Effect of soaking duration on base stem cuttings in NAA solution (Naphthalene Acetic Acid) on the growth of pepper The need for pepper is increasing along with the development of the food industry with the basic ingredients of pepper. The determining factor of the quality of pepper produced comes from the seeds used. This study aims to determine the effect of soaking DURATION on pepper cuttings (Piper nigrum L.) in the Napthaleneacetic Acid (NAA) solution. The study was conducted in October 2018 until February 2019 in the greenhouse and Plant Science Laboratory of the Faculty of Agriculture, University of Lampung, Bandar Lampung. This study uses a completely randomized group design (RKTS). The treatment of immersion base cuttings in NAA (N) solution concentrates 500 ppm consisting of : without NAA (n0), immersion 0 minutes (n1), soaked 15 minutes (n2), soaked 30 minutes (n3), soaked 60 minutes (n4), and soaked 120 minutes (n5). Homogeneity of variability between treatments was tested by Bartlet Test and data additivity was tested by Tukey test, then continued with Variance Analysis (ANARA). Comparison of the middle value with the orthogonal comparison test at α level of 5%. The results showed that: (1) giving NAA affected the number of roots in the book, the fresh weight of the roots in the book, the dry weight of the roots in the book, the total number of roots, and the total fresh weight of the roots; (2) administration of NAA by immersion is better than dipping in the number of roots in the book, the fresh weight of the roots in the book, the dry weight of the roots in the book, the total number of roots, and the total fresh weight of the roots; and (3) length of soaking cuttings in NAA solution has no effect on the growth of pepper cuttings.

This study investigated growth and ginsenosides content of ginseng sprouts under various light spectra. One-year-old ginseng seedlings were cultivated under various light treatments including: monochromatic (red (R), green (G), and blue (B)), various RB and RGB combinations, white (fluorescent lamps (FL) and natural white (NW)), and supplemental far red (FR). R and high R ratio increased growth characteristics of ginseng sprouts (excepted for root dry weight). The replacement of G for B in RGB group and W group did not increase the growth, and supplemental FR increased shoot and root fresh weights, total fresh weight, and leaf area. R had 1.5 times higher photosynthetic rate compared to B and G, and R8G1B1 and R9G1B0 showed the highest values in RGB group; whereas the RB, W, and FR groups did not enhance photosynthetic rate. B and high B ratio increased shoot saponin and ginsenosides, total saponin and ginsenosides contents. Total saponin content in shoot was 4.4 times higher than that in root. The supplemental FR enhanced both total saponin and ginsenosides contents. In conclusion, NW + FR showed the highest total fresh weight, saponin and ginsenosides contents among all treatments, suggesting that supplementation of FR has a positive effect on ginseng sprouts grown in plant factories.

The present study explores the potential of exogenous auxins in the development of adventitious shoots and roots from shoot cuttings of Couroupita guianensis (Nagalingam), a threatened tree. Experiments were conducted to assess the effect of various concentrations of auxins on shoot and root morphological traits of stem cuttings in the greenhouse. Amongst the auxins tested, significant effects on number of shoot buds’ induction and their growth were observed with α-Naphthalene Acetic Acid (NAA) treated nodal cuttings. Cent percentage of the stem cuttings of C. guianensis were rooted and shoots were induced when pretreated with 400 mg L−1 NAA for 5 min. Maximum 79% of stem cuttings responded to pretreatment of 300 mg L−1 indole-3-butyric acid (IBA) for 5 min, and 75% of stem cuttings induced shoots with 400 mg L−1 indole-3-acetic acid (IAA). Presence of at least 5 nodes on stem cuttings was found to be prerequisite for root and shoot induction. About 92% of plants were survived under natural soil conditions raised from the stem cuttings. This is the first report of vegetative propagation of C. guianensis through stem cuttings which could be used for conservation strategy and sustainable utilization of this threatened medicinal tree.

Research into the symbiotic relationship between plants and arbuscular mycorrhizal fungi (AMF) is key for sustainable agricultural intensification. The objective of the present study is to evaluate native AMF at the monosporic level in greenhouse-grown, economically important crops. Agricultural soil samples from three locations (Saltillo, Zaragoza, and Parras) were obtained by combining portions resulting from a zigzag sampling pattern. From these samples, 15 morphotypes were extracted according to a modified Gerdemann’s technique and monosporically inoculated on melon, cucumber, tomato, and onion, 30 days after their sowing. Under a completely random experimental design, 16 treatments with three repetitions were defined. Plant height, root length, stem diameter, total fresh weight, fresh root weight, dry root weight, bulb weight, fresh leaf weight, total dry weight, flower number, leaf number, fruit number, spore number, and percentage of colonization were all evaluated. The results were subjected to the analysis of variance (ANOVA) and the Tukey comparison test (p ≤ 0.05), which showed that the monosporic inoculation favors significantly the AMF and the host, while the T6 (Saltillo spore + Steiner modified with 20% of the normal phosphorus concentration) showed a greater response uniformity on onion and melon, which indicates its great potential as an inoculum.

