Population Dynamics of Mistletoes: Case Study on Golden Shower (Cassia fistula L.) in Purwodadi Botanic Garden, Indonesia | Chapter 2 | Contemporary Research and Perspectives in Biological Science Vol. 6

Background: There were about 1600 species of mistletoes throughout the world except Antarctica. Loranthaceae is the most dominant family and has the most species of mistletoe in tropical zones.

Aims: The aim of the study is to document the population distribution and dynamic of mistletoe species within this study site and to uncover their diversity in C. fistula in Purwodadi Botanic Garden, Indonesia.

Place and Duration of Study: Research was conducted in Purwodadi Botanic Garden during 2012- 2019.

Methodology: An explorative and descriptive study design was adopted. Data of mistletoes species and hosts, number of parasites, plant height, and stem diameter at 120 cm of DBH was collected by direct observation in determined blocks, where the mistletoes and C. fistula were found. Binocular was used to observe and count the mistletoes on the hosts. Infested host prevalence was counted by the proportion of the number of the infested host by mistletoes and the total number of hosts, while parasite density shows the proportion of parasite number (individual) and the total number of hosts.

Results: The population of mistletoe Dendrophthoe pentandra and Viscum articulatum in Cassia fistula varied by year and environment of habitat. The density of D. pentandra and V. articulatum has increased since 2012 and reached the highest density in 2015. The density of D. pentandra in the blocks differs significantly. V. articulatum is a hyperparasite mistletoe only found as a parasite on D. pentandara in C. fistula.

Conclusion: There were two mistletoes parasitized Cassia fistula in Purwodadi Botanic Garden during 2012-2019, i.e. Dendrophthoe pentandra and Viscum articulatum. The infestation and density of mistletoes on their hosts are dynamic in a community. The parasite density tend to increase from 2012 until 2015 and then decline to the lowest in 2019. The highest declining population due to mortality of mistletoes occurred in 2019 after 2015.

Exploring the Diversity and Infestation of Mistletoes in Cultivation of Sengon (Falcataria falcata (L.) Greuter & R.Rankin) in Malang East Java Indonesia | Chapter 5 | Geography, Earth Science and Environment: Research Highlights Vol. 3

Aims: To invent the diversity and infestation of mistletoes and their hosts in several planting patterns of sengon (Falcataria falcata (Miq.) (L.) Greuter & R. Rankin).

Study Design: Explorative and descriptive.

Place and Duration of Study: Malang Regency, East Java, Indonesia at an altitude of about 100 - 900 m asl from September until December 2021.

Methodology: Data on mistletoes and their hosts was collected by exploratory and descriptive methods in ten districts and twenty villages. Purposive sampling was used and determined along tracks in line transects where sengon cultivation was found. Sample plots of 10x10 m were determined and made in each planting pattern to enumerate the number of mistletoes, hosts, and infested hosts. They are used to determine the severity infestation of mistletoes on the hosts.

Results: There were two species of mistletoe discovered in sixteen planting patterns of sengon, i.e., Scurrula atropurpurea (Blume) Danser and Viscum ovalifolium L. S. atropurpurea was the most dominant mistletoe with parasite number of 906 individuals. The highest number of trees, infested trees, and mistletoes were obtained in the monoculture pattern of sengon. The severity index of mistletoes infestation varied between the planting patterns. The average value of the severity index in all cultivation patterns of sengon was categorized as low.

Conclusion: Scurrula atropurpurea (Blume) Danser and Viscum ovalifolium L. are the two species of mistletoe discovered in the cultivation of sengon in Malang Regency. The most dominant mistletoe was S. atropurpurea with a parasite number of 906 individuals. The highest number of trees, infested trees, and mistletoes were obtained in the monoculture pattern of sengon. The heaviest severity index of mistletoes infestation was found in tangerine citrus + sengon i.e., 15. The average value of the severity index in all cultivation patterns of sengon was categorized as low, i.e., 5.28.

Studies of Mistletoe Presence on Five Tree Species of Samaru Area, Nigeria | Chapter 7 | Recent Progress in Plant and Soil Research Vol. 1

 Mistletoe infestations on trees require immediate attention because they reduce the vigor of tree growth and reproduction. There are few or no records on the type of mistletoe species found parasitic on tree species in Samaru. The study aimed to determine the different species of mistletoe parasitic on Albizzia lebbeck, Citrus grandis, Khaya senegalensis, Terminalia mantaly, and Terminalia catappa within Samaru, Nigeria, in order to document and know the species richness of mistletoe within this region. Based on the presence of the studied species and mistletoe infection of the trees, the study site was divided into four sampling areas. The study found that A. lebbeck was infected by six different species of mistletoe from all sampling areas: Tapinanthus dodoneifolius, Tapinanthus globiferus, Globimetula braunii, Globimetula oreophila, Englerina lecardii, and Tapinanthus belvisii; C. grandis, T. catappa, and T. mantaly each had four different species found parasit A. lebbeck had the most mistletoe species found parasitic on it, while K. senegalensis had the fewest. The most common were G. braunii and T. globiferus. In the study area, common mistletoe species were found parasitic on all of the targeted host trees, whereas T. dodoneifolius was found parasitic only on A. lebbeck and T. catappa, and E. lecardii was found parasitic only on A. lebbeck and C. grandis. In conclusion, A. lebbeck was the most vulnerable to mistletoe attack in the study area, while G. braunii and T. globiferus were less host specific.
