“…In experiment II, the total number of fruits produced by CR and YC increased by 41% and 32%, respectively, in plants grown under L-8 compared to H-16. Furthermore, the total number of fruits produced by CR were also higher under H-12 (46) compared to L-8 (34). Similarly, the total number of fruits produced by YC plants grown under H-16 (82) were higher than those under L-12 (59).…”

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.

“…Flies in the genus Bradysia (Diptera: Sciaridae), the darkwing fungus gnats, can be severe pests of ornamental and vegetable greenhouse production systems [33, 34]. Female Bradysia impatiens are more attracted to geranium seedlings infected with several plant-pathogenic Pythium spp.…”

Attraction, Oviposition and Larval Survival of the Fungus Gnat, Lycoriella ingenua, on Fungal Species Isolated from Adults, Larvae, and Mushroom Compost

et al. 2016

We previously showed that the females of the mushroom sciarid, Lycoriella ingenua (Dufour, 1839) (Diptera: Sciaridae), one of the most severe pests of the cultivated white button mushroom, Agaricus bisporus (J.E. Lange) Emil J. Imbach (Agaricales: Agaricaceae), are attracted to the mushroom compost that mushrooms are grown on and not to the mushrooms themselves. We also showed that females are attracted to the parasitic green mold, Trichoderma aggressivum. In an attempt to identify what is in the mushroom compost that attracts female L. ingenua, we isolated several species of fungi from adult males and females, third instar larvae, and mushroom compost itself. We then analyzed the attraction of females to these substrates using a static-flow two choice olfactometer, as well as their oviposition tendencies in another type of assay under choice and no-choice conditions. We also assessed the survival of larvae to adulthood when first instar larvae were placed on each of the isolated fungal species. We found that female flies were attracted most to the mycoparasitic green mold, T. aggressivum, to Penicilium citrinum isolated from adult female bodies, and to Scatylidium thermophilium isolated from the mushroom compost. Gravid female flies laid the most eggs on T. aggressivum, Aspergillus flavus isolated from third instar larval frass, Aspergillus fumigatus isolated from adult male bodies, and on P. citrinum. This egg-laying trend remained consistent under no-choice conditions as females aged. First instar larvae developed to adulthood only on S. thermophilium and Chaetomium sp. isolated from mushroom compost, and on P. citrinum. Our results indicate that the volatiles from a suite of different fungal species act in tandem in the natural setting of mushroom compost, with some first attracting gravid female flies and then others causing them to oviposit. The ecological context of these findings is important for creating an optimal strategy for using possible semiochemicals isolated from these fungal species to better monitor and control this pestiferous mushroom fly species.

“…Sixteen uniform seedlings of all cultivars were selected to be used in each experimental run, and were planted as one seedling per 8 inch diameter (20.3 cm) 'azalea' plastic container (3.1 L) (BWI; Nash, TX, USA) and filled with the same substrate described above. A 2.5 cm layer of parboiled rice hulls (Sungro; Agawam, MA, USA) was applied to the substrate surface of each container to minimize complications with fungus gnats [15]. Periodical applications of biological control products such as NemaShield ® were used as preventative measures for pest control.…”

Evaluation of Compact Tomato Cultivars for Container Gardening Indoors and under Sunlight

2022

View full text Add to dashboard Cite

Numerous compact tomato cultivars are available for home gardening. However, evaluations under different environmental conditions are limited. The aim of this study was to characterize the growth and productivity of 20 compact tomato cultivars grown indoors under environmental conditions that resembled a residential space (11 mol·m−2·d−1 of white light, constant 22 °C, and moderate relative humidity) or in a greenhouse with sunlight only. Plants in the greenhouse were generally larger and yielded more fruit than those grown indoors, likely due to the various differences in environmental conditions and corresponding effects of water and nutrient availability. Considering growth and yield variables, all cultivars evaluated in this study are recommended for outdoor gardening. However, ‘Little Bing’, ‘Sweet SturdyTM F1—Grace’, ‘Sweet SturdyTM F1—Jimmy’, ‘Sweet SturdyTM F1—Jo’, and ‘Tarzan F1′ are likely too large to be grown in most space-limited indoor environments. Furthermore, ‘Little Bing’, ‘Rosy Finch’, ‘Sweet ‘n’ Neat Yellow’, and ‘Yellow Canary’ were affected by intumescence when grown indoors, which could negatively affect gardening experiences until recommendations to mitigate this disorder become available. Results from this study provide baseline information for the use of compact tomato cultivars for container gardening indoors and under sunlight.
