Va Mycorrhizal Fungi

Abstract The benefits from root colonization by mycorrhizal fungi are thought to be highest when colonization occurs as early as possible during plant growth. We assessed whether addition of VA mycorrhizal fungi (VAMF) inoculum into rooting medium during cutting propagation would increase the quantity of rooting and the quality of rooted cuttings for five different cultivars of miniature roses (Rosa spp.). Four weeks after cuttings were stuck, the number of cuttings with roots for two cultivars that normally take longer to root, increased with addition of VAMF inoculum into the rooting medium. The combination of hormone treatment (IBA and NAA) and VAMF inoculum in the rooting medium increased the number of rooted cuttings and the number of roots per cutting for three cultivars when compared to cuttings that only received hormone treatment. Increases in root initiation and root growth of cuttings rooted in medium containing VAMF inoculum were not always associated with increased levels of root colonization by VAM fungi. Our results indicate that although adding VAMF inoculum into the rooting medium does not always increase root initiation, in some cultivars the combination of VAMF inoculum and rooting hormones can increase root initiation and potentially increase the quality of rooted cutting produced.

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

The difficulties of nurserymen and producers of plantains in Côte d’Ivoire are the high mortality rate of seedlings and the delays of growth in the field. The aim of this study is to improve quality and agronomic performance of plantain seedlings produced by PIF technique (plantain seedlings production based on macropropagation). The plantain shoot bulbs were inoculated before being placed in the germinator and seedlings from germinator were inoculated again during the weaning phase at nursery with AMFs (Rhizophagus intraradices). Root mycorrhizal colonization, growth parameters such as girth, height, total leaf area, biomass and entry into production were measured in nursery and on the field. The results showed that the root colonization rate of the plants inoculated with R. intraradices inoculum was higher (30.59%) than that of the native arbuscular mycorrhizal fungi (2.78%). All inoculated plants survived while non-inoculated plants had 27.69% of mortality rate. Inoculated plants had higher growth than non-inoculated plants. The organs of inoculated plants also had higher biomass than non-inoculated plants. Eleven months after planting, nearly 50% of the inoculated plants had started production, while only 5.67% of the non-inoculated plants had started production. Mycorrhization improved the vigor and vegetative growth of plantain seedlings. It could therefore be used as a solution for a sustainable plantain culture.

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.

Hardwood cuttings of kinnikinnick (Arctostaphylos uva-ursi `Massachusetts') were inoculated with three different types of inoculum of mycorrhizal fungi to determine whether addition of mycorrhizal inoculum into the rooting substrate during cutting propagation increases rooting or root growth, or alters the time for rooting. Cuttings, treated or untreated with rooting hormone prior to sticking into the rooting substrate, were inoculated with either inoculum of an arbuscular mycorrhizal fungus (AMF), hyphal inoculum of an arbutoid mycorrhizal fungus (E), or inoculum consisting of colonized root fragments of kinnikinnick (R). Cuttings were placed under mist in a greenhouse with no bottom heat and harvested 35, 56, and 84 days after sticking. Using AMF inoculum in the rooting substrate did not enhance rooting of cuttings, while adding the R or E inoculum to the rooting substrate increased root initiation compared to non-inoculated cuttings. Cuttings inoculated with either the R or E inoculum had greater root initiation than non-inoculated cuttings 56 and 84 days after sticking. When treated with rooting hormone, cuttings inoculated with the E or R inoculum had longer roots and a greater root biomass than non-inoculated cuttings. Mycorrhizal colonization of roots was similar or greater when cuttings were inoculated with the E inoculum than with the R inoculum and application of rooting hormone generally increased root colonization. The use of inoculum composed of root fragments from kinnikinnick during cutting propagation does not appear to be more beneficial than use of hyphal inoculum from a known arbutoid mycorrhizal fungus.

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.

In a commercial nursery propagation system for hick's yew (Taxu×media `Hicksii'), we assessed whether or not the addition of inoculum of the vesicular-arbuscular mycorrhizal fungus (VAMF) Glomus intraradices into the rooting substrate during cutting propagation increased rooting, and how the quantity of inoculum influenced rooting. At 15 and 22 weeks (108 and 156 d) after cuttings were treated with root hormones and stuck, root initiation was higher on cuttings stuck in the rooting substrate containing VAMF inoculum. Increasing the quantity of inoculum in the rooting substrate increased root growth during the early stages of rooting. However the highest level of inoculum tested increased adventitious root initiation without increased root growth. Our results indicate that if VAMF inoculum is used during propagation from cuttings, there are optimal levels required to alter the initiation and growth of roots. For hick's yew, 1:100 or 2:100 (by volume) rates of G. intraradices in the rooting substrate increased the number of primary roots and growth of adventitious roots on cuttings above that achieved by using rooting hormone alone.

The roots of most plants host diverse assemblages of arbuscular mycorrhizal fungi (AMF), which benefit the plant hosts in diverse ways. Even though we understand that such AMF assemblages are non-random, we do not fully appreciate whether and how environmental settings can make them more or less predictable in time and space. Here we present results from three controlled experiments, where we manipulated two environmental parameters, habitat connectance and habitat quality, to address the degree to which plant roots in archipelagos of high connectivity and invariable habitats are colonized with (i) less diverse and (ii) easier to predict AMF assemblages. We observed no differences in diversity across our manipulations. We show, however, that mixing habitats and varying connectivity render AMF assemblages less predictable, which we could only detect within and not between our experimental units. We also demonstrate that none of our manipulations favoured any specific AMF taxa. We present here evidence that the community structure of AMF is less responsive to spatio-temporal manipulations than root colonization rates which is a facet of the symbiosis which we currently poorly understand.
