Armazenamento do grão de pólen de cebola (Allium cepa L.)

Experimentos foram conduzidos no Laboratório de Melhoramento Genético da Embrapa Clima Temperado, em Pelotas, RS, com o objetivo de avaliar, in vitro, o potencial de armazenamento dos grãos de pólen de cebola da cv. Petrolini, em diferentes condições por dois anos. Para tanto, avaliou-se a percentagem de germinação do grão de pólen após um e dois anos de armazenamento em criotubos, acondicionados em nitrogênio líquido (-196ºC), e em frascos de vidro acondicionados no interior de dessecador contendo ácido sulfúrico e mantidos em freezer (-18ºC). O pólen conservado por um ano em nitrogênio líquido foi então transferido para um refrigerador, registrando-se a percentagem de germinação após 10, 15, 20 e 30 dias de permanência neste. O armazenamento em nitrogênio líquido foi o melhor ambiente para a conservação dos grãos de pólen durante dois anos. As amostras armazenadas, por um ano, em nitrogênio líquido, que foram transferidas para refrigerador, conservaram-se viáveis por até dez dias.

Varareittisuunnitelma Pohjois-Pohjanmaan ELY-keskuksen alueen itäosan kantateille : Kantatiet 75, 76, 78, 81 ja 89

Pääteillä esiintyvien häiriöiden, kuten onnettomuuksien, tietöiden, tapahtumien ja poikkeuksellisten ruuhkatilanteiden varalle tarvitaan varareittejä, joille liikenne voidaan häiriön sattuessa ohjata joko kokonaan tai osittain. Varareitit ja niiden opastus tulee olla ennalta suunniteltuja, jolloin niiden käyttöönotto sujuu häiriötilanteessa mahdollisimman vaivattomasti eri viranomaisten yhteistyönä. Häiriötilanteiden hallinnassa paitsi suunnitellut varareitit ja niiden liikenteen ohjaus, myös tiivis yhteistyö eri viranomaisten välillä on oleellista tilanteen sujuvan hoitamisen kannalta. Tässä raportissa on esitetty Pohjois-Pohjanmaan itäosan kantateille liikenteen häiriötilanteissa käytettävät varareitit, häiriöpaikalla tapahtuvan liikenteenohjauksen periaatekuva sekä varareittien liikenteenohjaussuunnitelmat. Suunnittelualueella on, kuten pääsääntöisesti koko Suomen tieverkolla, varsin vähän lyhyitä ja aina kaikelle liikenteelle soveltuvia varareittejä. Tämän vuoksi suunnitelmassa määritettiin varsinkin raskaan liikenteen tarpeita ajatellen myös pidempiä varareittejä. Pidemmille varareiteille liikennettä ohjattaessa korostuu tiedotuksen ja liikenteenohjauskaluston tärkeys. Varareitin aktivoinnissa ja liikenteenohjauksen järjestämisessä korostuu yhteistyö liikenneviraston tieliikennekeskuksen kanssa. ELYkeskus vastaa kustannuksista, urakoitsijan kanssa tehdyn sopimuksen mukaisesti, jotka syntyvät urakoitsijan toiminnasta häiriöhallintatilanteen purkamisessa

Interactions of onion (Allium cepa) and yellow wax bean (Phaseolus vulgaris) in monoculture and intercropping with weeds, Chenopodium album and Amaranthus hybridus

Intercropping systems are seen as advantageous as they can provide higher crop yield and diversity along with fewer issues related to pests and weeds than monocultures. However, plant interactions in intercropped crop species and between crops and weeds in these systems are still not well understood. The main objective of this study was to investigate interactions between onion (Allium cepa) and yellow wax bean (Phaseolus vulgaris) in monocultures and intercropping with and without the presence of a weed species, either Chenopodium album or Amaranthus hybridus. Another objective of this study was to compare morphological traits of C. album from two different populations (conventional vs. organic farms). Using a factorial randomized block design, both crop species were planted either in monoculture or intercropped with or without the presence of one of the two weeds. The results showed that intercropping onion with yellow wax bean increased the growth of onion but decreased the growth of yellow wax bean when compared to monocultures. The relative yield total (RYT) value was 1.3. Individual aboveground dry weight of both weed species under intercropping was reduced about 5 times when compared to the control. The poor growth of weeds in intercropping might suggest that crop diversification can help resist weed infestations. A common garden experiment indicated that C. album plants from the conventional farm had larger leaf area and were taller than those from the organic farm. This might be associated with specific evolutionary adaptation of weeds to different farming practices. These findings contribute to the fundamental knowledge of crop-crop interactions, crop-weed competition and adaptation of weeds to various conditions. They provide insights for the management of diversified cropping systems and integrated weed management as practices in sustainable agriculture.

HG 78.45-78.55

Coarse sediment with grains ranging from small to large . Clast shape ranges from sub-angular to sub-rounded. Grain crushing is common throughout the sample, with many grains being crushed into one another. A few lineations and rotation structures can also be seen throughout.
