“…An ammonia-based chemical reagent has been developed to be effective against P. noxius , but it has side effects on soil characteristics and root growth [7]. Recently, the chemical fumigant dazomet has been reported to be a possible means of preventing P. noxius incursion in agriculture [8]. In fact, there is no effective way to completely eliminate this fungus in soil by the existing chemical strategies.…”

Abstract:In this study, the effect of phenazine-1-carboxylic acid (PCA) on morphological, physiological, and molecular characteristics of Phellinus noxius has been investigated, and the potential antifungal mechanism of PCA against P. noxius was also explored. The results revealed that PCA showed in vitro antifungal potential against P. noxius and completely inhibited P. noxius hyphae at concentrations >40 µg/mL. PCA inhibited both mycelial growth and the loss of mycelial biomass in vitro in a dose-dependent manner. Morphological changes in PCA-treated P. noxius hyphae, such as irregularly swollen mycelia as well as short hyphae with increased septation and less branching, were observed by optical microscopy. The intracellular reactive oxygen species (ROS) levels were significantly increased in PCA-treated P. noxius cells as compared to control groups. Induced hyperpolarization of the mitochondrial membrane potential (MMP), repressed superoxide dismutase (SOD) activity and up-regulated gene expression of seven tested genes were also found in PCA-treated P. noxius groups. Thus, the present results suggested that the mechanism of action of PCA against P. noxius might be attributed to direct damage of mycelium and high intracellular ROS production, and indirect induction of genes involved in cell detoxification, oxidation-reduction process, and electron transport of the respiratory chain.

ARP (Apple replant problem, ARP) , which is also known as the continuous cropping obstacles of apple, influences the cultivation of replanted fruit trees. It occurs in all major apple planting regions throughout the world. Generally, it is believed that both biotic and abiotic factors act together to cause ARP, and that the biotic factors are recognized as the main cause of continuous cropping obstacles. This study aims to examine the responses of Malus hupehensis Rehd. and edaphon to dazomet, which was used to alleviate ARP, and to develop an effective method to prevent and cure ARP. The study was carried out in 2012 at the

The Induction of Adventitious Roots Regeneration before Transplanting Rootless Ficus elastica Heritage Tree

Heritage trees carry both botanical and historical value for a city’s resilience and sustainability and hence are precious and unique. Their transplant is costly and very rare due to tremendous cost and 100% survival requirement by law. Rootless transplant is even more detrimental to the heritage tree due to removal of roots infected by brown root rot (BRR) before transplanting. This study examined the adventitious roots (AR) induction ability of the Ficus elastica Roxb. heritage tree infected with BRR. The experimental design considered three factors: root diameter (RD), wounding method (WM), and auxin solution on aerial roots under fractional factorial experiment in completely randomized design (CRD). There were four RD groups: RDI (RD < 2 cm), RDII (2 ≤ RD ≤ 4.3 cm), RDIII (4.3 < RD ≤ 22), and RDIV (RD > 22); three WMs: cutting off (CF), girdling (GD), and rectangular shape peeling (RP) of aerial roots; and three auxin solutions: 2000 mg·L−1 IBA(Indole-3-butyric acid) (2B), 2000 mg·L−1 IBA + 2000 mg·L−1 NAA(1-Naphthaleneacetic acid) (2NB), and 4000 mg·L−1 IBA (4B) plus water as control (C). The number of rooting wounds, number of roots, and the mean length of the three longest adventitious roots in each wound were recorded to evaluate the AR rooting performance. Twenty four treatment combinations including 328 wounds were tested. The results showed that rooting ability was significantly correlated with RD and WM. Smaller RDs had better rooting and declined with increased RDs. CF had the best rooting followed by GD and then RP. Auxin solution did not significantly affect the rooting ability. It may be due to the abundant endogenous auxin in the heritage tree, which mitigated the effect of exogenous auxin for AR induction. We conclude that cutting off small-diameter aerial roots is the best approach to induce ARs from rootless F. elastica heritage trees to enhance transplantation success.
