  • Ethylene in Floriculture
    technically speaking BY ERIK RUNKLE Ethylene in Floriculture Ethylene is a hormone that influences growth and development of plants throughout their life cycle. It is a colorless gas that is active at very low concentrations, even at parts per billion (which is 0.001 part per million). For most crops, ethylene inhibits extension growth, promotes branching, stimulates leaf senescence, and aborts flowers and flower buds. Ethylene can be a harmful contaminant in greenhouses, as well as during shipping of young plants to greenhouses and finished (flowering) plants to the retail market. However, there are situations when ethylene can elicit desirable responses in greenhouse crop production. This article summarizes inadvertent and intentional ethylene exposure to floriculture crops. Unwanted ethylene in greenhouses. Plants naturally produce ethylene, but this alone is not a concern Figure 1. If growth of plants is stunted, flowering is delayed, in greenhouses because concentrations are so low. or leaves start to twist or curl, ethylene contamination may be Ethylene contamination usually occurs when there is the problem. Check unit heaters to ensure adequate oxygen is insufficient oxygen provided to unit heaters (resulting in provided for complete combustion of fuels, and that the exhaust is incomplete combustion of fuels), or when the exhaust is sufficiently ventilated. inadequately vented. The effects of ethylene depend on the concentration, duration of exposure, temperature, State) as well as by private consultants has shown that Collate is and species. At a relatively high concentration, such as effective at lower drench rates, such as 20 to 40 ppm on bedding 1 or 2 ppm, symptoms of ethylene exposure are quite plants and 200 to 250 ppm on potted daffodils.

Jill is well known in the international world of Hibiscus and has an in depth knowledge of the Hawaiian species. H. clayi / ©David Eickhoff H. kokio / ©Bill Schmidt Recent University of Hawai'i genetic DNA analysis of the various endemic (native) Hawaiian hibiscus has determined that there are four unique species of Hawaiian reds: H. clayi, H. kahilii, H. kokio, and H. saintjohnianus. Hawaiians refer to all of these as Koki'o 'ula'ula.

Hawaiians call all of these Koki'o ke'oke'o. Many think that these have all evolved from a single seed brought by a bird. HIBISCUS INTERNATIONAL 2 H. brackenridgei / ©KarllM We have another endemic species of Hibiscus: H. brackenridgei, known in Hawaiian as Ma'o Hau Hele. It can sometimes become a small tree growing up to 30 feet tall. The fuzzy leaves have toothed edges, 3, 5, or 7 lobes, and are up to 6 inches long/wide. Most of these Hibiscus have become quite rare in the wild, and several are classified as endangered.

    BIOLOGY | GHOST | FLOWERS | The genes of Hawaiian plants, extinct for more than a century, have been brought back from the dead. Today we can smell their scents By Rowan Jacobsen Photographs by Floto + Warner 30 Scientific American, ebruaryF 2019 BACK FROM THE BRINK: The Wynberg conebush (l eft ) went extinct in 1806, and Maui’s mountain hibiscus (r ight ) followed in 1912. But their DNA has been recov­ ered, and some rejuvenated scent genes are once again producing fragrances. The hibiscus, sniffed by people for the first time in more than a century, evokes bark and juniper, with hints of citrus and thyme. February 2019, ScientificAmerican.com 31 Journalist Rowan Jacobsen is author of several books, such as Shadows on the Gulf (Bloomsbury, 2011) and The Essential Oyster (Bloomsbury, 2016), and many magazine articles. He was a 2017–18 Knight Science Journalism Fellow at the Massachusetts Institute of Technology. n 1912, on the ancient lava fields of haleakala– on the hawaiian island of Maui, a single tree stood near death. Fifteen feet tall, its bark encrusted with lichens, it was down to its last flower. The Hawaiians called this tree hau kuahiwi, the mountain hibiscus. Unlike the more familiar Hawaiian hibiscus, which grows in moist valleys and opens wide in a welcom- ing aloha, the mountain hibiscus grew only on the dry, well-drained lava fields of Hawaii’s volcanoes. The plant unfolded only two of its five hibiscuslike petals, keeping the rest closed in a demure, curved tube designed for Maui’s honeycreepers—nectar-eating Isongbirds with curved bills that were its favored pollinators.
