Learn which trees are “true to seed” and which need grafting to produce. Acknowledgements: A special thanks to Hawaiian Sanctuary, County of Hawaii Research and Development and all others involved to make these classes a reality! We are still looking for support to complete and enhance this amazing FREE program. Please give what you can: hawaiiansanctuary.com/donate Introduction: Different plants require different methods of propagation. Propagation from Seed: Planting seeds: As a general rule for planting depth, plant seeds 2.5 times their width. Keep soil moist but not waterlogged. Potting soil has ideal drainage and moisture retention and is free from weed seeds and diseases. Direct seeding: Fast growing garden plants (often with larger seeds) are usually planted directly into their permanent location. For example, beans, pumpkin, radish, Seed in nursery: Plants that are slow growing in the begining may be easier to start in 3-4 in. pots in the nursery and then planted out when about 6 in. tall. Ex. kale, tomatoes, eggplant, peppers, or if fruit trees potted into bigger pots till they are 1 to 3 ft tall. Planting fruit trees from seed: Many varieties of tropical fruit trees seeds may die if allowed to dry out. Planting seeds as quickly as possible is a good rule of thumb.

  • 37 Vegetatively Propagating Forest Trees
    Monteuuis O Vegetatively propagating forest trees Monteuuis O CIRAD-BIOS, UMR AGAP, TA A-108/03, Avenue Agropolis, 34398 Montpellier Cedex 5, France. [email protected] Abstract Propagation by seeds gives rise to individuals which are all genetically different from each other. By contrast, asexual or vegetative propagation consists in duplicating, theoretically unlimitedly, genotypes while preserving through mitotic divisions their original genetic make-up, and consequently all their individual characteristics. This is essential to ensure the transfer of economically important traits which are under non-additive control. Vegetative propagation can be applied to any individual that does not produce fertile seeds, either because it has not entered the mature reproductive stage yet, or due to unfavorable environmental conditions. Its usefulness is obvious for research as well as for operational activities, depending on the ultimate objectives and on the most suitable strategies to meet the goals. Conventional nursery techniques and in vitro culture can be used for vegetatively propagating forest tree species. The respective pros and cons of these various vegetative propagation methods, which can synergistically complement each other, are considered, mainly from an operational viewpoint. Species characteristics and cost effectiveness must be taken into account for applications while pondering the real advantages and limitations of vegetative versus seed- based propagation strategies in the general context of forest tree plantations. Keywords:axillary budding, clone, cuttings, grafting, in vitro culture, organogenesis, self-rooted plants, somatic embryogenesis. Foreword The 4th conference of the IUFRO working unit 2.09.02 has recently given us the opportunity to discuss the last advances of somatic embryogenesis (SE) and other vegetative propagation (VP) technologies applied to forest tree species.

  • Weed Control in Mist-Propagated Sitka Spruce (Picea Sitchensis (Bong.) Carr.) Cuttings by D.V Clay, F.L
    Weed control in mist-propagated Sitka spruce (Picea sitchensis (Bong.) Carr.) cuttings by D.V Clay, F.L. Dixon and I. Willoughby SUMMARY: When Sitka spruce is propagated in polytunnels, weed infestations can potentially interfere with the growth of cuttings and impact on general crop husbandry, as well as acting as a seed source to infest other parts of a nursery. Hand weeding can be carried out, but it is labour intensive. The use of herbicides might prove a cheaper option, but there are currently no products approved for Sitka spruce production in polytunnels in the UK. Hence in the work reported here, four weed species, hairy bitter-cress, annual meadow-grass, groundsel and common chickweed were grown in close proximity to Sitka spruce cuttings. The susceptibility of these species to the herbicides propyzamide, napropamide, simazine and propaquizafop (the latter on annual meadow-grass only) was assessed. Propyzamide controlled chickweed when applied pre- or post-weed–emergence, and annual meadow-grass when applied pre- and post-weed-emergence. Propaquizafop controlled annual meadow-grass when applied post-weed-emergence and prevented seeding when sprayed post-flushing. Napropamide and simazine were not effective in preventing seeding of any weed species. Although the herbicides generally did not appear to have any adverse effect on the growth of Sitka spruce cuttings, further work is needed to confirm herbicide selectivity, particularly regarding adventitious root formation. Competition from weeds did not appear to affect the early shoot growth of cuttings. Whilst these results indicate that propaquizafop, and possibly propyzamide, may have the potential for safely controlling some annual weed species, in the short term good nursery hygiene, coupled with hand weeding where necessary, remains a more practical approach than using herbicides within polyhouses.

