  • Season Extenders in the Flower Garden by Pat Holloway and Pat Wagner
    University of Alaska Fairbanks School of Natural Resources and Extension Georgeson Botanical Notes No. 57 (1993) - Revised 2014 Season Extenders in the Flower Garden by Pat Holloway and Pat Wagner No one gardening in Alaska needs to be reminded that the growing season is very short, especially after the summer of 1992 when the frost-free season at the Garden extended only from May 16 to September 10, and the snow-free season was the shortest ever recorded. Every year we survey the Garden after our first hard frost to identify flowers that still look good and can provide a bit of color even as the days get shorter and we begin to anticipate the first snowfall. On the following page is a list of annuals and perennials that sur- vived the first severe frost on September 10 with an overnight low of 13°F (-10°C). In some instances, only the foliage survived, but they still provided a bit of green color at season’s end. Prior to September 10, temperatures at or slightly below 32°F (0°C) were recorded on three dates, but damage was negligible. Although the flower beds are located fairly close together on a gently sloping hillside, we noticed some differences in damage in the various beds. Flowers in one bed survived the frost, whereas plants of the same species in an adjacent bed were killed. This may be related to differences in cultivars since we did not repeat cultivars in different beds, but it also could be related to slight differences in microclimate from one bed to another.

  • Inbreeding and Inbreeding Depression of Paeonia Decomposita (Paeoniaceae), a Threatened Endemic Plant to China Shi‑Quan Wang*
    Wang Bot Stud (2019) 60:28 https://doi.org/10.1186/s40529-019-0276-8 ORIGINAL ARTICLE Open Access Inbreeding and inbreeding depression of Paeonia decomposita (Paeoniaceae), a threatened endemic plant to China Shi‑Quan Wang* Abstract Background: Small populations are predominantly vulnerable to inbreeding and inbreeding depression (ID). Owing to increased levels of inbreeding on individuals in small populations, ID could decrease the population growth rate, as well as its efective size, and exacerbate the extinction risk. Inbreeding depression remains a crucial area of research in conservation biology, ecology, and evolutionary biology. This study aims to elucidate the reproductive biology, inbreeding, and ID of Paeonia decomposita and to conserve, manage, and improve them better in the future. Results: Paeonia decomposita belongs to a xenogamous category and is partially self‑compatible; moreover, it requires pollinators for seed production. Lately, the occurrence of pollination and pollinator limitations has afected the seed set. Low seed set primarily correlated with an abnormality of meiosis in the pollen mother cell, moderate to low genetic diversity, drought and extreme weather, pollinator limitation, or carpel space limit. One of the primary reasons for endangered mechanism in P. decomposita is the low seed set under natural conditions. The cumulative value of ID was positive, and outcrossed progeny outperformed selfed progeny. Conclusions: Paeonia decomposita requires pollinators to ensure seed production either through autogamy, geito‑ nogamy, or allogamy. It is both allogamous and partially self‑compatible, as well as a successful outcrosser. Inbreeding occurs frequently and results in ID, which imposes a potential threat to the survival of populations.

  • Colonial Garden Plants
    COLONIAL GARD~J~ PLANTS I Flowers Before 1700 The following plants are listed according to the names most commonly used during the colonial period. The botanical name follows for accurate identification. The common name was listed first because many of the people using these lists will have access to or be familiar with that name rather than the botanical name. The botanical names are according to Bailey’s Hortus Second and The Standard Cyclopedia of Horticulture (3, 4). They are not the botanical names used during the colonial period for many of them have changed drastically. We have been very cautious concerning the interpretation of names to see that accuracy is maintained. By using several references spanning almost two hundred years (1, 3, 32, 35) we were able to interpret accurately the names of certain plants. For example, in the earliest works (32, 35), Lark’s Heel is used for Larkspur, also Delphinium. Then in later works the name Larkspur appears with the former in parenthesis. Similarly, the name "Emanies" appears frequently in the earliest books. Finally, one of them (35) lists the name Anemones as a synonym. Some of the names are amusing: "Issop" for Hyssop, "Pum- pions" for Pumpkins, "Mushmillions" for Muskmellons, "Isquou- terquashes" for Squashes, "Cowslips" for Primroses, "Daffadown dillies" for Daffodils. Other names are confusing. Bachelors Button was the name used for Gomphrena globosa, not for Centaurea cyanis as we use it today. Similarly, in the earliest literature, "Marygold" was used for Calendula. Later we begin to see "Pot Marygold" and "Calen- dula" for Calendula, and "Marygold" is reserved for Marigolds.

Fatty acids were identified as fatty acid methyl esters (FAME) by capillary gas-liquid chromatography (GC) and capillary GC- Fourier transform infrared spectroscopy (FTIR). For trienic FAME the use of a cyanopropyl- polysiloxane stationary phase (CP-Sil 88) allowed the separation with high resolution of methyl ester of columbinic acid (trans-5,c/s-9,ds-12 18:3) and gamma-linolenic acid (cis-6,cis-9,cis-12 18:3). The results confirmed the presence of columbinic acid in Thalictrum seed oils, and that of gamma-linolenic acid in A nem one and related species seed oils. The taxonomic subdivision of Ranunculaceae into sub-families and tribes, which resulted from morphological considera­ tions, did not account for the above results. Introduction binic acid (COL) or trans-5,cis-9,cis-12 18:3 Species of the botanical family Ranunculaceae (Bagby et al., 1962; Kaufmann and Barve, 1965; are herbaceous plants bearing dry fruits such as Spencer et al., 1970; Takagi et al., 1983; Wu et al., achenes and follicles.
