| A aclimatização é uma etapa da micropropagação que inspira cuidados, pela dificuldade de transferir com sucesso as plântulas in vitro para a casa-de-vegetação. O objetivo do trabalho foi avaliar a eficiência de substratos à base de coco durante a aclimatização de bastão-do-imperador. As mudas, obtidas de cultivo in vitro, apresentavam, inicialmente, altura média de 6,2 ± 0,4 cm. Foram cultivadas em vasos de polipropileno, permanecendo em viveiro com 70% de luminosidade. Os tratamentos foram: areia, coco em pó, coco desfibrado, coco em pó + areia, coco desfibrado + areia e coco em pó + coco desfibrado. Cinco meses após o transplantio avaliaram-se as variáveis proporção de sobrevivência, altura da parte aérea, massa fresca, número de brotos, massa... |

| 十勝地方におけるラッカセイ生産の可能性を模索するため、帯広畜産大学実験圃場でラッカセイ品種「千葉半立」、「ナカテユタカ」、および「おおまさり」の栽培を行った。栽植方法（直播、あるいは移植）、および栽植密度（標準植：5.1 株/ ㎡、あるいは密植：7.7 株/ ㎡）の組合せによる4 試験区を設け、2016 年5 月23 日にそれぞれの品種の栽培を開始した。茎葉の黄変期に収穫を行い、収量構成要素や子実収量の評価を行った。千葉半立とナカテユタカでは、子実収量に対する栽植方法と栽植密度の効果が認められた。両品種とも移植を行った試験区で直播を行った試験区に比べ収量が高かった。これは、移植を行うことで単位面積当たりの稔実粒数が増加することに起因する。また、両品種とも密植を行った試験区で標準植を行った試験区に比べ収量が高かった。千葉半立は半立ち性、ナカテユタカは立性の草型をもつため光競合を起こしにくく、十勝地方で栽培する場合には都府県の慣行法よりも栽植密度を高めることで土地利用効率が高まり、子実収量が改善されると考えられる。おおまさりでは、子実収量に対して栽植方法の効果のみが認められた。移植を行うことで直播を行った場合に比べ総稔実粒数や1000 粒重が高まり、子実収量が増加した。一方、おおまさりでは子実収量に対する栽植密度の効果が認められなかった。おおまさりは伏性の草型を持つため光競合が起こりやすく、十勝地方においても密植条件下では密度障害が生じ増収につながらないと考えられる。千葉半立とナカテユタカでは、移植・密植の処理組合せによる試験区で、おおまさりでは、移植・標準植、および移植・密植の処理組合せによる試験区でそれぞれ最も子実収量が高く、いずれも子実収量の全国平均（180g/... |

| Some species of seagrasses (e.g., Zostera marina and Posidonia oceanica) have declined in the Mediterranean, at least locally. Others are progressing, helped by sea warming, such as Cymodocea nodosa and the non-native Halophila stipulacea. The decline of one seagrass can favor another seagrass. All in all, the decline of seagrasses could be less extensive and less general than claimed by some authors. Natural recolonization (cuttings and seedlings) has been more rapid and more widespread than was thought in the 20th century; however, it is sometimes insufficient, which justifies transplanting operations. Many techniques have been proposed to restore Mediterranean seagrass meadows. However, setting aside the short-term failure or half-success of... |

| Abstract The type of environment and substrates quality in seedlings production are essential for the production of productive plants under field conditions. In order to determine the best environment and substrate for seedlings production of two tomato cultivars (IPA 06 and Santamélia), two experiments, completely randomized and arranged in subdivided plots with five replicates, were conducted under the environmental conditions of Boa Vista, Roraima, Brazil. Treatments consisted of the association among five environments (A1 - greenhouse, A2 - Chromatinet ® 35% red, A3 - Chromatinet ® 50% red, A4 - Chromatinet ® 35% Silver and A5 - Chromatinet ® 50% Silver) and four substrates S1 - OrganoAmazon®; S2 -OrganoAmazon® + PuroHumus®; S3 - OrganoAmazon® +... |