  • Propagation Protocol for Production of Carex Mertensii Prescott Ex Bong
    Protocol Information USDA NRCS Corvallis Plant Materials Center 3415 NE Granger Ave Corvallis, Oregon 97330 (541)757-4812 Corvallis Plant Materials Center Corvallis, Oregon Family Scientific Name: Cyperaceae Family Common Name: Sedge Scientific Name: Carex mertensii Prescott ex Bong. Common Name: Merten's sedge Species Code: CAME6 Ecotype: Mount Rainier National Park, 4,200 to 4,400 ft elev. General Distribution: Pacific Northwest and northern California, north to Alaska, Idaho and Montana. In our collection, plants were found in open areas growing with Lupinus latifolius and other forbs along roadsides. Propagation Goal: Seeds Propagation Method: Seed Product Type: Propagules (seeds, cuttings, poles, etc.) Stock Type: Seed Time To Grow: 2 Years Target Specifications: Clean seed with no noxious weeds; seed weights averaged 1,565,500 seed / lb. Propagule Collection: Seeds hand-stripped from individual plants into cloth or paper sacks; or seed heads clipped with hand pruners where plants were more abundant. Propagule Processing: Dried seed heads very chaffy; if whole heads are collected, seed can be threshed using a geared-down hammermill with 1/16th screen; run through an oat dehuller one or more times; then through an office clipper (air screen machine) with #8 top screen, 1/20" round bottom screen, and medium air flow. Some workers at the PMC found that chaff was 1 irritating to skin and eyes: gloves, goggles, and dust masks were needed especially to clean larger quantities of seed. Pre-Planting Treatments: None - our lots showed 53 to 63% germination. Growing Area Preparation/ Fine, weed-free seed bed. Due to lack of available Annual Practices for Perennial Crops: herbicides to suppress weedy grasses, our best results were obtained by carbon-banding.

Archbold Received: 1 December 2015; Accepted: 18 February 2016; Published: 30 December 2016 Abstract: Most often, organic farming focuses on the improvement of management practices such as nutrient application and pest control, and very seldom deals with variety improvement or breeding. Because it has been dependent on commercially-available varieties developed under conventional high-input methods, traits are expressed resulting in low yields that are commonly attributed to organic farming practices rather than to the adaptability of the cultivar to the system. A research program in the Philippines involving several regions and institutions has pioneered in the evaluation and improvement of varieties through breeding under low-input organic conditions. After making several crosses, pedigree selection, replicated yield and on-farm trials, promising and potential varieties were developed and identified in squash, cucumber, lettuce and yardlong bean. The most promising yield advantages over the respective check varieties ranged up to 47% in squash, 31% in yardlong bean, 42% in lettuce, and 43% in cucumber.

Cultivars from Shoot and Leaf Culture Fikadu Kumsa Department of Biology, College of Natural and Computational Science, Ambo University, Ethiopia Abstract Invitro regeneration is aseptic culture of cells, tissues, organs or whole plants under controlled nutritional and environmental conditions. Grapevine ( Vitis vinifera L.) is one of the most widely distributed fruit crops in the world. Conventional method of grapevine propagation is time consuming and allows disease transmission. A planted grape vine needs four to five years to be a propagation material by cutting, due to its long juvenility period. Therefore, the establishment of efficient in vitro regeneration is too much needed. The optimal levels of growth regulators and light conditions on callus induction and organogenesis of in-vitro cultured grapevine were assessed. Accordingly, maximum calluses and shoots were produced by using medium supplemented with different concentrations of growth regulators (BAP, IBA, TDZ and NAA) as alone or in combinations. For successful production of propagules, the occurrence and effect of in vitro shoot vetrification /hyperhydricity/were assessed. From the tested different concentrations of BAP and agar, the best mean numbers of vetrification free shoots were obtained at 0.5 mg/l BAP in 7.5g/l agar for both cheninblanc and canonannon cultivars.

  • Chapter 3: Propagation and Outplanting
    CHAPTER 3: PROPAGATION AND OUTPLANTING 3.1 INTRODUCTION Propagation and outplanting are necessary objectives toward the goal of achieving stable and sustainable populations for PTA’s listed species. The three areas of focus to meet these objectives have been genetic storage, germination and propagation tests, and rare plant reintroduction and augmentation. Genetic Storage: Seed collection protocols developed by the Center for Plant Conservation (CPC 1991) and the Mākua Implementation Team (US Army, Hawai`i 2002) were followed. These protocols include: 1.) collect from 50 individuals per population when possible; 2.) for populations with less than 50 individuals, collect from all individuals; 3.) collect approximately 20% of seed on existing plants unless there are less than 10 individuals remaining and the population is declining precipitously, in which case more seed may be collected in order to preserve genetic material. Germination and Propagation Tests: Germination and propagation tests were continued for Hedyotis coriacea, Neraudia ovata, Solanum incompletum, and Schiedea hawaiiensis. These tests complement work already completed and will work towards completing PTA propagation protocols for all listed species. Rare Plant Reintroduction and Augmentation: The introduction of rare plant populations to sites within and outside of PTA’s boundaries via outplanting was begun. The species and numbers outplanted were determined by general guidelines in the Scope of Work, site characteristics and greenhouse stock. Augmentation was most often implemented through site management such as fencing, weeding and rodent control. 3.2 GENETIC STORAGE INTRODUCTION Seeds provide a storehouse for genetic diversity. Propagule collection and protective storage are essential components of rare plant conservation. Two methods of germplasm preservation (seeds and standard plantings) are utilized by PTA’s Natural Resources Staff (NRS) for conserving listed species.
