Amaryllidaceae F, R W C W C W W W Slim leaved onion Harmonization and Impact Statement: Allium amplectens is not in the Federal Seed Act Regulations, the Canadian M & P, or the ISTA Rules. This is a commercially marketed species; therefore, adding working weights and a pure seed unit definition to the AOSA Rules will standardize seed testing procedures among laboratories. This species is listed in Volume 3 Uniform Classification of Weed and Crop Seeds as a weed. Supporting Evidence: Allium amplectens is a bulbiferous native species to California, Orgon, Washington, and British Columbia. Plants produce 10-50, pale pink to white, star-shaped flowers per globe-shaped inflorescence from April to July. Native pollinators love the showy long-lived flowers. Freely reseeding, large bunches of these flowers are colorful for many weeks and serve as a key nectar source for Fenders Blue Butterfly. This species is listed in Volume 3 Uniform Classification of Weed and Crop Seeds as a weed under spp. class and as weed under all contaminating classifications. Since A. amplectens seed is sold commercially as an ornamental and a pollinator attractant, as well as being a native plant, it should be place under spp. class ‘F’ and ‘R’ and when found as a contaminant in a ‘F’ or ‘R’ kind of seed the authors recommend it be classified as other crop. Seed counts were conducted at the Agri Seed Testing Lab on eleven seed lots received since 2008. The seed count method was in accordance to AOSA Rules, Section 13: Non-mechanical Seed Count and Working Weight Determinations (Figure 1). Refer to Appendix 1 of this proposal for replicate data.

Purity working weights for eleven commercial seed lots of Allium amplectens, narrowleaf onion, based on non-mechanical seed counts. The red line indicates the average purity working sample weight across all eleven seed lots is 4.031 grams. Results of the statistical analysis are shown in Table 1. Methodology for the analysis: 1. Each set of data per seed lot (usually 8 replications) was checked for normality of distribution (Shapiro-Wilk test for normality, p 0.05; ranks not averaged for tied values). 2. For non-normally distributed data sets of a single seed lot, an outlier test was used to identify a single outlier (Grubbs’ test, p 0.05). 3. Data was rechecked after removing a single outlier. Revised data sets (after removing the outlier) were used in the final determination of average weight of 100 seeds. If removing a single outlier still resulted in non-normally distributed data, the data set for that seed lot was considered unreliable and results excluded from further data analysis. 4. Means of each lot were then used to calculate the overall mean weight of 100 seeds for that species and a 95% confidence interval for the mean. 5. The same means were also checked for normality of distribution and presence of outliers. However, no attempt was made to discard outliers at this stage. If the outlier replicate average can be ascribed to errors in data collection, then the data should be discarded. However, if the outlier is due to natural variation (e.g., genetic, varietal or cultural differences), discarding the data is not recommended. This is a judgment call unrelated to statistical analysis results. Table 1. Species mean seed weight and confidence intervals of data checked for normality of distribution and presence of outliers.

Presence of outliers verified using Grubbs’ test (p 0.05). 4 Each seed lot was tested for normality after outlier was removed. If data set of a seed lot was still not normally distributed after removing outlier, that seed lot was excluded from analysis.

    HEREDITY VOLUME 20 PART 3 AUGUST 1965 GENETIC SYSTEMS IN ALLIUM III. MEIOSIS AND BREEDING SYSTEMS S. VED BRAT Botany School, Oxford University Received12.11.65 1. INTRODUCTION REGULATIONof variability in a species is mainly determined by its chromosome behaviour and reproductive method. Their genotypic control and adaptive nature has been pointed out by Darlington (1932, '939) and by Mather (i4). Their co-adaptation is vita! for the genetic balance of a breeding group. Consequently, a forced change in the breeding system of a species upsets its chromosome behaviour during meiosis as in rye (see Rees, 1961) or it may lead to selection for a change in chromosome structure securing immediate fitness as in cockroaches (Lewis and John, 1957; John and Lewis, 1958). In nature, coordination between chromosome structure and behaviour, and the breeding system fulfils the need for compromise between long term flexibility and immediate fitness. This is achieved through the control of crossing over within the chromosomes and recombination between them. The sex differences in meiosis, however, have a special significance in this respect and I have discussed the same earlier (i965b). Thus, the meiotic mechanism provides recom- bination within the genotype and the breeding systems extend the same to the population. The present study is an attempt to find out the working correlations between the two components of the genetic systems in the genus Allium. 2. MATERIALSAND METHODS Mostof the Allium species used in the present studies were obtained from Botanic Gardens but wild material was examined where possible (table i, Ved Brat, x 965a). Meiosis was studied from the pollen mother cells after squashing in acetic orcein (Vosa, i g6 i).

  • Hell's Half Acre, Lava Cap Wildflower Field
    Lava Cap Wildflower Fields by Karen Callahan1 and Jennifer Buck-Diaz2 Lava caps provide a special botanical heaven in the Sierra Nevada foothills, where acres of brilliant wildflowers bloom in the spring and linger into the summer. These distinctive open habitats have shallow soils underlain by an ancient solidified volcanic mudflow, or lahar. This cement-like layer, along with gentle slopes, allows rainfall to collect in depressions before slowly draining off or evaporating. Showy, mostly native, annual plants thrive here with little competition from invasive species that have a low tolerance to restricted drainage and shallow soils. Hell’s Half Acre in Nevada County is one prime example of lava cap habitat in the north-central Sierra Nevada (featured on the cover of this issue). This 70-acre area is located about 1.5 miles northwest of Grass Valley (elevation 2,600 feet) and consists of open, rocky flats dominated by grasses and wildflowers, surrounded by foothill pines (Pinus sabiniana) and manzanita (Arctostaphylos viscida) chaparral. The lava cap supports over 100 species of native plants, including at least 10 species typical of vernal pools that occur in a matrix with upland plants. In addition, rare and uncommon plants such as Sanborn’s onion (Allium sanbornii var. sanbornii), Lemon’s stipa (Stipa lemmonii var. pubescens), Pratten’s buckwheat (Eriogonum prattenianum var. prattenianum), and Orcutt’s quillwort (Isoetes orcuttii) are found Allium amplectens and Festuca microstchys.

Slim-leaf onion (Allium amplectens) is a native species in Garry Oak ecosystems and is Blue listed in British Columbia as a vulnerable species to focus on for preventative conservation. The population of Slim-leaf Onion in Oak Haven Park was surveyed and found to be comparable in size with other populations in BC, and adds to the conservation value of the Park. Removal of broom (Cytisus scoparius) was undertaken in the vicinity of the Slim-leaf Onion population to preserve the habitat quality and open up more Garry Oak meadow for possible expansion of the Slim-leaf Onion Population. Recommendations for future health of the Population are the active discouragement of a walking pathway which tramples the plants, and continuing removal of Scotch Broom which will re-grow near the population site. Introduction Oak Haven Park Site location and description Oak Haven Park in Central Saanich (Figure 1) is within the coastal Douglas-fir biogeoclimatic zone (CDFmm), which covers an area including the southwest coast of Vancouver Island, several gulf Islands, and a sliver of the sunshine coast on the mainland of BC (Meidinger and Pojar 1991).
