Abstract

The effects of alternating temperature regimes on the growth and development of tomato (Lycopersicon esculentum) cultivar ‘Counter’ were investigated in a glasshouse experiment. The plants received low- and high-temperature regimes alternating every 3, 6 or 12 days. During each cycle of 6, 12 and 24 days, respectively, the temperature sum was the same as that for a control kept constant at a moderate temperature. Two temperature amplitudes (difference between high and low temperature level), viz. 3 and 6°C were applied. Only the combination of 6°C amplitude and 24-day cycle was excluded. The treatments started 10 days before (young plants) or 10 days after (old plants) anthesis of the first truss. The experiment was carried out in spring.

The development rate was dependent on the actual temperature. The developmental stage achieved depended on the temperature sum received, only temperature alternation with a 6°C amplitude inhibited development of the young plants slightly. Also the plant length increase was reduced only for the young plants at the 6°C temperature amplitude treatments. For the old plants, none of the treatments reduced growth (fresh weight increase). With the young plant, only a 6°C temperature amplitude combined with a 12-day integration period reduced total growth with respect to the control.

Tomato proved to have a great ability to integrate (compensate within a certain period) temperature. Because it results in a greater flexibility in control priorities, this ability is an important means to optimize other growth factors of the glasshouse environment and to use energy more efficiently.

A novel forecast scenario-based robust energy management method for integrated rural energy systems with greenhouses
2023, Applied Energy
Traditional energy supplies in rural areas are mainly rural power grids and fossil energy, which makes energy use inefficient and is not environmentally unfriendly. With the development of agricultural intelligence and the increasing seriousness of environmental problems, rural areas urgently need to make full use of the rich local renewable resources such as biogas and wind power. Meanwhile, it is also necessary to jointly optimize the supply of electricity and heat energy to improve energy utilization efficiency and reduce emissions. In this paper, a cooperative operation framework of the integrated rural energy system with greenhouses (IRES-GH) is introduced and a novel forecast scenario-based robust energy management method is presented to hedge the uncertainty of electric load and wind power output. Based on the forecast bounds of uncertain variables, a two-stage robust optimization (TSRO) model of the IRES-GH is first built. Using the TSRO model, the operation status of the units and energy storage elements in the worst-case scenario can be got. Then, the deterministic dispatch model is constructed based on the obtained operation status of devices and the day-ahead hourly point forecast scenario of uncertain variables to enhance the economy of the dispatch results. Since the second stage of the TSRO model includes binary variables, the nested column and constraint generation (NC&CG) algorithm is used to solve it. The effectiveness of the model and solution method is verified by two cases with different scales.
Effects of gravel mulch on surface energy balance and soil thermal regime in an unheated plastic greenhouse

On the daily scale, Ta was similar in NM and GM (section 3.1.2.3). Hence, the greenhouse air temperature regime might be considered similar for the NM and GM systems regarding vegetable growth, as most growth processes respond to the long-term integration of air temperature (De Koning, 1990). Lower air temperatures at night in the GM soil system were compensated by higher air temperatures at daytime, when crop photosynthesis occur.
This work analyses how a mulch layer of mostly gravel particles affected the soil thermal dynamics in an unheated plastic greenhouse in a Mediterranean area (South-East Spain), where suboptimal regimes of soil temperature usually prevail in winter crop cycles. Soil temperature and heat flux profiles were measured in two soil types: (i) a 0.1-m thick gravel mulch (GM) placed at the top of a 0.30-m layer of imported loamy soil and (ii) the latter without gravel mulch (NM). These measurements were conducted during a winter period (14–28 January) when the dominant source of energy in the soil root-zone was the heat from deeper soil layers. The higher albedo of the GM and its higher long-wave radiation losses reduced substantially the daily net radiation at the mulch surface by ca. 77% with respect to NM. However, the soil root-zone maintained warmer under the GM than with NM in a period when soil temperatures are usually below the optimum. This was mainly caused by the insulating property of the mulch, which acted as heat barrier and increased the resistance to heat transmission from deep soil horizons towards the surface. This passive heating of the soil root-zone by using a gravel mulch was later confirmed in a summer–winter cycle of sweet pepper grown in an unheated plastic greenhouse. The gravel mulch also reduced the soil evaporation and increased the reflected short-wave radiation towards the plants, but the air temperature above the mulch fluctuated more strongly than in the absence of the mulch.
Solar radiation threshold and growth of mini tomato plants in mild autumn/winter condition

Additionally, no low temperature typical damage to the plants was observed. Several authors (Adams et al., 2001; Heuvelink, 1995; de Koning, 1990) described the damages caused by low and high temperature for long periods, highlighting negative effects with regard to fruit setting, growth, development and quality. However, no reference was made to the occurrence of damage to vegetative parts of plants.
The value 8.46 MJ m⁻² d⁻¹ is generally indicated as the radiation threshold for vegetable crops in tropical and subtropical climates. However, several studies indicate that mini tomato plants can be cultivated in greenhouse under lower solar radiation conditions. Therefore, the establishment of the actual radiation threshold for this group of tomatoes is necessary. The objective of this study was to define the relative influence of solar radiation and temperature on plant growth, and determine the lowest value of incoming global solar radiation inside the greenhouse by which there is a significant plant dry matter accumulation in the mild autumn/winter of southern Brazil. Mini tomato plants of hybrids Cherry Wanda^® and Grape Dolcetto^® were grown in NFT hydroponic system. Nineteen plant samples were collected periodically to obtain plant dry matter, leaf area, number of leaves, plant height and absolute and relative growth rates. The variables were related to the data of incoming global solar radiation and temperature inside the greenhouse. The results were submitted to analyses of variance, regression and clustering test. Cherry and Grape plants presented similar responses to the variation of solar radiation and temperature. However, Cherry plants presented greater leaf area and growth under these conditions. Temperature had an indirect influence on plant growth, while incoming solar radiation presented a direct influence on all evaluated variables. The solar radiation threshold for both cultivars of mini tomato was 3.63 MJ m⁻² d⁻¹.
Growing fresh food on future space missions: Environmental conditions and crop management