Using fruit branch for pepper shrub propagation is one of alternatives for an efficient pepper multiplication which usually uses underlayer cuttings. This research is aimed at finding the growth response of two pepper (Piper nigrum L.) cuttings to the administration of IBA (Indole Butyric Acid) and NAA (Naphthalene Acetic Acid). This research was conducted at the greenhouse of the Faculty of Agriculture, University of Sumatera Utara, Medan (± 32 m above sea level), from April to August 2017 using a factorial randomized block design with 2 factors, pepper branch cuttings (primary branch cuttings and secondary branch cuttings) and the administration of IBA and NAA (0+0 ppm, 2500+0 ppm, 0+2500 ppm, 1500+1000 ppm, and 1000+1500 ppm). The results show that the emerging shoot rate in the secondary branch cuttings was significantly faster than in the primary branch cuttings, but the volume of root in the primary branch cuttings is significantly larger than in the secondary branch cuttings. There was no significant difference in the administration of IBA and NAA on all observed variables. The highest interaction of shoot length was found in the  primary branch cuttings with the administration of  IBA 1500 ppm + NAA 1000 ppm and the highest percentage of root and root volume was found in the primary branch cuttings with the administration of IBA 2500 ppm + NAA 0 ppm.

ABSTRACT The objective of this work was to evaluate the effect of six indole-3-acetic acid (IAA) concentrations and three immersion times in IAA solutions on the vegetative propagation of Spondias dulcis and Spondias tuberosa by stem cuttings. The experiment was conducted in a greenhouse, using a completely randomized design, with a 6×3 factorial arrangement consisting of six indole-3-acetic acid concentrations (0, 2, 4, 6, 8, and 10 g L-1) and three immersion times (8, 16, and 24 seconds), with ten cuttings of S. dulcis and S. tuberosa per plot, and three replications. Percentage of surviving cuttings, and percentage of rooted cuttings, number of leaf buds, number of roots per cutting, root length, and total fresh weight were evaluated at 180 days after planting. Data were subjected to analysis of variance by the F test and to regression analysis. Vegetative propagation from woody cuttings of S. dulcis is not viable to produce seedlings, thus, new studies on this technique for this species are needed. Vegetative propagation from woody cuttings of S. tuberosa is satisfactory, but with low efficiency for improvement and emergence of new shoots and roots; it is more effective when using a concentration of 10 g L-1 of indole-3-acetic acid and immersion time in the solution of 16 seconds.

Experiments to determine the effect of seed size, watering interval and defoliation on growth and dry matter attributes of seedlings of shea butter tree were conducted at Makurdi, Nigeria, from July 2010 to April, 2012. In the first experiment, treatments were made up of three seed size categories described as small (5-10g), medium (11-15g) and large (16-20g) and three watering intervals of 3, 6 and 9 days. In the second experiment, treatments comprised three watering intervals of 3, 6 and 9 days and three levels of defoliation – 0, 50 and 100%. In both experiments, factorial combinations of the treatments were laid out in completely randomized design (CRD) and replicated three times. Results of analysis of variance showed that in the first experiment seed size significantly influenced root length with the medium and large seeds producing seedlings with comparatively longer roots than the small seeds. The most frequently watered seedlings (3 and 6 days) produced more leaves than those watered less frequently (9 days). Seed size influenced dry weight of root and total (whole plant) dry weight with the medium and large seeds recording significantly higher values than the small seeds. Watering interval however did not significantly influence any of the other traits. Seed weight exerted significant influence on amount of dry matter partitioned to the stem and the root. More dry matter was partitioned to the stem by the small seeds. Conversely, medium and large seeds allocated more dry matter to the root than to the stem. In the second experiment, defoliation level only influenced total fresh weight, dry weight of root and total dry weight in favour of plants with half their leaves removed. None of the traits examined were significantly influenced by watering regime. Interaction between defoliation level and watering regime significantly influenced total fresh weight, dry weight of root and total dry weight. Generally seed size had more influence on seedling characters than watering interval. Seedlings also demonstrated remarkable ability to overcome effects of defoliation.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from December 2009 to March 2011 to determine the effect of date of planting on growth and leaf yield of Stevia. The experiment comprised 24 dates of planting in the year of 2010 viz. 1 January (T1), 15 January (T2), 1 February (T3), 15 February (T4), 1 March (T5), 15 March (T6), 1 April (T7), 15 April (T8), 1 May (T9), 15 May (T10), 1 June (T11), 15 June (T12), 1 July (T13), 15 July (T14), 1 August (T15), 15 August (T16), 1 September (T17), 15 September (T18), 1 October (T19), 15 October (T20), 1 November (T21), 15 November (T22), 1 December (T23) and 15 December (T24). The experiment was laid out in a Complete Randomized Design with three replications. Twenty four dates of planting were included in the experiment in 72 earthen pots (24 X 3) of 30 cm diameter X 30 cm height. Stem cuttings were placed in shaded seed bed for root initiation. Twenty one - day old stem cuttings were used as planting material. Stem cuttings were transplanted in the pots on the specific dates. Different dates of planting had significant effect on the growth and yield parameters. 1 April 2010 (T7) planting proved to be the superior to the other treatments i.e. plant height (68.50cm), number of leaves plant-1 (142.33), number of primary branches plant-1 (37.33), fresh weight of leaves plant-1 (14.11g), fresh weight of primary and secondary branches plant-1 (11.06g and 20.91g), dry weight of leaves plant-1 (3.38g) which might be due to warm environmental conditions like clear sunshine and high temperature. The overall results suggested that stevia seedlings may be planted from 15 February to 30 April for better yield of leaves. DOI: http://dx.doi.org/10.3329/jbau.v10i2.14684 J. Bangladesh Agril.
