Grapevine is an economic plant in several countries in the world According to International Organization of wine and vine (OIV) in 2017, the total areas of grapevines planted in 44 different countries worldwide are around 7.5 million Australia is listed in the top 15 countries with highest grape production in the same period (Aurand, 2016) In Australia, wine grapes are the most popular compared to the rest of varieties, while Adelaide Hills is one of the largest regions for making wine in the state, where Merlot are dominant in this region In recent years, Merlot is considered as a high quality varietal wine and widely grown across the world The vineyard area of Merlot was 5000 ha, which occupied 5.4 % of the total area of vineyard in Australia (OIV, 2017) Asexual propagation has been prove that it could reproduce the highestquality plants and ensure consistency of a variety of plant or crop for sale (Benbya, 2018) Specifically, grafting method is commonly used over the years for grafting vines since it could bring many benefits, such as change in variety, pest resistance, maturity and propagation, which are helpful to reduce the cost of production and enhance the quality of vines (Richards, 2019) Glenavon Nurseries Pty Ltd is a family business producing grapevines for the Australian wine industry, locating on Adelaide, South Australia In this nursery, bentch-grafting propagation method is applied to propagate high-quality grapevine varieties before planting outside to become youngvines During the propagation and production processes, some issues might be happened, therefore, the grapevines are need to be cared and trained by adequate method The objectives of this research are: - To investigate the propagation and production method of grapevines - To recognize grapevine-related issues and make solutions download by : skknchat@gmail.com PART II LITERATURE REVIEW 2.1 Grapevine 2.1.1 Grapevine origin Grapevines are a woody-climbing plant which belongs to the botanical family Vitaceae The scientific classification of grapevine includes” Kingdom Plantae – Plants Subkingdom Tracheobionta – Vascular plants Superdivision Spermatophyta – Seed plants Division Magnoliophyta – Flowering plants Class Magnoliopsida – Dicotyledons Subclass Rosidae Order Rhamnales Family Vitaceae – Grape family Genus Vitis L – grape P Species Vitis vinifera L – wine grape P The popular seedlings of grapevine such as Vitis vinifera, Vitis labrusca, Vitis riparia, Vitis rotundifolia, Vitis arizonica, Vitis californica Most of them are used for wine production as well as making jar and grape juice Vitis vinifera is the most popular grapevine which accounts for most of total grapevine quantity worldwide This species is dividing into two main groups including white grape with no-color or pale green fruits when ripping, and red grape with red or purple ones (Ha, 2014) Merlot (Figure 2.1) is a popular red grape which has thinner skin and milder tennis Merlot was normally used as a varietal wine or in a blend In the past, download by : skknchat@gmail.com 3.3.3 Caring Irrigation Drip irrigated system was utilized for watering in young graft-vines., in particular, if there was no rain, the vines could be irrigated hours/once/day Young vines tend to dry out after planting so it was essential to provide good moisture at planting adequate soil moisture should be maintained for vines until they start to grow, therefore, frequent light watering is suitable instead of over irrigating vines Fertilizers: Soil analysis need to be taken to identify the potential nutrient deficiencies in the planting area Pre-plant phosphorus and nitrogen after ripping was applied with the concentration of 1pound per 100 square feet (Agro-liquid fertilizer) Excessive fertilizer amounts should be avoided due to the fact that fertilizer can burn or kill vines Protection Planting a windbreak or cover crop in the autumn was carried out to minimize the risk from wind Using vine-guards such as plastic, sisal, coated cardboard sleeves or milk cartons was considered to protect the vines The application of cover sprays of fungicide (Mueso) is necessary to reduce disease like downy and powdery mildew Young vines were needed to check for the presence of mites, vine moth caterpillar and light brown apple moth throughout the growing season apart from pasture pests and cutworms because they can cause serious problems in a new vineyard (Figure 3.4) 29 download by : skknchat@gmail.com Mueso(unfungi) pool Mueso liquid Soak vine in Mueso pool Figure 3.4: Application of Mueso for grapevine protection 3.3.4 Training vines Using non-stretch twine is necessary to support vines since they are trained up the wire To avoid choking the vines, the twine was attached around the fruiting wire and around the vine where shoots rise Undesirable side shoots, buds and top of the vines were removed to boost wine growth The canes were wrapped down from the permanent cordons, and they were cut to stimulate lateral shoot and spur formation when adjacent vines cordons meet (Figure 4.7) 3.3.5 Recycling Several kinds of organic wastes, such as roots, soil, branches, sticks, buds were put in paper boxes and hence taken to the farm by using tractor After that, all these wastes were crushed by machine to become fertilizer that was given 30 download by : skknchat@gmail.com back to plant By the way, the non-reuse waste, for example, plastic bags, plastic tides or gloves were selected and moved by the trunk to the government company for advanced recycling (Figure 3.5) a b Figure 3.5: Recyling of organic waste (a) and non-reuse waste (b) 31 download by : skknchat@gmail.com Cutting Grafting Propagation Callusing Wazing and planting in a nusery

