“…This would demonstrate that boron presents a certain phloematic mobility in kiwifruit, according to the conditions of this experiment. This result contrasts with studies by Papadakis et al (2004) and by Sotiropoulos et al (2004), which found an immobility of boron in the phloem of kiwifruit shoots. (BF).…”

“…Papadakis et al (2004), in a study of boron toxicity in fruit plants, mentioned that orange trees and kiwifruit are species where boron may have restricted phloematic mobility. On the other hand, Sotiropoulos et al (2004) stated that the presence of high concentrations of boron in mature leaves in comparison to young leaves is evidence of boron immobility in the phloem of kiwifruit.…”

C. Sotomayor, P. Norambuena, and R. Ruiz. 2010. Boron dynamics related to fruit growth and seed production in kiwifruit (Actinidia deliciosa, cv. Hayward). Cien. Inv. Agr. 37(1):133-141. The effect of foliar boron treatments on fruit growth and seed development in Actinidia deliciosa, cv. Hayward, was studied. The distal leaves (BH) or flowers (BF) of a shoot were sprayed with 500 mg L -1 boric acid during the flowering period. The mobility of boron from the leaves to the flowers through the phloem was determined by spraying only the leaves. From 0 to 96 h after treatment, leaves and flowers were sampled and total boron was assessed. At harvest time, fruit weight and diameter plus seed weight and number were measured for the different treatments. The weight of fruits growing from shoots with boron-treated leaves were 14.1% higher than the control, while the weight of fruits derived from boron-treated flowers was 17% higher than that of fruits from untreated flowers. Regarding fruit length, significant differences between boron treatments and the control were observed, with an 8.2% and 8.5% increase for BH and BF treatments, respectively. No significant differences were found in fruit diameter. Fruits grown from shoots with boron-treated leaves had 43% more seeds than fruit grown from untreated control shoots, while fruits resulting from boron-treated flowers had 44% more seeds. This demonstrates the positive effect of boron treatment in seed production. No differences were observed in seed weight between treatments. The correlation coefficient between seed number and fruit weight was r 2 = 0.1294 for BF, r 2 = 0.1298 for BH and r 2 =0.0002 for the control. There was no variation in non-treated leaves and flowers with respect to boron concentration for a 96 h time period. On the contrary, in sprayed leaves boron levels reached up to 16 mg kg -1 between 24 and 48 h and slightly decreased after 96 h, demonstrating the boron absorption capacity of leaves. In the flowers from the shoots with boron-treated leaves, there was a significant 14 mg kg -1 increase in boron concentration from 24 to 96 h, showing boron mobility from leaves to flowers.

“…In addition, rootstock helps the rootstock-scion combination to adapt to different abiotic factors, such as drought, flooding, salinity, mineral deficiency and toxicity, metal toxicity, heat, cold, soil temperature and oxygen, pH etc. (Papadakis et al, 2004;Colla et al, 2010;Hartmann et al, 2013;Savvas et al, 2010;Ghrab et al, 2014;Castle et al, 2016) and different biotic factors such as fungal and bacterial pathogens, virus, diseases, insects or nematodes (Mudge et al, 2009;Shokrollah et al, 2009;Roistacher et al, 2010;Louws et al, 2010;Castle et al, 2016). The choice of rootstock depends on its durability to enemies and diseases.…”

The behavior of six citrus rootstocks, Volkameriana, Citrumelo 'Swingle', Citrange 'Carrizo', Poncirus trifoliata 'Serra', Poncirus trifoliata 'Rubidoux' and Poncirus trifoliata 'Flying Dragon', in in vitro propagation was studied and compared for shoot proliferation and rooting. In addition, the genetic relationships among the rootstocks studied and other Citrus species, using the Inter-Simple Sequence Repeats (ISSR) molecular markers, were investigated. Nodal explants of three months old shoots were used in Murashige and Skoog medium supplemented with N6-benzyladenine (BA) for shoot proliferation and with naphthaleneacetic acid (NAA) for rooting. The rootstock Volkameriana showed a statistically significant higher number of shoots (1.81), shoot length (15.14 mm) and number of leaves per explant (5.81), while all three Poncirus trifoliata rootstocks showed the lowest numbers. The number of roots and root length per explant were evaluated at the end of the rooting phase. The rootstock 'Swingle' showed a higher number of roots per explant (4.2) followed by 'Flying Dragon' (3.93) and 'Carrizo' (3.23) rootstocks. The rootstocks 'Swingle' (140.8 mm), Volkameriana (148 mm) and 'Flying Dragon' (131.12 mm) had significantly higher root length per explant compared to 'Carrizo' (31 mm) and 'Rubidoux' (34.5 mm). The ISSR molecular marker technique used in the present study grouped successfully the different species, varieties and rootstocks studied, revealing their genetic variability. The genetic variability observed among the rootstocks ranged between 0.29 (Poncirus trifoliata 'Serra' and Citrumelo 'Swingle') and 0.60 (Volkameriana and Citrumelo 'Swingle'). The response of the rootstocks studied in in vitro propagation however is not related to their genetic affinity.

“…More specifically, 'Clementine' mandarin and 'Navelina' orange plants grafted on 'sour orange' rootstock proved to be more sensitive to boron excess than those grafted on 'Swingle citrumelo'. This is mainly due to lower absorption of boron from the roots of 'Swingle citrumelo' and to higher boron retention in the stem of this rootstock, resulting in lesser boron accumulation in leaves of the two aforementioned cultivars when they are grafted on 'Swingle citrumelo' (Papadakis et al, 2004a;2004b).…”

“…each one specific rootstock-scion combination, to adapt to a number of different factors including root-and/or shoot-associated both abiotic [e.g., drought, waterlogging, flooding, salinity, mineral toxicity, mineral deficiency, heavy metal toxicity, heat, cold, low chilling units, low soil temperature, low soil oxygen, wet or poorly drained soils, soils with high calcium carbonate content, high or low soil pH (Papadakis et al, 2004a;2004b;Colla et al, 2010;Hartmann et al, 2013;Savvas et al, 2010;Ghrab et al, 2014;Castle et al, 2016)] and biotic [e.g., fungal and bacterial pathogens, virus and virioid diseases, insect and nematodes (Mudge et al, 2009;Shokrollah et al, 2009;Roistacher et al, 2010;Louws et al, 2010;Castle et al, 2016)]. Furthermore, rootstock can theoretically affect every characteristic of the scion [e.g., overall plant growth, plant shape, fruit shape, fruit weight, fruit color, fruit firmness, content of phytochemicals in fruits and juices and postharvest storability and shelf life of fresh fruits (Ritenour et al, 2004;Rouphael et al, 2010;Orazem et al, 2011;Turhan et al, 2011;Castle et al, 2016).…”
