“…It is suggested that the level of carbohydrate and other root-inducing factors might be lower for rooting. Palanisamy and Kumar (1997) stated that in neem the cuttings from distal end gave better rooting than proximal end and their finding were in accordance of our results. Among different environmental factors, temperature, light intensity and relative humidity are the main factors which influence the growth and development of plants considerably.…”

“…Effect of different concentration of indole-3-butyric acid on the dry matter accumulation of leaves, twigs and thickness of stem cuttings and roots of C. Wightii were recorded earlier (Kumar et al 2006). It has been established in the literature that environmental factors, seasons, age and size of cuttings influence rooting in the tree species (Soundy et al 2008;Palanisamy and Kumar 1997).…”

Studies were carried out to standardize and develop a suitable macro-propagation technology for large scale production of superior clonal stock through stem cuttings in Commiphora wightii Arnott (Bhandari), a data deficient medicinal plant of arid region. For the purpose, three experiments were conducted. The first experiment was tried to elucidate the impact of various cutting diameters (0.50-0.75 cm, 0.75-1.00 cm, 1.00-1.50 cm, and ＞1.50 cm) in combination with varying growing conditions (sunlight, shade house and mist chamber) on shoot sprouting and rooting without using exogenous plant growth regulators. Cutting diameter (size 0.75-1.00 cm) in mist chamber has shown maximum sprouting (90.00%) and rooting (73.33%), primary root (6.67) and secondary root (16.67) followed by 1.00-1.51 cm in mist chamber. Minimum sprouting (40.00%), rooting (33.33%), number of shoot (1.33), primary root (1.00) and number of secondary root (1.00) was recorded in cutting diameter (size ＞1.50 cm) in sunlight. Second experiment was performed to find out optimum growth regulator concentration of rooting hormone (100, 200, 500 and 1000 ppm) of Indole-3-acetic acid (IAA) and Indole-3-butyric Acid (IBA) on adventitious root formation on cuttings diameter (size 0.25-0.50 cm) in comparison to control. Maximum rooting percentage (93.33%) was recorded in 200 ppm followed by 500 ppm (86.66%) of IBA as compared to control, which showed only 60 per cent sprouting. Third experiment was performed with newly formed juvenile micro-cuttings treated with varying concentrations of IAA and IBA. The juvenile cuttings (size 6-10 cm, basal dia ＜0.25 cm) were selected as micro-cuttings. The cuttings treated with IBA (500 ppm) showed 64.30% rooting as compared to other treatments. Results of above experiments indicate that cuttings (size 0.75-1.00 cm dia) may be developed in mist chamber for better performance. While using heavier cuttings, no growth promoting hormones is required however; growth regulator 200 ppm concentration of IBA rooting hormone was observed optimum for promoting macro-propagation in stem cuttings of lower diameter class (0.25-0.50 cm).

“…More number of rooting using apical cuttings was also reported by Deen and Mohamoud, (1996) for rosemary (RosemarinusofficinalisL.) and by Palanisamy and Kumar, (1997) for neem (Azadirachtaindica A. Juss). Wassner and Ravetta, (2000) also reported good propagation ability for top cuttings than none of the basal cuttings in Grindelia chiloensis.…”

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/seedling and survival count were collected and analyzed except for root length/seedling in dry season. Cutting size exerted a significant influence (P<0.05) on all of the parameters considered in this study except on root length/seedling in dry season experiment. Cutting position also exerted a significant influence (P<0.05) on all of the parameters except on branch number/seedling, root length/seedling and root weight/seedling during dry season experiment. Interaction effect of cutting size and cutting positions didn't excreted a significant influence (P>0.05) on majority of the agronomic characters. But its effect was significant (P<0.05) on seedling height and root length/seedling during wet season experiment and on seedling height and branch number/seedling during dry season experimentation. Different perpetuation abilities of sage were observed in dry and wet season experiment. Top cuttings having a cutting length starting from 9 cm to 12cm can be recommended for sage propagation in wet season. However, bottom cutting position from 12cm to 15cm cutting size can be recommended for propagating sage in dry season using stem cuttings.

“…The first factor is that the level of endogenous auxins and other rooting-inducing factors may be lower in smaller cuttings, which leads to reduced rooting percentage (Fig. 4) or the absence of rooting in short cuttings (Palanisamy and Kumar 1997). The second factor is that larger cuttings store more carbohydrates (Tchoundjeu and Leakey 1996).…”

The effects of cutting length, cutting diameter, and exogenous hormone pretreatment on rooting were studied in comparative experiments to improve the efficiency of cutting propagation in Norway spruce. The results showed that cutting length, diameter, and the interaction between cutting length and diameter significantly affected rooting efficiency. Higher rooting efficiency was obtained by cuttings of 0.3-0.4 cm diameter and 9-12 cm length. Hormone type significantly affected all measured rooting traits, and moderately higher measurements were observed in the indole butyric acid treatment than those of the control, whereas all measurements in the a-naphthalene acetic acid treatment were significantly lower than those of the control, which may have been an inhibitor of Picea abies in stem cuttings. The cutting size effect on rooting efficiency is discussed and an optimal cutting size is suggested, which provide valuable information for propagating Norway spruce.
