“…The survival rate depends on following factors: (i) method of grafting; (ii) the microclimate conditions in witch the healing is conducted; (iii) the subsequent acclimatization (hardening) process [11]. Figure 8 shows the principle of monitoring and control of microclimate factors in industrial healing or acclimatization rooms [12]. Fig.…”

“…8. Schematic diagram of environmental control system of a healing room [12] In this regard, in 1999, Chiu and collaborators [13] developed an closed automated healing room at Lan Yang Institute of Technology in Taiwan. The room dimensions were 3.52 x 1.8 x 2.1 m, where the isolating walls have a thickness of 50 mm and the internal height is 1.85 m. The transfer of heat between the inside and the outside is negligible because the room is well terminal isolated.…”

“…9. Cross section of an acclimatization chamber for grafted seedlings [14] In 2014 Dong and collaborators [12] developed an healing chamber designated to industrial production of grafted vegetable seedlings at Beijing Jing Peng International Hi-Tech Corporation. Starting from the general principle shown in Figure 7 and making the assumption that the air in the enclosure is a perfect gas, for precise and real-time control of temperature, humidity, light, CO2 concentration and other factors, it is necessary to design specific hardware and software applications.…”

“…10. Healing chamber developed in China [12] The industrial seedlings farms use advanced technologies such as controlled environment chambers for healing and growing plants, so called 'Closed-type Plant Production System' (CPPS). These concept can produce uniform plants, can reduce floor area by 90% as compared with regular greenhouse and can achieve 97% water use efficiency by recycling.…”

In the civil and industrial construction engineering, the comfort of occupants is ensured by achieving appropriate microclimate conditions. The human physical comfort (thermal, visual, acoustic) is achieved when the person from an enclosure is in a state of equilibrium and is able to perform tasks with maximum possible efficiency and without any kind of stress. Similarly, in the case of crops grown inside protected spaces, for plants, just as in the case of human being, specific microclimate conditions need to be ensured for their optimum development during the vegetation period. Plant development is a result of its own genetic features, but this is influenced by microclimate conditions inside of the greenhouses. Even more, in the case of healing and acclimatization rooms for grafted vegetables, the specific microclimate conditions must be strictly monitored. Technologically, it is recommended an optimum indoor temperature between 23°C and 25°C, with a maximum value that must not exceed 28°C, under conditions of relative humidity around 85% - 95%. Other two important aspects are the CO2 concentration and the level of solar radiation. The value of the CO2 concentration is an indicator of the healing process. For the grafting process, it is useful to know the time of the connection of the donor and receiver. Led by the the light levels, the photosynthetic activity of the grafted seedlings in the healing period, lead to a decreasing of CO2 concentration. This means that the two parts of the planting material are jointed, healed. So, the farmers can manipulate the environment in the healing rooms. This paper presents an overview of the scientific and technical issues that have to be achieved in order to reach suitable control and management of microclimate conditions in healing rooms for grafted vegetables.

“…Thus, during the first 48 h after grafting, transplants are placed at high humidity (95%) and temperature is maintained at 27-28ºC (82ºF) . The use of various types of controlled environment (temperature and humidity) healing chambers enhance the graft union success ratio by up to 95% (Dong et al, 2015), and the use of these healing champers is widely practiced in Japan, Korea, China, Spain, and USA (Kawai et al, 1996;Lee et al, 1998;. The details about the grafting methods, graft union healing and acclimatization process can be found in Bie et al (2017).…”

In Pakistan vegetables are grown on fairly a large area and help to fulfill the food requirements of increasing population. The average yield of vegetables in Pakistan is lower compared with the other vegetables growing countries; several reasons contribute towards this low yield such as biotic factors (diseases and pest attack), abiotic factors (low and high temperature stress, high light intensity, water scarcity, and salinity), seed quality, and potential of local vegetable's cultivars. Vegetable grafting is commercially practiced in more than 28 countries across the world. According to the best of our knowledge, up till now there is no research work or practical application of vegetable grafting in Pakistan. Thus in this review we have tried to highlight the importance of vegetable grafting, and how this technique can help uplift/boost up the vegetable sector of Pakistan. Additionally, a working model has been suggested for the development of vegetable grafting in the country. In Pakistan, vegetables such as cucumber, melon, watermelon, tomato, pepper, and bell pepper are sown in plastic tunnels during winter (November and December) to get off season/early produce, however, because of low temperature during the early crop growth period (November-February), a slow rate of growth is observed. Grafting of these vegetable onto selected low temperature tolerant rootstocks can enhance the growth and productivity of vegetables. On the contrary, watermelon, muskmelon, tomato and chilies cultivated under field conditions during the summer season (March-September) suffer from higher temperatures and water scarcity. The use of appropriate rootstocks can enhance the heat and drought tolerance of these vegetables. In short, grafting can be utilized to overcome a large number of problems associated with vegetable production in Pakistan such as soil borne and foliar pathogens, nematodes attack, low and high temperatures stress, salt and heavy metals stress, drought and flooding stress. Additionally, grafting can improve the yield; prolong harvesting period and postharvest life of vegetables, provided appropriate rootstocks are utilized. Grafting of vegetables ensures limited use of inputs (pesticides and fertilizers), thus protects environment, promotes organic vegetable production; and it can help to uplift the economic status of farmers of Pakistan.
