“…However, this observation does not correspond with the data collected based on the subjective visual scale used in our study. Given the large variability observed in intumescence among cultivars grown in this and other studies conducted by our group [11], we believe that rating scales should be adjusted to enable the proper characterization and quantification of various symptoms. For example, intumescence injury in tomatoes can include canker-like lesions on stems and the adaxial and abaxial surface of leaves, leaf-edge discoloration, and partial or complete leaf abscission (Figure 1).…”

“…However, providing higher DLIs to achieve compact growth might not be a suitable approach for most growers unless significant increases in yield can be achieved, considering the high energy costs of providing sole-source lighting. Selecting cultivars that are compact and high yielding is a more suitable strategy for the commercial industry compared to producing plants under higher DLIs [11,14]. Using LED fixtures with high red:far-red ratios could also help maintain plants compact [42].…”

“…Tomato (Solanum lycopersicum L.) is the second most-consumed vegetable in the United States (U.S.) and the most popular gardening vegetable, cultivated in 86% of residential food gardens [9,10]. Numerous new compact cultivars are available from seed distributors that cater to home gardeners [11][12][13].…”

Our objective was to characterize the growth, physiological responses, fruit yield, and quality of tomato (Solanum lycopersicum L.) plants grown under different daily light integrals (DLIs) and photoperiods. In experiment I, nine compact tomato cultivars were grown indoors using broadband white light-emitting diode (LED) fixtures. Plants were grown under low (10.4 mol·m−2·d−1) and high (18.4 mol·m−2·d−1) DLIs with 12 and 16 h photoperiods, respectively, and two intermediate DLIs of 13.8 mol·m−2·d−1 with either 12 or 16 h photoperiods. In experiment II, three compact tomato cultivars were grown under the same low DLI with either 8 or 12 h photoperiods, and the same high DLI with either 12 or 16 h photoperiods. Generally, higher DLIs decreased plant growth and increased the fruit yield. Changing the DLI delivery strategy by adjusting the photoperiod and photosynthetic photon flux density (PPFD) did not have major effects on the growth, yield, and fruit quality of the compact tomato plants evaluated in this study, even though net photosynthesis increased under higher PPFDs in experiment II. Although several cultivars were affected by intumescence, only two cultivars showed treatment responses, for which the severity was generally higher in lower PPFDs using the same DLI.

“…Among indoor crops, tomato ( Solanum lycopersicum L.) is one of the top crops because of its remarkable nutritional and commercial aspects [ [59] , [60] , [61] ]. Regarding the volatile profile, tomato plants have been investigated under conventional and stressed conditions to determine BVOC variations between constitutive and induced emissions [ 62 , 63 ].…”

Intumescence is a physiological disorder that affects some tomato (Solanum lycopersicum) cultivars grown in environments lacking ultraviolet radiation. Both far-red (FR) radiation and blue light have been shown to help mitigate this disorder. Thus, the objectives of this study were to characterize and compare intumescence injury and growth of various tomato cultivars propagated under different radiation qualities (Expt. 1) and to evaluate plant responses to the interactive effect of radiation quality and relative humidity (RH) (Expt. 2). Seedlings of six cultivars in Expt. 1 were grown under broad band white light (W), W and blue with (WBFR) or without (WB) FR radiation, and blue and red light with FR radiation (BRFR). Seedlings of four cultivars in Expt. 2 were grown under W or WBFR and a low (≈50%) or high (≈95%) RH. In both experiments, seedlings were grown under a daily light integral of ≈13 mol·m‒2·d‒1 (200 ± 4 μmol·m‒2·s‒1 for 18 h·d−1). FR radiation was provided using 20 ± 2 μmol·m−2·s−1 delivered throughout the entire photoperiod or at the end-of-day (EOD) in Expts. 1 or 2, respectively. Intumescence was generally suppressed when seedlings in Expt. 1 were grown under BRFR and WBFR, which also corresponded with the general response to stomatal conductance (gs). In contrast, seedlings grown under W had the highest incidence of intumescence, ranging from 23% to 69% across cultivars. The high blue photon flux (PF) ratio in WB was not effective at suppressing intumescence injury without FR radiation, although incidence and severity were lower compared with W. In Expt. 2, intumescence incidence was generally lower in seedlings grown under WBFR, and RH had small effects on intumescence. In both experiments, younger leaves were relatively less affected by intumescence, suggesting that a developmental factor is associated with the disorder. As expected, providing FR radiation resulted in a general increase in stem height across cultivars and in both experiments. The high RH provided in Expt. 2 also resulted in an increase in stem height. However, seedlings under low RH produced larger leaves, lower specific leaf area, and more shoot dry mass than those under high RH. Overall, our findings show that applying FR radiation helps suppress intumescence, but strategies are needed to minimize issues with excessive stem elongation.
