“…Additionally, vegetable producers are often unable to transplant seedlings during the scheduled time due to various reasons, e.g., adverse weather, lack of proper equipment, problems with labor force. The solution to this problem would be a meticulously designed plant storage system [8]. Therefore, the question is whether seedlings can be transported and/or stored with the use of a system-that is designed to maintain the proper storage conditions and simultaneously do not require a large energy input to function.…”

In broccoli production a big challenge is preparation of seedlings, which must be delivered during a strictly defined period to vegetable producers that are often in distant places. The goal of the present study was to investigate the response of 5-week old broccoli transplants cv. Parthenon F1 to 2 and 6 weeks of storage at 4 °C under two LED light spectra (L1: 29% red 660 nm + 14% red 630 nm + 42% blue 250 nm + 15% green 520 nm and L2: 38% red 660 nm + 18% red 630 nm +26% blue 450 nm + 15% green 520 nm + 3% UV-A 330 nm; photoperiod 16/8 h day/night and PPFD 30 ± 10 µmol m−2 s−1) and darkness. Control 5-week-old seedlings were not stored. Light treatment improved the morphology and physiological parameters of seedlings. The yield of broccoli from control seedlings was similar to that obtained after L2 treatment, regardless of seedling storage duration. The most promising effects were obtained by adding 3% UV-A radiation to the lighting spectrum. The results are applicable to the transport of broccoli transplants to remote locations or storage for several weeks, in cases where it is necessary to delay planting.

“…Low temperature and darkness are commonly used to maintain seedling quality during short-term storage [ 19 ]. However, when seedlings are stored in the cold and darkness, photosynthesis ceases, but respiration continues; thus decreasing the dry weight and chlorophyll content of the seedlings [ 20 ].…”

Continuous darkness decreases seedling quality during storage, whereas appropriate light quality and intensity can overcome these negative effects. In this study, we determined the light intensity, storage time (ST), and storage temperature suitable for cucumber (Cucumis sativa L.) seedlings. We stored cucumber seedlings under four different photosynthetic photon flux densities (PPFDs; 0, 15, 30, and 45 μmol·m-2·s-1) at 12°C, and examined how the morphological, physiological, and photosynthetic changes in seedlings during storage affected their ability to recover after transplanting. Our results indicated that at least 15 μmol·m-2·s-1 PPFD was needed for cucumber seedlings stored in the dark for 2 or 4 d, and at least 30 μmol·m-2·s-1 PPFD was needed when the ST was extended to 6 d. Overall, our results showed that cucumber seedlings require light-emitting diode (LED) illumination during storage to maintain their quality and recovery ability.

“…However, the transplanting of plug seedlings can often be delayed due to time, equipment, labor constraints, adverse weather, and long-distance transportation. These factors can result in the overgrowth of the seedlings in trays and the loss of seedling quality [2]. Low-temperature storage in darkness is usually used to maintain quality of plug seedlings [3][4][5].…”

This experiment studied the effect of different medium moisture on plant growth, water relations, and accumulation of osmotic adjustment substances of cabbage plug seedlings during low-temperature storage in darkness and on the photosynthetic and transpiration rates after removal from storage and transplanting. The plants were not watered from 0 (control), 1 (D), and 2 (DD) d before the start of storage. The results indicated that plant growth, and leaf relative water content and leaf saturated osmotic potential under water stress treatment significantly decreased compared with the control at the end of storage. However, the water stress resulted in increase in the proline contents in leaves, and abscisic acid, soluble sugar and total ion contents in plants. Starch contents in plants decreased significantly over storage time. After removal from storage and transplanting, plug cabbage seedlings under D treatment showed a faster and steadier recovery to photosynthesis and transpiration than the control.
