“…This might be due to better utilization of stored carbohydrates; nitrogen in the semi hardwood with the IBA application enhanced the IBA concentration in the cell and increased the cell division which results on quick callus formation in the cutting as stated by Chauhan and Reddy (1971) [2] in plum. Similar results were reported by Sivaprakash et al, (2018) [15] . Regarding number of leaves per cutting, cutting treated with 3000 ppm of IBA (T6) recorded the highest leaves (5.2) followed by T3 (2000 ppm IBA) whereas the lowest number of leaves (2.80) was observed in T1 (250 ppm).…”

The study on the Influence of IBA on rooting of guava (Psidium guajava L.) through softwood cuttings cv. Lucknow 49 was carried out at College orchard, Department of Horticulture, Agricultural College and Research Institute, Madurai during 2019 -20 with the aim to identify the best IBA concentration suitable for guava softwood cuttings. Nine levels of IBA viz., 250, 500, 1000IBA viz., 250, 500, , 1500IBA viz., 250, 500, , 2000 and 6000 ppm concentrations were prepared and treated with softwood cutting as quick dip method. These cuttings were planted in polybags and kept under mist chamber for sprouting. The study was laid out in a Completely Randomized Block Design (CRD) with nine treatments and three replications. Observations such as sprouting percentage (%), days taken for sprouting (days), number of leaves, shoot length (cm), root length (cm), root weight (g), number of roots per cutting and survival percentage (%) were recorded and analyzed statistically. The results revealed that cuttings treated with IBA solution of 3000 ppm (T6) recorded the highest values of all the traits viz., sprouting percentage (75.50 %), least number of days for sprouting (9.79 days), number of leaves (43.52), shoot length (31.6 cm), root length (3.24 cm), root weight (2.1 g), number of roots (7.2) survival percentage (1.85 g) and root dry weight (110.12 mg) followed by T7 (4000 ppm of IBA) whereas the lowest value was recorded in cuttings treated with 250 ppm of IBA (T1) (54.26 %; 25.90 days; 2.8; 4.50 cm; 18.56; 0.68 g; 3.5; 40.58 %; 99.14 mg). From the conclusion of the present study it was concluded that IBA @ 3000 ppm (T6) treated softwood cuttings recorded the highest values in all the traits and this is one of the alternate method of guava propagation for seedling multiplication.

“…IBA promotes cell division, leading to rapid callus formation in the cutting as observed by Chauhan and Reddy [8] in plum. Similar findings were reported by Sivaprakash et al [9] and in various fruit trees, auxins are essential for the establishment and maintenance of a functional root meristem. Wally et al [10] concluded that guava cuttings treated with IBA exhibited highest success rate.…”

“…Due to its nutritious content, delightful taste, appealing flavor, and year-round availability at a reasonable price, guava has earned a respected place and popularity in the diets of common people in our country. It is highly demanded as a table fruit and as a raw material for processing industries, contributing significantly to earning foreign exchange" [2].…”

Guava can be propagated vegetatively through layering, cutting and grafting, in addition to seeds. Among the propagation techniques, cuttings have gained popularity because they produce results in a shorted span of time. Rooting is an essential step in the propagation of guava through cuttings. Nowadays, the most popular technique for growing cuttings in a misty environment is the use of plant growth regulators, especially auxins such as Indole-3-Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) that promote root growth. The present study was undertaken to assess the influence of plant growth regulators on the rooting of diverse stem cuttings from guava cv. Arka Kiran under mist chamber conditions at the Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu. Two plant growth regulators, IBA and NAA were employed at various concentrations. These regulators were applied to single-node cuttings with one leaf, double node cuttings with two leaves, and herbaceous cuttings. The highest rooting percentage (55.10%), the duration for bud sprouting (21.13 days), and number of leaves (4.83) were observed in single-node cuttings treated with IBA at a concentration of 3000 ppm concentration. Single-node cuttings treated with IBA at 3000 ppm exhibited superior rooting and sprouting performance compared to Naphthalene Acetic Acid (NAA). Among the three stem cuttings, single-node cuttings with one leaf proved to be the most effective for rapid multiplication.

“…It was concluded that the plants produced by this technique will be true-totype and can be used for high density plantation. Prakash et al, (2018) did a study on effect of plant growth regulators on different types of cuttings (softwood, semi hardwood and hardwood cuttings) of guava. Significantly higher sprouting percentage (76.66%) and rooting percentage (74.44%) with early sprouting (19.10 days) was observed IBA treatment @ 4000 ppm on softwood cuttings.…”
