Rooting Response of Five Pomegranate Varieties to Indole Butyric Acid Concentration and Cuttings Age

Abstract

The purpose of this study was to evaluate the effect of cutting age and Indole Butyric Acid (IBA) treatments on five pomegranate varieties propagation by stem cuttings. The experiment was carried out in a partially controlled glasshouse conditions at Mutah University, Jordan. The treatments comprised of two types of cuttings, i.e., hardwood and semi-hardwood; five concentrations of IBA, i.e., 3,000, 6,000, 9,000 and 12,000 ppm as quick dip (10 sec) as well as five Jordanian pomegranate varieties (Kdaree Hello, Hmadee Hmaree, Kdaree Sfaree, Zeklabi, Maleese). In this study, the percentage of cuttings that rooted, the number of roots produced per cutting, root length and diameter and root weight per cutting were recorded. It was obvious that the rootability of pomegranate is influenced by the interactive effect of cuttings age, IBA concentration and variety as well as by the single effect of either. The cuttings taken from hardwood stems had higher rooting percentage than those taken from semi-hardwood stems with a considerable differences in rootability between varieties under this study. The highest percentage of cuttings that rooted was observed in Hmadee Hmaree (70%), Zeklabee (69%) and Malesse (73%), while the lowest rooting percentage in Khdaree Hello (58%) and Kdaree Sfaree (49%) varieties. Zeklabee and Hmadee Hmaree varieties when compared with other varieties gave more favorable results at 6000 to 9000 ppm IBA in terms of the percentage of cuttings that rooted, the number of roots produced per cutting and root weight per cutting using both semi- and hard-wood cuttings. It was concluded that the increasing dose of IBA could be useful in increasing rooting potential and other root characteristics in pomegranate.

Effects of cutting length, time and growing media on the sprouting of dormant semi-hardwood cuttings of pomegranate cv. Wonderful

“…DBS: days before sprouting. Owais (2010) who recommended 20 cm cutting length for optimum propagation of pomegranate. Significantly, similar performance of 10 cm length cuttings with the cuttings of 20 cm length is a valuable result in which number of plants might be doubled by dividing the 20 cm cuttings into two; while at the same time the sprouting percentage of the cuttings would be better.…”

“…The most important problem for cuttings method is the high mortality rate (Sharma et al, 2009) which strongly varies among varieties (Owais, 2010), cutting length, time of the year (Sebastiania and Tognettib, 2004) and cultivation practices applied. It was previously reported that indole-3-butyric acid (IBA) (Sharma et al, 2009;Sarrou et al, 2014), ascorbic acid, gibberellic acid (GA3), hydrogen peroxide (H 2 O 2 ) and melatonin (MEL) (Sarrou et al, 2014) have positive effects on the rooting, root number, root length and shoot length of pomegranate cuttings.…”

“…The carbohydrate sink of the cuttings is important for sprouting, as it is required for the cuttings until it rooted (Chadha, 2001). Many studies have been conducted on the propagation of pomegranate (Polat and Caliskan, 2006;Sharma et al, 2009;Owais, 2010;Karimi et al, 2012;Sarrou et al, 2014;Chater et al, 2017), however no experiments are known to study the effects of cutting length, time and rooting media on the rooting of pomegranate cuttings. Thus, this present study aimed to determine the effects of cutting length, cuttings' collection time of the year and rooting media on the sprouting of dormant semi-hardwood cuttings collected from pomegranate (cv.…”

Roots of Mini-Cutting of Clones of Sequoia Sempervirens in Different Seasons of the Year

“…The variation in rooting capacity is similar to that found by Pereira et al (2017) in Sequoia sempervirens and other woody species such as Chamaecyparis nootkatensis (Krakowski et al, 2005), Taxus globosa (Muñoz-Gutiérrez et al, 2009) and many others. The clonal variation in rooting capacity is an attribute in many studies on genetic effects (Owais, 2010) and "C" clonal effect; the latter defined as unique physiological or morphological characteristics for the branch (stake) reflecting in its growth environment.…”

Evaluation of Genetic Diversity among Jordanian Pomegranate Landraces by Fruit Characteristics and Molecular Markers

“…In total, 14 pomegranate landraces were localized in farmers' field, namely; 'Khashaby', 'Khdaree Hello', 'Malesse', 'Bradee Sharabee Asfar', 'Hasmasi', 'Hmaree Hmadee', 'Bradee Sharabee Ahmar', 'Zeklabee', 'Zokom Albagel', 'Khratee', 'Ahmar Hello', 'Khdaree Hmadee', 'Lfani Sharabi', 'Zarori and Esari'. The fourteen Jordanian pomegranate landraces were propagated by stem cuttings according to the conditions proposed by Owais (2010). Thereafter, rooted cuttings were planted in plastic bags to be conserved at Mu'tah University Agricultural Station ex situ.…”
