“…From the description above, based on the determination of calculations I and II of the germination of seeds that are not exposed to the sun, although they germinate but produce low-grade and abnormal seeds. According to [10], Thuja occidentalis seeds exposed to radiation have better germination power than seeds not exposed to radiation. Large seeds in all positions in the mother plant have a high percentage of daily sprouts compared to small seeds.…”

Cloves are commonly propagated generatively using true seed. One of the factors causing the lack of qualified clove seeds is farmers^ low awareness of using high-quality seeds. Farmers usually do not produce seeds- in particular, they obtain seeds from their trees without exclusively separating trees for making seeds and flowers. The seeds are randomly harvested from all the flowers without considering the pod position and size. This study aimed to evaluate the effect of pod position and size on clove seed viability. The research was conducted at the Glass House of Indonesian Spices and Medicinal Crops Research Institute, Indonesia, from August to December 2018. The study was arranged in a completely randomized design with two factors. The first factor was the seed size: large (≥ 0.9 g) and small (< 0.9 g). The second factor was pod position : (a) the pods exposed to the morning sun, (b) the pods exposed to the afternoon sun, and (c) the pods’ unexposed sun (hidden). The pods originated from selected mother trees from Kayu Aro, West Sumatra. The results showed that seed size ≥ 0.9 g and pods exposed to the morning sun had higher viability, as indicated by the high seed growth rate, vigor, and better plant growth than other treatments.

“…[11] used ultraviolet light to irradiate spruce seeds, and this gave positive results. To control the dose of ultraviolet radiation, they developed an automated microprocessor system [12]. Kondrateva N. P., Kasatkina N. I., Kuryleva A [9] showed a positive effect of ultraviolet irradiation on the awakening of grain seeds.…”

The paper shows the synergistic effect of simultaneous exposure to ultraviolet radiation and electron-donor solution on the seed germination of grain crops. When the seed is moistened, the biochemical processes that control the growth of the root system and stem are activated in them. The purpose of the study is to determine the presence of a synergistic effect on seed germination of grain crops with simultaneous exposure to ultraviolet radiation and electron-donor solution. It was found out that the oxidation-reduction potential (ORP) is affected by the time of seed soaking, the weight of seeds and the type of grain crops. The best soaking time turned out to be 18 hours, the greatest negative ORP was in oat seeds -510 mV (100%), in barley and rye it was 487mV (95%), in wheat - 462 mV (91%). The greatest synergistic effect was obtained with a 10-minute exposure to UV irradiation of seeds at a dose of 1,882 ± 14.1 J/m2, followed by soaking in an electron-donor solution. In this case, the height of the sprouts was 108.8 mm (100%). At an exposure of 15 min (UV radiation dose 2.813 ±18.3 J/m2), the effect was slightly lower. The height of the sprouts was 107.6 mm (98.9%)

“…During the previous two decades, a considerable number of experimental papers have been devoted to the study of biological effects and mechanisms of UV radiation influence on plants (Semenov et al, 2017;Kondrateva et al, 2019;Pournavab et al, 2019). There are three potential targets for UV radiation in plant cells: genetic system, photosynthetic system, and membrane lipids.…”

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.
