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.

Leaf Extract of Cassia fistula: A Biofungicide against Colletotrichum gloeosporioides and Cercospora bataticola| Chapter 8 | Cutting Edge Research in Biology Vol. 1

 Indiscriminate and unrestrained use of chemical fungicides have grown resistant in many fungal plant pathogens that challenging to control most fungal plant ailments. Since the dawn of time, phytochemicals have donated a important role to human prosperity without producing any harm. PFT means with various leaf extracts of Cassia fistula (Aqueous, methanol and acetone)  and their three concentrations (250µl, 500µl and 1000µl per 15 ml of PDA) were secondhand against Colletotrichum gloeosporioides causing anthracnose (a post-harvest ailment of fruits) and Cercospora bataticola, leading to leaf spot of vegetable. The study's findings disclosed that maximum inhibition (76.8%) of Colletotrichum gloeosporioides was establish with1000µl concentration of methanolic extract of Cassia fistula leaves 3 DAI while maximum restriction of Cercospora bataticola (68.7%) was found accompanying the same aggregation of acetone extract of Cassia fistula leaves 3 DAI. Considerable growth restriction of Colletotrichum gloeosporioides (68.7%) and Cercospora bataticola (50.5%) were found accompanying 1000µl aggregation of methanolic and acetonic extracts of Cassia fistula leaves. 5 DAI. Acetonic extract of Cassia fistula leaves with 1000µl aggregation was also erect as a good antifungal for Colletotrichum gloeosporioides with 64.8% and 54.6% progress inhibition 3 DAI and 5 DAI individually. The current study found that methanolic and acetonic leaf extracts of Cassia fistula maybe used for fungal plant ailment management, but more research is wanted.

Determining the Effect of Cassia fistula (L) Flower Extract on Antioxidant Defense in Streptozotocin Induced Diabetic Rats| Chapter 7 | Challenges and Advances in Pharmaceutical Research Vol. 8

 Diabetes mellitus is a metabolic complaint with multiple etiologies characterised by habitual hyperglycemia and disturbances in carbohydrate, fat, and protein metabolism caused by blights in insulin stashing, insulin action, or both. There was a significant increase in blood glucose, glycosylated hemoglobin and attendant drop in tube insulin in STZ convinced rats were regressed back to near normal in diabetic rats treated with cassia fistula and glibenclamide treated rats. The current study demonstrates that STZ- convinced diabetic creatures have increased oxidative stress. In experimental rats, the ethanolic excerpt of cassia fistula flowers exhibits significant antihyperglycemic as well as antioxidant exertion. Our result is harmonious with the results of who reported a drop in antioxidant enzymes similar as SOD, CAT and glutathione peroxidase in diabetes mellitus. The presence of phytochemicals enhances cassia fistula flowers' capability to cover the towel defence system against oxidative damage in STZ- convinced diabetes. Our results indicate that the preventative goods of cassia fistula flowers may be due to inhibition of lipid peroxidation and scavenging of free revolutionaries by its antioxidant nature.