DISCUSSION 4.1 Result 4.1.1 Propagating grafts Cuttings (a) (b) Figure 4.1: Grapevine sticks (a) and buds (b) Figure 4.1 shows the cuttings of grapevine obtained from cutting steps All of them were straight or slightly curved, out of small buds and mold All of them are given out dead leaves, soil and other debris beside invertebrate pests The length of sticks were around 45 cm, while the category for buds stood at cm The deep-brown color insists that they were well-matured cuttings 33 download by : skknchat@gmail.com Grafting Figure 4.2: Grapevine grafts Figure 4.2 shows the grapevine sticks chosen in three blocks at the nursery and the buds taken by other company were grafted by using Omega-star grafting machine Grafts were well matched to ensure complete healing Callusing Figure 4.3: Placing grafts in callusing room 34 download by : skknchat@gmail.com Figure 4.3 shows that the boxes containing grafted grapevines were put in callusing room with the low density to avoid high temperature and low oxygen favouring the development of pathogen There were no microbial and antibiotic contaminants, agrochemicals, dust and wind in the callusing media Callusing room was kept cleaned regularly Waxing and planting in a nursery Figure 4.4: Planting grafts in nursery This figure shows that the grafted grapevines was ready to plant in the nursery after callusing and waxing

step of preparing sites for planting grafted vines that were in nursery before It was ready for planting those vines immediately after making survey, building irrigation infrastructure, finishing weed control and cultivation Planting Figure 4.6: Planting grapevines in vineyard 36 download by : skknchat@gmail.com This figure indicates how the vines were planted in vineyard The grafted grapevines were kept standing at suitable distance and their grafts were above the surface of the soil Caring and training vines Figure 4.7: Training vines This figure presents that the vines were caring and training in order to form shape and healthy structure It is clear that the vines were healthy with vigorous root system and truck after applying appropriate fertilizers and irrigation, weed and pests control and pest The training shoots were grown above the height of fruiting wire, bent over and trained along the wire 37 download by : skknchat@gmail.com Products Figure 4.8: Complete products before selling This figure shows that the grafted vines were ready for selling in Glenavon nursery 4.2 Discussion 4.2.1 Propagating grafts and young grafted vines Firstly, the obtained grafts were fully healed, which were not able to be moderate pressure applied by the thumb Secondly, the graft union were not contaminated with both organic and inorganic substances, such as grease, callusing mix and budding tapes inside Disbudding wood were not penetrated to the pith Finally, there was no internal staining or streaking in the tissues which results in leading away from the disbudding wound It is shown that the size of trunk was between and 12 mm in diameter In addition, their forms were straight and slight curved without any broken or damaged parts Besides, the sign of diseases and pests were not appeared in the vines All of chosen vines had at least well-developed shoot with healthy buds and 38 download by : skknchat@gmail.com healthy, undamaged, evenly spaced roots Furthermore, the vines got a bright color on their surface, which was not blackened or covered in large amounts of mold They were not lacking of water that leads to shriveling Finally, there was no appearances of brown and black spotting in cross-sectional cut of the tissues of trunks, canes and roots of vines The results above have proved that the propagation and production method was applied properly and problems of growing grapevines were mitigated as much as possible 4.2.2 Advantages and disadvantages People in Glenavon Nurseries Pty Ltd have facilitated the process of my internship During that time, I always received enthusiastic help from my colleagues and teachers in breeding techniques and simultaneously was provided with all necessary documents for the content of the research topic In the first days, due to my limited knowledge and skills, I faced many difficulties while doing the assigned work and topic In addition, the differences in learning and working environment between Australia and Vietnam made it difficult for me to be adaptive, but the problems somewhat overcame after living here for a year 4.2.3 Acquiring experiences Through that one-year internship, I have learned considerable experience, gained much new particularly valuable knowledge for future work related to cultivation, specifically regarding the grafting method and producing grapevines 39 download by : skknchat@gmail.com Practicing not only helps students like us obtain practical knowledge and experience in our professional field but also is an excellent opportunity to have a realistic view of daily work in the company Additionally, it also encourages us to apply all book-learning to real work, which assists us in learning more about the profession that we oriented Along with approaching cultivation and production technology in Australia, I have been more active in developing communication and problem-solving skills as well as learning from everyone to quickly achieve goals during the internship Besides, I have also built relationships with people nearby and received numerous comments from my instructors and colleagues, thereby seeing my own limitations to get better and develop my work afterwards PART V CONCLUSION In summary, this study presented the results relevant to the set research objectives, as follows: Firstly, the propagation and production method were applied properly for growing young vines that made qualified products – vigor grafted vines for selling In addition, recycling was performed after production steps which is helpful for cost savings and environmental protection Secondly, problems negatively affecting to young vine growth were found, which includes weed and water, weeds and animals Therefore, the application of weed and pest control apart from building protecting system are needed to be concerned 40 download by : skknchat@gmail.com Although there were some difficulties relating to the limitation of knowledge and skills apart from differences of working environment, these factors did not impact strongly to the process and final result of internship In my opinion, we may apply grafting propagation and planting technique in South Australia especially Glenavon Nurseries company We may develop technology and computer management in viticulture and automatically drip system instead of traditional irrigation In fact, Vietnam is developing country and tropical weather then grafting is not necessary and they have not been anyone know which kind of variety vine is good for rootstock Production wine industrial in Vietnam is still developing In the future I believe that Vietnam will apply technology in viticulture which may reduce labor hour and save more time and achieve high production 41 download by :
