Abstract
Melon grafting represent an increasingly important strategy against biotic and abiotic stresses. Cucurbita hybrid rootstocks have been extensively developed for this purpose, but it is necessary to find new alternatives. In this work, several experimental rootstocks of cultivated and wild resources from the Cucurbita and Cucumis genera have been evaluated using Piel de Sapo melon as scion. Cucurbita rootstocks tended to increase fruit size and seed cavity and offered more rounded shapes at the early stages of ripening, but this effect was later minimised. Cucumis rootstocks tended to show less vigour than those of Cucurbita. C. metuliferus hybrid rootstock caused plant collapse at specific environmental conditions, probably due to differences in the growth of rootstock and scion. One of the Cucurbita maxima x C. moschata and the Cucurbita pepo experimental hybrids were also less vigorous, delaying flowering and fruit set, and compromising yield. The effects of Cucurbita and Cucumis rootstocks on sugar and acid accumulation of Piel de Sapo were almost negligible, but they altered the volatile profile. This last impact depended on the specific scion x rootstock interaction and the environmental conditions. Cucumis rootstocks tended to minimise it, especially the hybrid Cucumis melo subsp. melo x C. melo subsp. agrestis Pat 81, which offered a volatile profile highly resembling the non-grafted control. Among Cucurbita alternatives, the commercial hybrid Cucurbita maxima x C moschata had the lowest impact, while other experimental hybrids C. moschata x C. moschata and C. maxima x C. moschata increased levels of alcohols. Among Cucumis rootstocks, the hybrids of wild species Cucumis ficifolius x C. anguria and C. ficifolius x C. myriocarpus, and C. metuliferus had a higher impact on the volatile profile.
甜瓜嫁接是一种日益重要的应对生物和非生物胁迫的策略。为此,葫芦杂交砧木已得到广泛开发,但仍有必要寻找新的替代品。在这项工作中,使用 Piel de Sapo 甜瓜作为接穗,对葫芦属和葫芦科的几种栽培和野生资源的实验砧木进行了评估。葫芦科砧木在成熟初期往往会增大果实尺寸和种子空腔,并提供更圆润的果形,但这种影响随后会减至最小。葫芦科砧木的活力往往不如葫芦科砧木。C. metuliferus 杂交砧木在特定环境条件下会导致植株倒伏,这可能是由于砧木和接穗的生长差异造成的。其中一个 Cucurbita maxima x C. moschata 和 Cucurbita pepo 试验杂交种的活力也较弱,推迟了开花和坐果,影响了产量。葫芦和葫芦砧木对沙坡头糖和酸积累的影响几乎可以忽略不计,但它们改变了挥发性物质的分布。最后一种影响取决于具体的接穗和砧木相互作用以及环境条件。葫芦科砧木的影响往往最小,尤其是瓜亚种 Cucumis melo x C. melo subsp.在葫芦替代品中,商品杂交种 Cucurbita maxima x C moschata 的影响最小,而其他实验杂交种 C. moschata x C. moschata 和 C. maxima x C. moschata 则增加了醇的含量。在葫芦科植物的砧木中,野生种 Cucumis ficifolius x C. anguria 和 C. ficifolius x C. myriocarpus 的杂交种以及 C. metuliferus 对挥发性物质的影响较大。
期刊介绍:
The European Journal of Agronomy, the official journal of the European Society for Agronomy, publishes original research papers reporting experimental and theoretical contributions to field-based agronomy and crop science. The journal will consider research at the field level for agricultural, horticultural and tree crops, that uses comprehensive and explanatory approaches. The EJA covers the following topics:
crop physiology
crop production and management including irrigation, fertilization and soil management
agroclimatology and modelling
plant-soil relationships
crop quality and post-harvest physiology
farming and cropping systems
agroecosystems and the environment
crop-weed interactions and management
organic farming
horticultural crops
papers from the European Society for Agronomy bi-annual meetings
In determining the suitability of submitted articles for publication, particular scrutiny is placed on the degree of novelty and significance of the research and the extent to which it adds to existing knowledge in agronomy.
