Influence of IAA and IBA on root development and quality of Prunus 'GiSelA 5' leafy cuttings

The influence of two exogenously applied auxins (IAA and IBA) on the root and shoot development of leafy cuttings was analyzed at 'GiSelA 5', the dwarfing cherry rootstock. IBA (indole-3-butyric acid) hindered the callus formation in the early period of root development and it was more successful than IAA (indole-3-acetic acid) in promoting earlier root development. IBA also influenced the stronger shoot growth and the development of acrobasal type of the rooting system, and induced higher number of roots. Those parameters are very important for the quality and survival of the new plants and they are not the consequence of the higher IAA content in the rooting zones of cuttings in the first days of root development. Both auxin treatments had no effect on the final percent of the rooted cuttings neither on the survival of cuttings, but they increased the percent of rooted cuttings without callus. The root system with callus proved less qualitative, because the cuttings with such root system developed significantly less roots per rooted cutting and their shoot length was shorter than those of the cuttings without callus at both auxin treatments. Exogenously applied auxins were not crucial for root formation, however their application resulted in higher percent of more qualitative 'GiSelA 5' leafy cuttings. IBA proved as the most efficient treatment and it additionally induced earlier root formation.

  A study was made of the stimulating effect of benzolinone (3-benzyloxycarbonyl-methyl)-2-benzothiazolinone in powder form (P) and its mixture with indole butyric acid (IBA), the biofungicide Supresivit and fungicide Captan 50 WP on the root formation of 17 species of ornamental plants, park and fruit woody species. Under the action of benzolinone, the yield of rooted cuttings in the category of ornamental plants amounted to 44.5% (in the Dianthus sp.) up to 83.7% (in Rosa canina), in the category of park woody species it was from l6.7 (in Magnolia stellata) to 100% (in Forsythia intermedia). In fruit trees represented by two species, viz. Actinidia arguta and cherry rootstocks, the yield was between 20 and 86.7%, and in two allochthonous species Cotoneaster horizontalis and Philadelphus coronarius it was from 96.7 to 100% in rooted cuttings. In the case of herbaceous and semi-lignified cuttings, lower concentrations of benzolinone below 0.1% were more effective, while on the contrary, higher concentrations of 0.1–0.2% proved more effective with lignified cuttings. In the species with difficult root formation, such as Magnolia stellata, Viburnum farreri and Actinidia arguta, benzolinone demonstrably stimulated both the rhizogenesis, and thereby the overall yield of rooted cuttings, and the quality of the root system. In the case of the species with naturally high rooting ability, the positive effect of benzolinone was manifest mainly in the quality of the root system. The synergistic action of the above stimulants on root formation was achieved in two and three-component benzolinone mixtures with IBA and fungicides on the basis of the active ingredients captan and Trichoderma harzianum. The most evident stimulating effects on the rooting of cuttings in Dianthus sp., Ficus schlechteri and the deciduous species Acer saccharinum Pyramidale, Prunus padus Colorata and Prunus kurilensis Brilliant was obtained in three-component mixtures.

Bedding Plant

Cuttings of herbaceous annual bedding plants must be rooted in late winter and early spring when ambient outdoor photosynthetic daily light integrals (DLIs) are at seasonally low levels. We evaluated the effect of DLI during root development on growth, morphology, and quality of nine popular vegetatively propagated annual bedding plant species. Cuttings of Angelonia angustifolia Benth. ‘AngelMist White Cloud’, Argyranthemum frutescens (L.) Sch. Bip. ‘Madeira Cherry Red’, Diascia barberae Hook. f. ‘Wink Coral’, Lantana camara L. ‘Lucky Gold’, Nemesia fruticans (Thunb.) Benth. ‘Aromatica Royal’, Osteospermum ecklonis (DC.) Norl. ‘Voltage Yellow’, Scaevola L. hybrid ‘Blue Print’, Sutera cordata Roth. ‘Abunda Giant White’, and Verbena Ruiz ×hybrida ‘Aztec Violet’ were harvested and propagated in a glass-glazed greenhouse with 23 °C air and substrate temperature set points. After callusing (≈5 mol·m−2·d−1 for 7 days), cuttings of each species were placed under one of three different fixed-woven shade cloths providing ≈38%, 61%, or 86% shade or no shade with 16 h of supplemental light for 14 days. There were no clear trends across species for stem length in response to DLI. Stem caliper of Argyranthemum, Diascia, and Nemesia increased by 35%, 119%, and 89%, respectively, as DLI increased from 1.2 to 12.3 mol·m−2·d−1. Depending on species, total, shoot, and root dry mass increased by 64% to 465%, 50% to 384%, and 156% to 1137%, respectively, as DLI increased from 1.2 to 12.3 mol·m−2·d−1. The quality index, an objective, integrated, and quantitative measurement of rooted cutting quality, increased for all species by 176% to 858% as DLI increased from 1.2 to 12.3 mol·m−2·d−1. Our results indicate that providing a DLI of ≈8 to 12 mol·m−2·d−1 after callusing increases both growth and quality of rooted cuttings.

