“…In a study of 21 Populus clones from different genomic groups, it was observed that cuttings originating from the basal third of the shoot system of the stool plant exhibited greater rooting-related traits, such as root dry mass, number of roots and total root length, than those from the apical and middle positions ( Zalesny et al, 2003 ), and the differences observed were genotype-dependent ( Zalesny and Wiese, 2006 ). Similar results were obtained in four different stone fruits and the difficult to root Lobostemon fruticosus where cuttings collected from the basal part presented better rooting performance than those collected from the apical part of the plant ( Swarts et al, 2018 ; Tsafouros et al, 2019 ).…”

Populus spp. are among the most economically important species worldwide. These trees are used not only for wood and fiber production, but also in the rehabilitation of degraded lands. Since they are clonally propagated, the ability of stem cuttings to form adventitious roots is a critical point for plant establishment and survival in the field, and consequently for the forest industry. Adventitious rooting in different Populus clones has been an agronomic trait targeted in breeding programs for many years, and many factors have been identified that affect this quantitative trait. A huge variation in the rooting capacity has been observed among the species in the Populus genus, and the responses to some of the factors affecting this trait have been shown to be genotype-dependent. This review analyses similarities and differences between results obtained from studies examining the role of internal and external factors affecting rooting of Populus species cuttings. Since rooting is the most important requirement for stand establishment in clonally propagated species, understanding the physiological and genetic mechanisms that promote this trait is essential for successful commercial deployment.

“…As far as the part of the mother shoot used as the cutting source is concerned, the present results indicated that the middle part of girdled cuttings exhibited the highest rooting percentage (Tables 1 and 2). Similar results have been reported for a variety of plants, i.e., Lobostemon fruticosus [47], Santalum austrocaledonicum [49], and the rootstocks GF 677, Rootpac-R and Cadaman [45]. The concentration of the endogenous co-factors found in the present study may explain the different response of the two types of cuttings; the middle part was characterized by higher concentrations of sucrose, glucose, mannitol, free PAs, total phenolic compounds, luteolin-7-glucoside, and rutin (Figures 3-7).…”

“…The type of the cutting (basal or middle part), as well as the time of cutting collection, may also influence the rooting potential of Kalamata cuttings (Tables 1 and 2). Seasonal and even monthly or weekly changes in rooting performance have been reported in stone fruit rootstock cuttings [45], in Prunus cuttings [18,46], in Lobostemon fruticosus [47], and in many other species as well. These reports indicate that the rooting potential of the cuttings is significantly affected by the physiological state of the plant.…”

“…These reports indicate that the rooting potential of the cuttings is significantly affected by the physiological state of the plant. According to Hartmann et al [4] and Tsafouros et al [45], the different ratio of endogenous root-promoting versus -inhibiting factors and/or the level of reserves changes with time, and therefore influences rooting performance.…”

Girdling (a ring of bark approximately 5 mm wide) was applied on olive mother plants to investigate its effect on the rooting ability of cuttings. Treatment was applied in autumn and in spring. The cuttings were then immersed for 5 s into 2000 mg L−1 indole-3-butyric acid (IBA) in a 45% v/v ethanolic solution. Thirty days after girdling, cuttings were taken from girdled and control shoots from the part just above the girdle zone (basal), as well as from the part right above (middle). The base of the cuttings was collected, and the concentration of polyamines, phenolic compounds and soluble carbohydrates was determined. Girdling enhanced the rooting performance of the cuttings, while autumn proved to be a better season for rooting compared to spring. Girdling positively affected the concentration of all the measured parameters. The main characteristics of autumn cuttings were the high levels of glucose, mannitol, free and total polyamines, hydroxytyrosol, tyrosol, verbascoside, oleuropein, quercetin and luteolin. The cuttings taken from the middle part of the girdled shoot exhibited high sucrose, glucose, mannitol, free polyamines, hydroxytyrosol, luteolin-7-glucoside, total phenols and flavanol concentrations. Nonetheless, further research is needed in order to draw conclusions on the overall efficiency of girdling on inducing rooting of olive cuttings.

“…Work is underway to study the dynamics of the growth of thin roots in grapes [8]. The influence of mineral nutrients, carbohydrates, trace elements, strigolactones and brassinosteroids on the development of vines and fruit crops is studied [9][10][11][12][13][14]. However, there is practically no data in scientific literature on the effectiveness of natural growth regulators use and there is only general information about technological parameters of their application, including yeast.…”

Regenerative ability of grape cuttings under the influence of yeast suspension treatment

et al. 2021

The paper presents the growing experiment results on activating the regenerative ability of Moldova table variety grape cuttings by processing pressed baking yeast suspension. The present circumstance became the basis for conducting special studies to check cutting response to the treatment with baking yeast suspension, with the identification of drug optimal concentration. In spring, the two-eyed cuttings were completely soaked for 24 hours in water, and then they were placed with the basal ends in yeast suspension at various concentrations for the same time. Moreover, these yeast suspension concentrations were tested both in pure form and in combination with 3% sucrose. As a result of the conducted studies, it was revealed that pressed baking yeast suspension at certain concentration can have an activating effect on regenerative ability of grape cuttings. The use of yeast suspension together with sucrose solution increases their physiological activity. It was found that cuttings basal end soaking in yeast suspension at concentrations of 10-20 g/l, together with sucrose, contributed to rooting increased by 20-30%, the proportion of cuttings with three roots or more – by 22.5-30.0%, the number of roots by 13.5–16.2%. The best option was with a yeast suspension concentration of 20 g/l.
