“…The competition between the bud germination and the fruit growth with temperatures above 25°C might depress the standardized fruit growth rate. The reduced fruit growth with temperatures above 25°C was reported for not only Satsuma mandarin, but also other fruits such as Japanese pear (Pyrus pyrifolia Nakai) (Sugiura et al, 1995) and tomato (Adams et al, 2001;Wada et al, 2013). Additionally, in Satsuma mandarin, CiFT, a citrus ortholog of Arabidopsis FT which is involved in flowering, was hardly expressed in the stem at 25°C (Nishikawa et al, 2007) and summer season (Nishikawa et al, 2009).…”

In this study, we discussed how temperature and other environmental factors affect the fruit growth and quality of Satsuma mandarin grown in a plastic house with heating. At 14 23°C, the average nighttime air temperature was positively correlated with the standardized fruit growth rate (GRFSt) in the young stage. In contrast, GRFSt was clearly depressed with a daytime air temperature at around 30°C, and the optimum air temperature for active fruit growth was 25°C. Moreover, in the middle and mature stages, the air temperature did not correlate with the GRFSt. These results indicate that, in the young stage, the air temperature should be controlled at around 25°C during the daytime and 20 23°C during the nighttime for active fruit growth. In the middle and mature stages, fruit growth might not require nighttime air temperatures that are as high as 20 23°C. The air temperatures did not correlate with the fruit soluble sugar content (SSC); in contrast, a close relationship was found between the predawn xylem water potential (Xy) and SSC. The day temperature, radiation and Xy were linearly correlated with the fruit titratable acidity (TA) in the young stage.

“…Various studies have explored methods to counteract high temperatures in greenhouse cultivation; such methods include ventilation (Ide et al, 2007), shading (Wada et al, 2006(Wada et al, , 2013, heat pumps (Kawasaki and Ahn, 2015;Kawashima et al, 2011), and fog cooling (Hiei et al, 2015). Covering materials are also useful for reducing solar radiation inside a greenhouse.…”

The Effect of Greenhouse Cultivation Under a Heat Insulation Film Covering on Tomato Growth, Yield, and Fruit Quality in a Subtropical Area

et al. 2021

The growth and yield of tomatoes in greenhouses covered by heat insulation film were investigated in Ishigaki, a subtropical area of Japan with high temperature and high solar radiation. High-density planting of tomatoes was carried out in June, July, August, October, and November, with a low node-order pinching system. The plants were grown in two greenhouses, one covered by a thermal barrier film (TBF) for heat insulation and the other covered by a polyolefin film (PO). Under TBF, the maximum temperature was up to 3.6°C lower than that under PO, and the mean temperature was 0.4°C lower. The leaf area index (LAI) of the June planting was 3.0 under TBF and 3.4 under PO, significantly lower than the LAIs of the other plantings, which ranged from 3.9 to 5.4. The specific leaf area (SLA) varied with the cultivation season, with that under TBF and PO being highest in November plantings grown in winter. SLA under TBF was higher than that under PO in the same cultivation seasons. The amount of total aboveground dry matter was significantly lower in the June planting under TBF and showed no difference in other plantings. Distribution to fruit was higher under TBF than under PO, especially in summer cultivation. The yields under TBF were significantly higher than those under PO in the July planting, and the yields under PO were significantly higher in the November planting. Under TBF, the rate of fruit cracking was reduced in the June, July, and August plantings. Under TBF and PO, plantings in October and November produced puffy fruits. The light use efficiency under TBF was higher than that under PO in the same cultivation seasons, apart from the June planting. Tomato cultivation under TBF reduced the damage from intense solar radiation during summer. TBF enabled penetration of sufficient solar radiation to distribute photosynthates to each part of the plant because of a limited sink and abundant solar radiation in a subtropical summer. These results indicate that TBF and sink-limited cultivation are effective systems for use in the high temperature and high solar radiation environments of tropical and subtropical regions. Key Words: leaf area index (LAI), light use efficiency (LUE), low node-order pinching and high-density planting, partition rate, plant factory.

“…Similarly, cooling with mist is not expected to be sufficiently effective because of restricted water evaporation at high humidity. The use of shielding material should reduce the rise in temperature due to heat from sunlight, as it decreases the heat energy that enters the house from sunlight (Wada et al, 2013). However, it is possible that blocking sunlight will reduce the light required for plant growth, resulting in poor plant growth (Hamamoto et al, 2000).…”

This study aimed to construct a cultivation simulator of high-quality tomato cultivation in hot and humid areas. In particular, the heat-shielding film characteristics and fruit cracking specific to high temperatures and humidity were modeled. The results of yield simulations based on meteorological data were compared with the results of cultivation test.As a result, these were almost in agreement with the cultivation results, suggesting the effectiveness of the simulation considering the characteristics of the film and the fruit cracking rate.