Lateral Root Development

Abstract Lateral roots are important to forage for nutrients due to their ability to increase the uptake area of a root system. Hence, it comes as no surprise that lateral root formation is affected by nutrients or nutrient starvation, and as such contributes to the root system plasticity. Understanding the molecular mechanisms regulating root adaptation dynamics towards nutrient availability is useful to optimize plant nutrient use efficiency. There is at present a profound, though still evolving, knowledge on lateral root pathways. Here, we aimed to review the intersection with nutrient signaling pathways to give an update on the regulation of lateral root development by nutrients, with a particular focus on nitrogen. Remarkably, it is for most nutrients not clear how lateral root formation is controlled. Only for nitrogen, one of the most dominant nutrients in the control of lateral root formation, the crosstalk with multiple key signals determining lateral root development is clearly shown. In this update, we first present a general overview of the current knowledge of how nutrients affect lateral root formation, followed by a deeper discussion on how nitrogen signaling pathways act on different lateral root-mediating mechanisms for which multiple recent studies yield insights.

This article presents data on the rooting of green cuttings of the studied species of ornamental trees and shrubs in a greenhouse with a misting system. We accounted the number of days from planting to the root formation and the number of rooted cuttings for each replication during our performance. We studied the influence of root formation stimulants on the rooting rate of various types of ornamental deciduous, flowering and coniferous plants. The effect of application of root formation stimulants is confirmed by the formation of a high-quality root system that is superior in length to those that were vegetated without “Kornevin”. However, the use of root formation stimulants is not advisable on shrubby cinquefoil, common privet and common lilac “Mademoiselle Casimir Perier”, because there is practically no increase in the rooting rate of cuttings in these plant species, compared to the control plants.

Abstract Lavender cotton (Santolina chamaecyparissus L.) shoot cuttings, obtained from two-year-old mother plants, were rooted in five different media under an unheated foil tunnel. Two ready-made and widely recommended media were used: Hartmann peat substrate and Ceres peat-coconut substrate, as well as three prepared mixtures: high peat + mineral soil, high peat + perlite and high peat + sand. The influence of medium type on the number of rooted cuttings and the quality of the root system was assessed for two cultivation times during a three-year study after eight weeks from the date of cutting. As far as the ready-made rooting substrates are concerned, Ceres peat-coconut substrate turned out to be better when compared with the Hartmann substrate. The number of high quality rooted cuttings was larger when media containing high peat mixed with either mineral soil or sand were used in comparison with the mixture of high peat and perlite.

Methods Of Application

`Arp' rosemary cuttings were treated with indole butyric acid (IBA) using three different application procedures to determine speed and quality of rooted cuttings produced at three weeks under mist. Five concentrations of IBA, 0%, 0.8%, 1.6%, 3.0%, and 4.5%, and three methods of application were compared. Methods of application were 1) cuttings treated with solutions containing IBA, captan, benomyl, and streptomycin applied as a one minute soak or 2) as a post plant drench or 3) cuttings soaked for one minute in a solution of captan, benomyl and streptomycin and then dipped into IBA + talc mixture. After the treatments were applied, the cuttings were placed on a mist bench for three weeks. Visual shoot ratings were made weekly and visual root ratings were made at three and four weeks after treatments were applied. Root dry weights were determined. Results indicated the one minute soak in a captan, benomyl, and streptomycin solution then dipped in 0.8% IBA + talc consistently resulted in a higher quality rooted cutting.

