International Journal of Chemical Studies, 2021
The study was conducted to find out "Effect of Indole butyric acid (IBA) on cutting on rooting of Ixora" at farm of Horticulture Section, College of Agriculture, Nagpur in 2019-2020. The experiment was laid out in Factorial Completely Randomized Design with fifteen treatments and three replications. The treatments comprised three types of cuttings i.e. Softwood cuttings, Semi hardwood cuttings and Hardwood cuttings and five concentrations of IBA, 0 ppm, 1000 ppm, 2000 ppm, 3000 ppm, 4000 ppm. The result obtained from the present investigation in respect of root parameters, it was observed that, minimum days to rooting was observed in treatment T13 (hardwood cuttings treated with IBA 2000 ppm). However, maximum number of roots cutting-1 , length of main root, survival percentage of rooted cuttings, root volume, fresh weight of roots cutting-1 and dry weight of roots cutting-1 was noticed in hardwood cuttings with 2000 ppm IBA.
This study was carried out in the Agricultural College/ Salahalden University during the period between to investigate the effect of planting media (sand, sand: loamy soil, and mixture of sand: loamy soil: peat moss) 1:1:1 by volume, and IBA concentrations (0, 1000, 2000, 3000) mg.l-1 on rooting ability of stem cuttings of Ligustrum ovalifolium. The results show that the mixture of sand, loamy soil, peat moss is significantly superior than other media and give the highest values of roots number 7.45 root/plant, roots dry weight 0.33 gm/plant, shoot number 3.92 shoot/plant, leaf number 11.00 leaf/plant, and vegetative dry weight 3.76 gm/plant while the best rooting percentage 64.63% is obtained in cutting which are planted in peat moss and the longest root is for cutting which are planted in sand media. The 2000 and 3000 mg.l-1 IBA causes significantly increase in rooting percentage 68.92, 68.42%, longest root 3.41, 3.36 cm, roots dry weight 0.31, 0.31 gm, leaf number 9.67, 9.56 leaf/plant when comported with the other concentration. In the other hand the 3000 mg.l-1 is significantly superior in roots number 5.91 root/plant, shoots number 3.92 shoot/plant, and vegetative dry weight 2.82 gm/plant. The interaction between planting media and IBA concentrations case significantly variance in all rooting and shooting parameters and the highest values are for cutting treated with 2000, 3000 mg.l-1 and planted in deferent media.

The objective of the current review is to review and identify the research on the effect of IBA, NAA and their combination effect on shooting and root growth of ornamental crops specially African marigold (Tagetes erecta L.) cuttings. Factors affecting rooting of ornamental crops cuttings can be internal or external factors. Internal factors affecting rooting of cuttings include the amount of stored food in cuttings, the age and maturity of tissue, the formation of callus and adventitious roots and the presence of leaves and buds on cuttings. The external factors include rooting media, chemical and hormone treatments, light, temperature, mechanical treatment and mist spray. IBA, NAA is one of the most important factors for cutting production. Types of rooting hormone have significantly influenced the rooting and vegetative growth of cuttings. The concentration of rooting hormone depends on the species, type of cuttings, growing conditions, season of the year and the cost effectivene...

Background: Queen's flower (Lagerstroemia speciosa) is an important ornamental plant that is utilised in residential landscape and avenue plantation for both public and private purposes around the world. Seed dormancy problem in Lagerstroemia which negatively affects germination. To overcome the challenges associated with seed propagation, researchers have explored rooted Lagerstroemia speciosa cuttings as an alternative method. Methods: Three concentrations of IBA (Indole-3-butyric acid) @ 1000 ppm, 2000 ppm and 3000 ppm were used to root initiation of Lagerstroemia speciosa stem cuttings. There were four treatments: 1000 ppm, 2000 ppm, 3000 ppm and control. Result: The 2000 ppm IBA treatment performed the better response in comparision to other treatments and recorded, 79 per cent rooting, followed by the treatment 3000 ppm IBA, (76 per cent rooting) and in the control, (68 per cent). In 2000 ppm IBA, the percentage of rooting, the number of roots per cutting and the length of the longest roots all are at their peak as well as showed the superior growth performance. The growth parameters of IBA-@ 2000 ppm treated cuttings revealed that this is the optimum IBA concentration for Lagerstroemia speciosa propagation trough cuttings in a semi-arid climate.
One of the problems with commercial cultivation of poinsettia is damage to the plant during propagation. In this research the propagation process has been examined to help to facilitate better rooting. This project was conducted in the form of factorial test in a randomized complete block design with 12 different treatments and 3 replications. In this experiment 3 forms of cutting were applied; top cutting, middle cutting, lower cutting. After the insertion of IBA (Indole 3-Butyric acid) at four different densities; 0, 1000, 2000, 4000 mg/L in 2.5 centimeters of the lower part of the cuttings for 5 seconds, they were planted in washed sand then the planted cuttings were put under a mist system, so that after 5 weeks they were rooting. The results showed that the plants produced from lower cutting had the maximum level of rooting, evident from the data for; number of bracts, number of leaves, number of buds and size of bract. The highest increases in length of root, number of bracts, number of cyathium, number of leaves and size of bract were recorded with applications of an IBA density of 1000 mg/L. The tests showed that the most rooting was from top cutting and IBA for rooting was not necessary, and that the IBA density of 2500 mg/L was suitable for increasing the speed of rooting and uniformity of root growth, but according to the results of this research, IBA with density of 1000 mg/L caused longer roots and the most rooting was from the lower cutting.
IBA Induced Rooting Characteristics in Marathi Moggu Stem Cuttings: Evaluation Using SVI Concept
International Journal of Current Microbiology and Applied Sciences
Rooting ability in IBA induced stem cuttings in vegetative regeneration experiments largely depends on various parameters, which has been established using SVI (sprouting value index), a mathematical approach. Marathi-moggu the Bombax ceiba tree is a medicinal and avenue tree species of tropical India that has known to have poor regeneration through seeds and hence in the present study stem cuttings of saplings were used to generate clonal plant propagules. Field studies were carried out using three rooting medium at a location in Central Kerala, Peninsular India, for one year at four months regular interval. Three IBA (Indole 3butyric acid) concentrations 300 ppm, 500 ppm and 1000 ppm IBA, have been used and the data obtained was evaluated with SVI (sprouting value index) method in order to evaluate the suitable medium, which gives maximum results. The control cuttings do not recorded rooting. The results obtained indicate high SVI (sprouting value index), when stem root cuttings planted in root trainers with coir pith compost (RTCP) for all the three concentration of IBA applied. Sprouting percentage was increased and the delay in completion of sprouting/rooting initiation decreased by the use of IBA treatment.

