Sixty fungal samples were divided into different groups according to colony morphology and ITS (internal transcribed spacer) sequences. Google Scholar, Alves A, Crous PW, Correia A, Phillips AJL (2008) Morphological and molecular data reveal cryptic speciation in Lasiodiplodia theobromae. Common diseases of Chinese hackberry are powdery mildew, stem and root rot, twig blight and leaf spot. Host trees normally decline for a variable period of time and then die. 1c). At the same time, it has a wide range of hosts. I would expect to see these diseases on stressed trees, so look for root or trunk injury, evidence of a grade change or construction nearby, or some change since symptoms appeared. 2014; Trakunyingcharoen et al. 2016), Albizia falcataria (L.), Paulownia spp., Mangifera sylvatica, Eucalyptus spp. 31, 2571–2580 (2020). Therefore, control measures should be carried out in the early stage of discovery of the disease. Hackberry trees are often planted as street or lawn trees and can even be planted near buildings or sidewalks. Bootstrap support values from 1000 bootstrap replications are showed. d Liquid secretions may mark the open position of the conidia, Conidial morphological characteristics for L. pseudotheobromae isolate Ls7 seen under the light microscope. The online version is available at http://www.springerlink.com. Why the hackberry is not a more well known tree is a complete mystery to me. These sequences were aligned using MEGA version 5.0. J. The fungus was recovered from the symptomatic inoculated tissues and the culture’s characteristics and morphology were similar to the Ls7 isolate. 2010; Sakalidis et al. The results show that isolates of Lasiodiplodia sp. It has a slender trunk that grows to a height of sixty feet in the middle states, but can be much taller the further south it grows. The pycnidia or fruiting body of the fungus is produced near the canker before spreading to neighboring hosts. 6). Transverse sections of xylem tissue were also black–brown (Fig. Growth & leaves size, shape, appearance similar to American elm. Step 3 was repeated and 30 µL of ddH2O was added to obtain a solution of the DNA. The pathogen overwinters in the soil, and in the summer of the following year, conidia and conidiomata are spread by wind and rain (Yee et al. Ganoderma root and butt rot Ganoderma spp. In the summer of 2017 in Shuyang, Jiangsu Province, a severe outbreak of Chinese hackberry disease appeared. Australas Plant Dis Notes 10(1):21, Dou ZP, He W, Zhang Y (2017) Lasiodiplodia chinensis, a new holomorphic species from China. In other seasons the disease is less aggressive (Wu et al. Conidia were oval, both ends round and blunt, wider in the middle, initially transparent and aseptate or not partitioned (Fig. In severe cases, they may even lead to plant death (Alves et al.

If left untreated it will cause rapid decline and death. 2007; Correia et al. Although they are closely related, the size and shape of L. pseudotheobromae conidia differ from those of L. theobromae which are larger and have orbicular ends (Alves et al 2008). In China, it is mainly distributed in central and eastern portions of the country, including Beijing, Jiangsu, Hubei, Sichuan, and Shandong (Li and Li 2015). The fungal samples categorized as Ls7 type in this study showed similar features with L. pseudotheobromae and was consistent with these characteristics.

However, with increased planting, Chinese hackberry diseases are increasing and becoming more and more serious (Cacciola 2000; Berbegal et al. 2008; Abdollahzadeh et al. Jake at TREES BY JAKE is an ISA Certified Arborist and has extensive experience in identifying and diagnosing all types of tree disease, including root rot. Based on the phylogenetic relationship of β-tubulin, Cheng (2012) concluded that the sexual stage of L. pseudotheobromae may be Botryosphaeria rhodina. 2017). 4d, e). The lesions were approximately 98 mm × 6 mm (Fig. Additional comments: Western hackberry is an exceedingly tough tree with a homely and clumsy appearance; ergo, it is rarely planted as an amenity tree in Phoenix landscapes. To root your BlackBerry KEY2 with Kingo Root, it is incredibly basic. Heavy soils and/or caliche cause poor soil drainage. The occurrence of the disease should be closely monitored and preventative measures put in place to avoid the spread of the disease. Colony characteristics for L. pseudotheobromae isolate Ls7. M.Sc. In addition, it also can infect Acacia confusa Merr (Dou et al. c Canker spots extended longitudinally in the later stages of the canker disease. 1b). It is a moderately long-lived hardwood with a light-colored wood, yellowish gray to light brown with yellow streaks.. This site was last updated on November 30, 2020.

Common hackberry is a large deciduous tree reaching 12 m to 18 m in height at maturity. The twigs and stems of all infected seedlings became cankerous and turned black, which was devastating to Chinese hackberry plantations. Root Rot Diseases: Root rot diseases are caused by fungi that are found in the soil and attack the roots of plants. (2008). Common hackberry is more susceptible to an unsightly witches-broom, which can disfigure branches but does not seriously affect the health of the tree.

However, the sexual morph of the Ls7 isolate was not found in this study. Two seedlings inoculated with Ls7 isolate developed canker spots on days 23 and 27 after inoculation, respectively. If you have problems with hackberry leaf drop, give us a call. There were many short conidiophores on the inner walls and conidia on the conidiophores. 2015). The isolate from xylem tissue with a high frequency (> 50%) was named Ls7 type. Eventually, the twigs wilted. It differs from sugar hackberry in that the leaves are toothed and not smooth. Following 2 weeks of treatment under UV light, the colonies produced pycnidia (Fig. d Mature conidiomata on the disease site in this disease. i A condium with partial germ tube (Bars = 10 µm), Fungus isolate Ls7 a unique dark pink colony under incubation at 35 °C. 2b). 2011; Ismail et al.

Kingo SuperBattery is for rooted Android that Closes background apps and services to optimize your phone. The symptoms of canker began to develop 20 days after inoculation with Ls7 isolate and by day 35, there were dark, enlarged longitudinal lesions. a Colony on white background. This tree is also well suited to urban conditions and can be used in yards and patios as well as along street and boulevards. nov. on Quercus species, with notes and description of Botryosphaeria stevensii and its anamorph, Diplodia mutila. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. The procedure was: (1) mycelium grown for 3–4 days was placed in 2 mL test tubes with 500 µL of 2 × CTAB (containing 1% β-mercaptoethanol), rapidly cooled for 30 s in liquid nitrogen, and then heated immediately to 65 °C for 30 s. This was repeated three times; (2) a 1/2 volume of glass beads was added to each test tube before placing on a vortex shaker for 4–5 min, followed by heating to 65 °C for 20 min and shaking once every 10 min. Conidia exist all year-round but are rarely detected in winter (Xu et al. Armillaria root rot is a likely fungal disease of hackberry, and … The experiment was carried out during the summer of 2018. Fungal conks, a semicircle shelf fungi, can be found from the base of the tree up to 3 feet high on the trunk; Conks are reddish brown and shiny on top, white and porous underneath; a rim of white may be visible on the edge of growing conks; Infected wood at the tree base is white, soft, stringy or spongy Fungal Divers 41:53–69, Phillips AJL, Alves A, Pennycook SR, Johnston PR, Ramaley A, Akulov A, Crous PW (2008) Resolving the phylogenetic and taxonomic status of dark-spored teleomorph genera in the Botryosphaeriaceae.