ABSTRAK Dalam upaya pengembangan nilam (Pogostemon cablin) di daerah yang jaraknya jauh dari kebun induk, pengadaan benih nilam yang berkua- litas menjadi masalah yang serius, karena bibit akan cepat mengalami penurunan kualitas selama transportasi. Untuk itu dilaksanakan penelitian yang bertujuan untuk mengetahui pengaruh lama simpan setek berakar nilam terhadap pertumbuhan. Percobaan dilaksanakan di rumah kaca Balai Penelitian Tanaman Rempah dan Obat (Balittro) dari bulan April – Agustus 2004. Percobaan disusun dalam rancangan petak terbagi (RPT) dengan 3 ulangan. Petak utama (main plot) adalah 2 jenis setek nilam yaitu: (1) setek berdaun dan (2) setek tidak berdaun. Anak petak (sub plot) adalah lama penyimpanan setek yaitu: (1) setek langsung ditanam (kontrol), (2) setek disimpan 1 hari, (3) setek disimpan 3 hari, (4)setek disimpan 5 hari dan, (5) setek disimpan 7 hari. Pengamatan dilakukan sejak tanaman berumur 2 minggu sampai tanaman berumur 8 minggu. Parameter yang diamati meliputi pertumbuhan tanaman (tinggi, jumlah daun dan jumlah tunas), bobot kering (batang, daun, akar). Hasil perco- baan menunjukkan bahwa persentase hidup setek nilam berakar (setek berdaun dan setek tidak berdaun) masih 100% setelah disimpan selama 7 hari. Hampir dari seluruh parameter pertumbuhan (tinggi tanaman, jumlah cabang, jumlah daun) yang diamati menunjukkan bahwa pertumbuhan bibit setek berdaun lebih baik dibandingkan dengan setek yang tidak berdaun. Kata kunci : Nilam, Pogostemon cablin Benth, bibit, setek berakar, penyimpanan, pertumbuhan, Jawa Barat ABSTRACT Effect of storage periods of rooted cutting on the growth of patchouli (Pogostemon cablin Benth) Providing high quality of patchouli (Pogostemon cablin Benth) seedlings is necessary to support the development of patchouli plants. In the new developing area transportation become serious problems (high cost transportation), therefore some alternative solution is reducing the transportation cost without reducing the quality of the seedlings. Base on the problems, this experiment was conducted. The objective of this experiment was to study the effect of storage periods of rooted cuttings on the growth of patchouli plant. The experiment was conducted in the green house of Indonesian Spice and Medicinal Crops Research Institute (ISMECRI), from April to August 2004. The experiment was arranged in a split-plot design with 3 replications. The main plot was 2 kinds of cutting there were: (1) leaf cutting and (2) non leaf cutting. The sub plot was 5 different storage periods, there were: (1) control (no storage), (2)1 day storage, (3) 3 day storage, (4) 5 day storage, (5) 7 day storage. The variables observed were plant growth (plant height, number of leaves and number of shoots), dry weight of stems, leaves and roots. The results of experiment indicated that after 7 day storage, rooted cuttings of patchouli were still 100% viable. The growth of patchouli from leaf cutting was significantly different from non leaf cutting. Patchouli plant from leaf cutting produced higher plant height, number of leaves, number of shoots and dry weight of plants compared to those of patchouli plants from non leaf cuttings. Storage period significantly affected the height of plants however it did not significantly affected the number of leaves, number of shoots and dry weight of plants.

Container-grown rooted stem cuttings from 13 eastern white pine (Pinusstrobus L.) clones were paired with open-pollinated bare-root seedlings to compare growth through age 8 years of the two stock types. Before planting, measures of root system quality (number of roots per cutting, root distribution, and weighted root score) were recorded for each ramet to relate growth to initial root system quality. Rooted cuttings had higher survival than seedlings through year 8, 78 vs. 68%, respectively, but the difference was not statistically significant. Rooted cuttings were significantly shorter than seedlings after age 4 years, with differences between stock types increasing in magnitude through year 8. Measures of root system quality of rooted cuttings were not significantly correlated with survival or growth at any age.

The traits of vegetative parts (the length of the overground part of the cutting (shoot), the length of the underground part of the cutting (rhizome), the volume of the overground part of the cutting (shoot), the volume of the root system, the weight of the cutting (plant), and absolute cover area) for cuttings of five Sedum species (S. ewersii Ledeb., S. spathulifolium Hook. 'Cape Blanco', S. kamtschaticum Fisch. 'Variegatum', Sedum spurium M. Bieb., S. rupestre L.) were determined. The plants were cultivated for 86 days on a low roof (height = 6 m), in a soil mixture in 7-liter containers with a substrate height of 7 cm. The percentage of rooted cuttings reached 100% for S. ewersii, S. kamtschaticum 'Variegatum', S. spurium, S. rupestre and 66 % for S. spathulifolium 'Cape Blanco'. The highest ability to create absolute substrate cover was noted for species with creeping stems and flattened succulent leaves – S. kamtschaticum 'Variegatum' and S. spurium. This index was slightly lower for a species with vertical stems and stiff pointed, succulent leaves (S. rupestre), and plants with decumbent stems, that bear only the terminal rosettes of leaves (S. ewersii). The ability to substrate consolidation was not significantly different for S. ewersii, S. kamtschaticum 'Variegatum', S. spurium. Root development was lower for S. rupestre and very weak for S. spathulifolium 'Cape Blanco'. The results support planting S. ewersii, S. kamtschaticum 'Variegatum', S. rupestre, S. spurium with fresh harvested cuttings without previous rooting. Cuttings of S. spathulifolium 'Cape Blanco' increased their mass and projective cover slowly and required rooting before planting in a green roof
