3 weeks 3 hours ago

Dr. Jie Gao, a recent Ph. D. graduate, is an associate professor at the Environmental Horticulture Research Institute, Guangdong Academy of Agricultural Sciences, China. The objective of her study focused on the molecular regulation mechanisms of Chinese orchid, Cymbidium sinense, leaf variegation. The Chinese orchid is a symbol of elegance and purity in China. Among Chinese orchids, the leaf color variation of C. sinense is the most abundant. The leaf color variation makes C. sinense more diversified and more valuable. However, the variegation formation process remains largely unexplored.

Mimicking the fruit repression effect on Citrus flowering through continuous gibberellic acid treatments
3 weeks 3 hours ago

In Citrus, flower intensity could be partially reduced or increased by applying gibberellins (GA3) or paclobutrazol (PBZ). However, under extreme harvest conditions, very high or very low treatments of these chemicals do not have any effect. Fruit inhibits flowering by activating CcMADS-box19 gene expression in the leaf, which blocks the inductive signalling preventing the expression of the CiFT3 gene. But signals that activate this repressive mechanism are unknown. The hypothesis of hormonal signalling is based on the inhibitory effect of GA3 on flowering.

Modifications of the texture of tomato purees by variety selection or by processing methods result from various physico-chemical parameters
3 weeks 3 hours ago

Tomato is the main horticultural crop for processing industry. Tomato puree is a source of phytonutrients such as carotenoids. Puree viscosity is a major quality trait, and industrial companies need reliable indicators of tomato fruit ability to produce viscous puree. Fruit quality is primarily assessed by measuring the soluble solid content, which is insufficient to predict puree viscosity. The choice of the variety and transformation process are the levers for action used by industrial producers to manage the final puree viscosity.

However, the underlying mechanism is unknown.

Stimulation of adventitious root formation by laser in rose cuttings
3 weeks 3 hours ago

Wounding is a fundamental factor effecting the survival of woody cuttings for plant propagation. Adventitious rooting is directly related to mechanical damage as a result of plant detachment. In this sense, methods of manipulating wounded regions to stimulate adventitious roots have most frequently been applied to hardwood species. Our first experiments investigating the role of wounds in cutting propagation of woody species indicated that additionally injured tissue along the cutting base showed an apparent increase in rooting compared to uninjured controls.

Conservation of dragon fruit genetic resources using seeds as well as clonal material
3 weeks 3 hours ago

To face the future, farmers and breeders need access to a large genetic diversity. This diversity helps them to adapt to new circumstances, such as droughts by developing and planting drought tolerant varieties. This diversity has to be stored somewhere and while in situ conservation is essential, it is in general more difficult to access and if unprotected at risk of disappearing. Gene banks therefore play an important role, providing ex situ conservation approaches such as field or seed banks. However, these gene banks face their own challenges.

Distribution and major morphological traits of wild asparagus (A. acutifolius L. and A. albus L.) in Sicily
3 weeks 3 hours ago

Asparagus officinalis L. (family: Asparagaceae) is the only cultivated member of the genus though many other congeners are widespread within global flora. Among these, A. acutifolius L. and A. albus L. are widely represented in the Mediterranean basin. Since ancient times, they have been used by local populations for food and medicinal purposes. The present focus on these wild plants originates from their rediscovered use in local cuisine, the related biodiversity protection systems, and their consequent agronomic potential as new crops.

Effect of growth unit characteristics and light environment on leaf fall in the evergreen mango tree
3 months 1 week ago

Leaf fall in the evergreen mango (Mangifera indica L.) is affected by physiological age and light environment. Details of these effects need to be determined. Previous studies have not described the dynamics of annual leaf fall of these trees. Our work aimed to decipher the effects of architectural and environmental factors on leaf fall at the scale of the growth unit (GU) during a year. Our experiment began by describing the initial states of 240 GUs, sampled from five mature ‘Cogshall’ mango trees at three depths, expressed as 1, 2, or 4 GU from the terminal GU along the branch.

Apple trees in garden-orchard system improve soil quality and yield of organic radish preceded by lettuce
3 months 1 week ago

Maintaining healthy soil is a major challenge in agriculture. Tree-based intercropping is very promising to ensure high production and conserve soil quality, as shown in agroforestry systems. Trees improve soil fertility through the input of organic matter by litterfall and root turnover, which enhance the soil microbial activity. This study aims to evaluate the effects of apple trees (Malus × domestica Borkh. ‘Golden Delicious’) on soil qualities and their potential to improve the yield of an unfertilized organic radish crop (Raphanus sativus L. ‘Ostergruss’).

Transcriptomic and physiological responses of Diplotaxis tenuifolia under heat stress
3 months 1 week ago

To determine strategies to increase plant tolerance to high temperature we must examine plant physiological and metabolic processes. High temperature leads to an alteration in photosynthesis, modification of plant metabolism, plant growth reduction, and overall reduction in the quality of horticultural products. Diplotaxis tenuifolia L., commonly known as wild rocket, is a member of the mustard family, Brassicaceae. This plant is cultivated as a baby-leaf salad. Our goal in this study was to understand the physiological and molecular responses in this plant when subjected to heat stress.
