to 15 min, the morphological changes at the surface of the bean seeds exhibits micro-holes and detachment of the cotyledon sclereids. iii) There are no significant statistical differences in the variables of germination, dry weight and seedling length, for exposure times up to 15 minutes. iv). The phenolic acids and flavonoids of the bean seedlings of seeds treated by UV-C for different exposure times (0, 2, 5, 10 and 15 min) display significant statistical differences (P ≤ 0.05) in both roots and foliage. For both the roots and foliage, the highest concentration of phenolic acids is observed at 10 and 15 minutes, while for root flavonoids, it appears at 5 and 15 minutes.

“…Adriano, S., dkk. 2014 telah melaporkan bahwa biji tanaman tomat yang diradiasi UVC selama 60-120 menit (dosis tinggi) mengakibatkan kerusakan pada tingkat fisiologi dan morfologi tanaman tomat, khususnya pada daun dan tunas dapat menyebabkan kematian tanaman [2][3] [4]. Peneliti lain juga melaporkan bahwa semakin lama biji cabai rawit diradiasi UVC, maka dapat mempengaruhi kerapatan stomata, kadar klorofil dan kadar kapsaisin dari buah yang dihasilkan [5].…”

Telah dilakukan penelitian tentang pengaruh mikrogravitasi pada biji cabai rawit (Capsicum frutescent L.) yang telah terpapar radiasi UVC selama 1 jam terhadap laju pertumbuhan dan persentase hidup tanaman cabai. Lingkungan mikrogravitasi disimulasikan menggunakan klinostat 2-D dengan kecepatan rotasi 2,7 rpm. Biji terpapar radiasi UVC tersebut diberikan perlakuan mikrogravitasi selama 12 jam, 24 jam, dan 48 jam, yang secara berurutan disebut sampel S5, S6, dan S7. Sebagai pembanding adalah biji tanpa perlakuan (kontrol), biji dengan radiasi UVC selama 1 jam, biji dengan perlakuan mikrogravitasi selama 12 jam, 24 jam, dan 48 jam, yang secara berurutan disebut sampel S0, S1, S2, S3, dan S4. Semua kelompok sampel tersebut ditanam pada lingkungan gravitasi normal, 1 g. Penelitian ini dilakukan selama fase vegetatif (sampai umur tanaman 40 hari). Pengukuran tinggi tanaman dan jumlah tanaman hidup dilakukan setiap hari. Hasil penelitian menunjukkan bahwa perlakuan mikrogravitasi pada biji cabai yang terpapar radiasi UVC selama 1 jam memberikan pengaruh negatif atau positif terhadap laju pertumbuhan tanaman cabai rawit. Besar pengaruh bergantung pada lama perlakuan yang diberikan dan fase pertumbuhan tanaman. Pada persentase tanaman hidup, tidak terdapat perbedaan antara sampel kontrol dan sampel dengan perlakuan mikrogravitasi.Kata Kunci : mikrogravitasi, biji cabai rawit, radiasi UVC, laju pertumbuhan, persentase tanaman hidup Abstract A research on the effect of microgravity on cayenne pepper seeds (Capsicum Frustescent L.) that has been exposed to UVC radiation for 1 h on the growth rate and the percentage of plants life has been done. The microgravity environment was simulated using a 2-D clinostat with a rotational speed of 2.7 rpm. The seeds exposed to UVC radiation were given microgravity treatments for 12 h, 24 h, and 48 h, sequentially called as samples S5, S6, and S7. As comparison, it has been prepared a group of control such as Seeds without treatment (control), Seeds with UVC radiation for 1 h, seeds with microgravity treatment for 12 h, 24 h, and 48 h, sequentially called as S0, S1, S2, S3, and S4 samples. All of the sample groups were planted in a normal gravity environment, 1 g. This study was conducted during the vegetative phase (up to 40 days of plant life). Measurement of plant height and number of life plants is done daily. The results showed that microgravity treatment on cayenne pepper seed exposed to UVC radiation for 1 h gave negative or positive effects on the growth rate of cayenne pepper plant. The effect depends on the length of the given treatment and plant growth phase. In the percentage of life plants, there was no difference between control and samples with microgravity treatment.