An experiment was carried out at the Department of Horticulture at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh for the investigation of the performance of different concentration of Indole-3-Butyric Acid (IBA) for sprouting and rooting potential of Bougainvillea spectabilis stem cutting during the period from May 2013 to August 2013. Five treatments viz. T0: Control; T1: IBA in dust form; T2: IBA 500-ppm; T3: IBA 1000-ppm and T4: IBA 2000-ppm were exploited on the experiment with five replication. In case of T2, T3 and T4 cuttings were soaked for 24 hours on the respective solutions. From the experiment it was found that IBA play an important role for successful asexual propagation of bougainvillea through cutting. Better performance was found when cut stems were soaked for 24 hours before the establishment of stem cutting. But performance was inhibited by increasing concentrations of IBA in terms of all of the features on which data had taken. During the experimental period, data was taken on different attributes and T3 (1000-ppm) was performed as the best among the treatments which as followings: days to first rooting (4.0), days to first sprout bud initiation (5.3), number of sprout bud/cutting (3.6), number of leaves/cutting (35.2), length of sprout (15.0 cm), number of branches/cutting (4.7), number of root/cutting (64.2), number of sub root/cutting (25.8), longest root length (33.2 cm), longest root diameter (0.51 mm), rooting % (100%), survival % of rooted cuttings (100%). Though 100% rooting was also found in 500-ppm and 2000-pmm but only 1000-ppm was resulted 100% survival of rooted cuttings.

Autumn olive berry is used as functional food due to the very high content of lycopene. It is a deciduous, perennial, temperate and/or subtropical berry fruits and has a woody bush. Autumn olive leaves, flowers, berries and bushes can be used for many purposes. It grows well at sunny areas and tolerates dry conditions with salty, clay, sandy and different pH soils. Autumn olive berry can be diverse with its seed eaten by birds. Cultivated autumn olive berry types generally propagate by cuttings. In the present study, hardwood, leafy green wood and semi hardwood cuttings taken from mother plants of autumn olive berry at March 15, May 15 and July 15. All type of cuttings applied with 0 ppm (control), 500 ppm, 1,000 ppm and 2,000 ppm Indole-3-butryic acid (IBA) doses. Cuttings were planted in benches with perlite under misting at greenhouse conditions for rooting. The effect of cutting time and IBA application on the rooting rate (%), root number, rooting degree (1-9), diameter and length of the saplings (cm) and salable sapling rate (%) were determined. Pearson correlation among the features studied was also calculated. Cuttings taken at May with 1,000 or 2,000 ppm IBA and June with 500 ppm gave the highest rooting rate (97.33%). Root length is the best (11.90 cm) at May cuttings with 500 ppm IBA. May cuttings with 1,000 ppm IBA gave the best salable sapling rate (89.33%). The best cutting time was 15 May and the best IBA dose is the 1,000 ppm for most characteristics, investigated.

In this research, in order to study the effect of different concentrations of IBA and time of taking cutting on rooting, growth and survival of F. binnendijkii 'Amstel Queen' cuttings, a test was conducted in a randomized complete block design with four replications. Treatments were consisted of four levels of hormones: 0 (control), 2000, 4000 and 6000 mg/l, with two intervals of time for taking cuttings (late June and early September). Results showed that highest root percentage, root number and fresh weight of root were for IBA concentrations of 4000 and 6000 mg/l and cuttings taken early in September. The maximum of mean length of root and longest root were achieved in concentration of 6000 mg/l IBA, taking cutting in early September. The highest survival percentage of plants was recorded in concentrations of 4000 and 6000 mg/l IBA, early September being the appropriate time of taking the cutting. The greatest length of new shoots was obtained in concentration of 4000 mg/l IBA, cutting in late June, while the maximum number of new leaf was in IBA concentration of 2000 and 4000 mg/l, with cuttings taken also in late June.
