Residual Effect of Partial Girdling on Quality of Satsuma Mandarin Fruit / A. K. Shrestha in Nepalese Horticulture, v. 10: 1 ([07/25/2015])
[article]
Title : Residual Effect of Partial Girdling on Quality of Satsuma Mandarin Fruit Material Type: printed text Authors: A. K. Shrestha, Author ; W. Kibet, Author Publication Date: 2015 Article on page: 71-75 p. Languages : English (eng) Keywords: Acidity, Brix, Girdling, Satsuma mandarin Abstract: An experiment was carried out to evaluate the residual effect of partial girdling on fruit
quality and bark recovery of Satsuma mandarin three years after the date of girdling
operation. In 2003, fruit trees located in the University Farm of Ehime University
received the girdling treatment of 10 cm and 20 cm width to compare the effect with
ungirdled (control) branch. After three years, the bark recovery was found to be
significantly higher in the branches that received girdling of 10 cm width than 20 cm
girdling treatment. The fruit size, total soluble solid content and the titratable acidity
were not significantly different among the three treatments. However, the largest fruits
(98.4±3.52 g) were obtained from the ungirdled branch while the highest brix (10.5 ±
0.25 %) was recorded in the fruits harvested from the 10 cm girdled branches.

Title : Life Cycle and Behavior of Citrus Green Stink Bug, Rhynchocoris Lmmeralis Thunberg Material Type: printed text Authors: Manandhar, R., Author ; Joshi, S.L., Author ; Sharma, P. N., Author Pagination: 50-54 p. Languages : English (eng) Keywords: citrus green stink bug, fruit drop, life cycle, mandarin orange Abstract: Rhynchocoris Jwmeralis Thunberg (Citrus green stink bug: CGSB) is one of the important
insect pests of mandarin in the westem hills of Nepal, that causes premature fruit drop in
mandarin, resulting heavy loss in fruit yield. This study aims to manage it through integrated
approach, which comprises of its field life cycle and behavior. This study was carried at
Hemja (1060 mas 1.) and Lrmrfe (1675 mas l.) during June to December 2001 and 2002.
Freshly hatched nymphs were inoculated in sleeve cage that was confined to a branch having
2-3 small fruits. Observations were made to record incubation period of egg, duration of each
nymphal instar and number of dropped fruits at each instar. This study revealed that the pest
had five nymphal stages prior to emerge as an adult. The first instar stmted feeding on the
fruit that induced fruit drop. The adult of CGSB remained alive for more than 50 days in the
winter to build population for the next season.Link for e-copy: http://elibrary.narc.gov.np/?r=454 Life Cycle and Behavior of Citrus Green Stink Bug, Rhynchocoris Lmmeralis Thunberg [printed text] / Manandhar, R., Author ; Joshi, S.L., Author ; Sharma, P. N., Author . - [s.d.] . - 50-54 p.
