Nutritional status and yield of Kinnow mandarin grafted on nine different exotic and local rootstocks was studied. Leaf nutrient status of Nitrogen (N), Phosphorous (P) and Potassium (K) availability in leaves differed significantly among the trees on various rootstocks. Maximum N (2.60 and 2.67%) was recorded on Rough lemon and minimum (2.20 and 2.21%) on Troyer citrange during 2005 and 2006 respectively. P (0.16%) was maximum on Rough lemon while minimum (0.09%) was recorded in Carrizo citrange. As regard K, it ranged from 1.15 to 1.65% on Volkamariana and Carrizo citrange rootstock, respectively. The highest number of fruits per tree were recorded on Brazillian Sour orange (1037.16 fruits) and lowest (184.49 fruits) on Carrizo citrange rootstock. While on weight basis maximum yield (139.52 kg) was recorded in Volkamariana and minimum (27.83 Kg) was in Carrizo citange. For most of the parameters Volakamariana was found to be promising followed by Rough lemon and Mithi whereas all citrange (Carrizo, Yuma and Troyer citarange) rootstocks performed poorly in relation to nutrient uptake and yield.
Effects of seven rootstocks on the performance of Citrus medica L. (‘Diamante’)
Acta Horticulturae, 2016
Citron (Citrus medica L.) has economic value in a small area in Calabria (Southern Italy). The grafting of citron on other citrus species as an alternative to C. aurantium (L.) in the Mediterranean area has not been deeply studied before. With the aim to evaluate the behavior of seven rootstocks on citron 'Diamante' performance under Mediterranean conditions, growth, yield and fruit quality were assessed during two consecutive growing seasons (2011-2012 and 2012-2013). The rootstocks studied were: i) Sour orange (C. aurantium L.), ii) 'Rubidoux' trifoliate orange [Poncirus trifoliata (L.) Raf.], iii) 'Flying Dragon' trifoliate orange [P. trifoliata (L.) Raf.], iv) 'Swingle' citrumelo [C. paradisi (Macf). × P. trifoliata (L) Raf.], v) 'Volkamer' lemon (C. volkameriana Ten. & Pasq.), vi) 'Troyer' and vii) 'Carrizo' citranges [C. sinensis (L.) Osbeck × P. trifoliata (L.) Raf.]. Trees were planted in 2008 on a deep sandy soil located in Reggio Calabria. In both years 'Volkamer' lemon, sour orange and 'Carrizo' citrange showed significantly higher yields, particularly in comparison with 'Flying Dragon' and 'Rubidoux' trifoliate orange. As far as fruit weight is concerned 'Volkamer' lemon induced the highest values. Among the studied rootstocks no relevant graft-incompatibility was recorded. The research identified some rootstocks that could be successfully introduced in the given environmental conditions. 'Flying Dragon' and 'Rubidoux' trifoliate orange, that induced a reduced plant growth, should be suitable for high density plantations, by adopting appropriate techniques to promote acceptable fruit production.
More than 20 tree characteristics are influenced by rootstock. These include tree size, cropping efficiency and fruit quality attributes such as fruit size. In Pakistan, rough lemon rootstock is used in Punjab and sour orange rootstock is used in Khyber Pakhtunkhwa. The leaf nutrient composition of three scion cultivars ('Kinnow', 'Feutrell's Early' and 'Musambi') grafted on to eight rootstocks ('Cox' mandarin, 'Cleopatra' mandarin, 'Fraser' hybrid, sour orange, Poncirus trifoliata, 'Troyer' citrange, 'Benton' citrange, 'C-35' and 'Carrizo' citrange) were tested in 3-4-year-old trees. Complementary soil analyses were also carried out across different rootstock combinations. The chemistry of irrigation water from both canal and tube well (subsoil) water sources was analysed. The results from this study indicate that scion or rootstock significantly affect leaf nutrient composition in mandarin and orange trees. Rootstock significantly influenced macro-and micronutrients, especially Na, Cl, N and B, but not Fe and Cu. The concentrations of Zn and Mn were low in many of the scion and rootstock combinations.