From an energetic point of view it is more profitable to maintain higher temperatures during lighting and lower temperatures during darkness in the MTF in Antarctica because the lamps will provide heat. As crops react on an average temperature (so called ‘temperature integration’, de Koning et al., 1990), a temperature regime of 23/17° (with an average of 20 °C, like 21/19 °C) will be energetically beneficial. The production of lettuce was very high at 118 k m2 yr−1 (25 kg m2 11 weeks−1 in the experiment; Table 7) compared to commercial cultivation without supplemental lighting (35 kg m2 yr−1) observed in The Netherlands (Anon., 2012).
This paper deals with vegetable cultivation that could be faced in a space mission. This paper focusses on optimization, light, temperature and the harvesting process, while other factors concerning cultivation in space missions, i.e. gravity, radiation, were not addressed. It describes the work done in preparation of the deployment of a mobile test facility for vegetable production of fresh food at the Neumayer III Antarctic research station. A selection of vegetable crops was grown under varying light and temperature conditions to quantify crop yield response to climate factors that determine resource requirement of the production system. Crops were grown at 21 °C or 25 °C under light treatments varying from 200 to 600 μmol m⁻²  s⁻¹ and simulated the dusk and dawn light spectrum. Fresh food biomass was harvested as spread harvesting (lettuce), before and after regrowth (herbs) and at the end of cultivation.
Lettuce and red mustard responded well to increasing light intensities, by 35–90% with increasing light from 200 to 600 μmol m⁻² s⁻¹, while the other crops responded more variably. However, the quality of the leafy greens often deteriorated at higher light intensities. The fruit biomass of both determinate tomato and cucumber increased by 8–15% from 300 to 600 μmol m⁻² s⁻¹. With the increase in biomass, the number of tomato fruits also increased, while the number of cucumber fruits decreased, resulting in heavier individual fruits. Increasing the temperature had varied effects on production. While in some cases the production increased, regrowth of herbs often lagged behind in the 25 °C treatment. In terms of fresh food production, the most can be expected from lettuce, cucumber, radish, then tomato, although the 2 fruit vegetables require a considerable amount of crop management. Spread harvesting had a large influence on the amount of harvested biomass per unit area. In particular, yield of the 3 lettuce cultivars and spinach was ca. 400% than single harvesting. Increasing plant density and applying spread harvesting increased fresh food production. This information will be the basis for determining crop growth recipes and management to maximize the amount of fresh food available, in view of the constraints of space and energy requirement of such a production system.
Accumulation and remobilisation of sugar and starch in the leaves of young tomato plants in response to temperature

Delayed plant growth is then compensated for by higher temperature under conditions requiring little or no heat demand, such as when the wind speed is low, the outside temperature is high or solar radiation is high (Bailey, 1985; Körner and Van Straten, 2008). The possibility to exploit such temperature integration systems has been published for several ornamental plants and vegetable crops, such as roses (Buwalda et al., 1999), chrysanthemum (Körner and Challa, 2004), cucumber (Slack and Hand, 1983), sweet pepper (Bakker and van Uffelen, 1988) and tomato (De Koning, 1990). These strategies, which are based on a combination of models and empirical knowledge, usually use fixed time periods for achieving a certain average temperature independent of all other micrometeorological variables.
Temperature integration strategies are a method for decreasing the amount of energy consumed in greenhouse plant production. These strategies are based on the hypothesis that plants can accumulate carbohydrates such as soluble sugars and starch during periods when growth is limited by low temperature for later use when the temperature rises. However, little is known about the storage capacity of non-structural carbohydrates in plants. Therefore, three experiments with tomato plants were carried out in growth chambers where the temperature was changed from warm (dark: 24 °C, light: 26 °C) to cool (dark: 14 °C, light: 16 °C) or from cool to warm. Leaf dry matter content and leaf sugar and starch concentrations were significantly higher when plants were grown at a low rather than at high temperature. Soluble sugar and starch concentrations in the leaves increased or decreased immediately after the temperature was reduced or raised. A strong gradient of changes was observed for up to 36 h and 60 h in soluble sugars and starch, respectively. Over the next four days, sugar concentrations remained in the range observed at 36 hpost temperature change; the starch concentration continued to increase or decrease slightly. The time courses of dry matter content corresponded to those of sugar and starch concentrations. Data indicates that young tomato plants can accumulate and store carbohydrates in the form of soluble sugars and starch for at least one week when growth is limited by low temperatures. They can remobilise these carbohydrates when growth is forced again by high temperatures.
