“…Several agricultural species require vernalization for production; however, this process usually occurs in plants that propagate through vegetative propagules (bulbs, shoots, tubers, or rhizomes), such as onions when propagated vegetatively (D'Aangelo;Goldman, 2018), strawberries (Buffon et al, 2021), amaryllis (Andini;Setiado;Siregar, 2019), and gladiolus (Tomiozzo et al, 2019). However, in Brazil, the vernalization process for garlic consists of applying low temperatures to seed cloves to induce bulbification (Luz et al, 2022).…”

Brazilian producers have been seeking to improve garlic productivity and quality via vernalization at negative temperatures. However, more concrete information about the application and effects of this technique on the productivity and quality of noble garlic varieties is lacking. Moreover, there are also questions about the use and influence of seed cloves at different maturation points on this crop’s yield. Therefore, the objective of this work was to evaluate the effects of vernalization temperatures and different maturation points of seed cloves on the yield and quality of noble garlic cultivars. Three experiments were conducted using the Ito cultivar over three garlic planting seasons in Cristalina, GO, Brazil. The experimental design followed a 3 x 3 factorial scheme: three vernalization temperature ranges (-1 to -3 °C; 1 to 3 °C; and 2 to 4 °C) and three seed clove maturation points (normal, early and late). Plant height, aboveground fresh mass, bulbar ratio, and bulb yield and quality were evaluated after harvesting. The negative vernalization temperature had significant results with the highest garlic yields occurring in all three planting seasons, with a considerable increase in the quantity of bulbs with better commercial value (‘class 6’) and a decrease in the quantity of ‘discard’ bulbs. In comparison to the other temperatures, negative vernalization temperatures also yielded higher fresh plants in all evaluated seasons. The normal maturation point resulted in gains in total bulb yield. The use of below-zero vernalization temperatures increased the productivity of the garlic cultivar Ito under the conditions found in Brazil.

“…Several important agricultural species need vernalization for their production. Generally, this process occurs in plants that are propagated through vegetative propagules (bulbs, corms, tubers or rhizomes) as is the case of onion when vegetatively propagated (D'Angelo and Goldman, 2018), lily (Li et al, 2016), garlic (Wu et al, 2016), amaryllis (Andini et al, 2019) and gladiolus (Tomiozzo et al, 2019). However, crops that are propagated by stolons, such as strawberry (Diel et al, 2017), and by seeds such as wheat (Shourbalal et al, 2019) and statice (Shillo, 1976) may also require vernalization.…”

Transforming a home refrigerator into a BOD prototype for statice vernalization

et al. 2021

Vernalization, natural or artificial, is a physiological requirement of some plants to meet the need for low temperatures for its complete development to occur. The objective of this article is to describe a protocol of transforming a domestic refrigerator into a BOD (Biochemical Oxygen Demand) prototype aimed at vernalizing propagating materials statice crop. The first step is to install a temperature controller to maintain a constant temperature inside the refrigerator (10 °C). Thinking of seedling vernalization, it is still necessary to install a system of lights inside the refrigerator. The control of the time that the lights remain on inside the prototype is carried out by installing a Timer adjusted so that the lights remained on, uninterruptedly, for 10 hours. To test the effective ness of the prototype, an on-farm experiment was carried out with the statice (Limonium sinuatum L.) crop at 5 locations in Rio Grande do Sul, Brazil. The seedlings were vernalized at an internal temperature of 10 °C and photoperiod of 10 hours for 3 weeks. The duration of this experiment was 8 months and at the end of this observed that statice plants were correctly vernalized because the plants emitted flower stems and showed satisfactory development throughout the growing cycle. Therefore, that the adaptation of a domestic refrigerator as a BOD economically viable and easy mounting prototype is possible. Being an excellent alternative to small producers.