INFLUENCE OF DIFFERENT ROOTSTOCKS ON PHYSICO-CHEMICAL QUALITY ATTRIBUTES OF KINNOW MANDARIN
Kinnow' mandarin is considered as trademark product of Pakistan citrus industry. This distinction of Kinnow is due to its magnificent aroma, premium taste, high juice contents and nutritional profile like high vitamin C/ascorbic acid contents, rich in sugars, reducing sugars and antioxidants (Memon, 2014). Pakistan produces 2395550 tonnes of citrus annually and total area under citrus cultivation is 192832 (FAO, 2019). The significance of citrus rootstocks for the better productivity of citrus can never be neglected. It is a wellknown fact that the availability of suitable and compatible rootstocks is the key to sustained citrus industry. Fruit growers primarily focused on yield and fruit quality to determine their net income. Internal quality parameters of Kinnow such as juice content, color of flesh and peel, total soluble solids, titrable acidity, juice pH are also affected by rootstocks (Wutscher, 1997). Some rootstocks like Sour orange, Rough lemon and RLC-4 manipulated the biochemical characteristics of citrus fruits i.e. total soluble solids (TSS), titratable acidity (TA) and Vitamin C contents of lemon fruits. Differences in quality characteristics were due to different rootstocks (Yonemoto et al. 2005). Previously a lot of researchers has reported that yield and fruit quality of citrus is affected by rootstocks (Qureshi et al., 2021; Ahsen et al., 2019; Smith et al., 2004). It is very essential to understand the rootstock/scion interaction and effects of rootstocks on different scion parameters such as yield and fruit quality for making a profitable citrus fruit cultivation. Various fruit quality attributes of citrus fruits such
Effects of Citrus Rootstocks on Fruit Yield and Quality of ‘Nadorcott’ Mandarin
2020
The effects of citrus rootstocks on the performance and fruits characteristics of commercial varieties are known and well documented. These effects, as well as the resistance to biotic and abiotic stresses, constitute the main criteria that direct the rootstock choice for a new citrus orchard. The Moroccan variety 'Nadorcott' mandarin also called 'W. Murcott' and 'Afourer' is relatively new. 'Nadorcott' is a popular late mandarin cultivar, owing to its good eating quality and excellent bearing capacity. Thus, there are few undertaken research and available results related to its behavior on the widely used rootstocks in the main citrus growing areas of Morocco Kingdom. This paper presents the results of a field trial carried out in the North West Morocco, a coastal area, to evaluate the effects of five rootstocks on 'Nadorcott' yield and fruit quality: juice content, total soluble solids (TSS), acid content (A), maturity index expressed as TSS/A ratio and Citrus Color Index (CCI). The results show that the highest yields were observed on citrange C-35 and Citrus macrophylla (MAC) over the three seasons. Additionally, percentage of juice content over two successive years of fruits produced on C-35, Troyer citrange (CT), Carrizo citrange (CC) and Swingle citrumelo (SW) was about 53 % but did not exceed 50 % for Citrus macrophylla. The highest TSS was obtained on CC rootstock. However, the TSS was less than 10 in 2013 and around 11 °Brix in 2014 for Citrus macrophylla and above 12 °Brix for the other rootstocks. Regarding the maturity index, apart from the low value (11.3) scored by MAC, in 2013 due to a low TSS, there was no significant difference between the maturity indices of the fruits of the mandarin 'Nadorcott' produced on the different rootstocks tested. Furthermore, the five rootstocks had no effect on the fruit color parameters of 'Nadorcott' mandarin.

Performance of Musambi Sweet Orange on Rough Lemon and Volkameriana Rootstocks at Sargodha, Pakistan
World Journal of Biology and Biotechnology
Musambi (Citrussinensis) is the commercial variety of the sweet oranges group well flourishing inPakistan. Formany years Musambi has beenon the way of rapid decline with reduced life span besides drastic reduction in yield and fruit quality grafted on rough lemon rootstock. To overcome this problem, Volkameriana as an alternative rootstock to rough lemon was tested with the focus to find out more compatible rootstock to prevent mentioned issues. Observations on different plant growth parameters such as plant height, stock and scion circumference, canopy volume, plant fruit yield and important quality characteristics of fruit were made. The rough lemon depicted statistically significant result in plant height, spread and canopy volume in responses recorded for 10 years consecutively from 2008 to 2017. The degree of compatibility in both rootstocks in the year 2008 to 2009 were statistically non-significant. The yield was measured in terms of average No. of fruits per plant depicted t...
Studies on growth, rooting and budding performance of citrus rootstock seedlings
and Rough lemon were sown in protrays and later transplanted in poly-bags under protected conditions. The results of the experiment revealed that maximum plant height and stem thickness were recorded in C-35 citrange and Swingle citrumelo, respectively. The number of leaves/plant was highest in X-639. Volkameriana lemon and Benton citrange had the longest and thickest roots at the buddable stage, respectively. Fresh and dry root weight was maximum in Rangpur lime rootstock. Kinnow mandarin (Citrus reticulata Blanco) was budded on all the rootstocks under study and the highest budding success was recorded in Rough lemon, followed by Volkameriana lemon, Rangpur lime and Kuharsuke citrange. It was concluded that Volkameriana lemon, Kuharsuke citrange and Rangpur lime can also be explored as potential rootstocks along with Rough lemon for raising the nursery of Kinnow mandarin under protected conditions in Punjab. However, their long-term effects on fruit yield and quality, as well as stionic compatibility, should be carefully considered before making any commercial recommendations.
Incompatibility Selected Dwarf Rootstock and Scion of Citrus sp. regard to Abiotic Stress Tolerant
AGRIVITA Journal of Agricultural Science
This study aims to determine the response's incompatibility of selected dwarf citrus rootstock after treated by abiotic stresses such as drought, waterlogging, and acidity on a scion. The results of this study was selected seedlings for sub-optimal lands in Indonesia with dwarf growth characteristic and compatible with the grafted-scion. The preliminary study has shown that there were 3 (three) selected rootstock accessions with dwarf characteristics, namely Citromello (Cit), Volkameriana (Volk), and Cleopatra Mandarin (CM). The seeds of these accessions were treated with 8% Polyethylene Glycol (PEG), 150% FC; 9 mM Al 2 SO 4 at eight months after planting. Each rootstock was grafted with Pontianak orange (C. nobilis var. microcarpa). The results showed that Citromello (Cit) and Volkameriana (Volk) are incompatible rootstock and dwarf potential seedling. However, Cleopatra Mandarin has a compatibility with the grafted scion and is tolerant of abiotic stress treatments. The effect of abiotic treatment on Citromello resulted in 15% higher root length higher than other accessions. Furthermore, this variety has 40% dry weight and 25% lateral root numbers, respectively, by Al 2 SO 4 and PEG. Meanwhile, Volkameriana had the 40% higher number of leaves.
