In Vitro Plant Regeneration of 'Madame Vinous' Cultivar of Sweet Orange (Citrus Sinensis L. Osbeck) / Subedi, G.D. ; Paudyal, K.P.
Title : In Vitro Plant Regeneration of 'Madame Vinous' Cultivar of Sweet Orange (Citrus Sinensis L. Osbeck) Material Type: printed text Authors: Subedi, G.D., Author ; Paudyal, K.P., Author Pagination: 41-44 p. Languages : English (eng) Keywords: citrus, hormones, in-visro. root and shoot regeneration Abstract: wboratory experiments were conducted at National Citrus Research Program, Dhankuta in
two consecutive years (200212003 to 200312004) to optimize tl1e protocol for in vitro plalll
regeneration'of Madame Vinous Cultivar of Sweet Orange (MVSO). Five different levels of
BAP and two levels of fAA were tested in a factorial Randomized Complete Block Design
(RCBD) with six replications. The best treatment, in terms of response frequency and mean
number of axillary shoots per explant was 011 MS medium ( f962) supplemented with 0.5 mg/1
BAP and 0.2 mg/1/AA (4.8 shoots per explant). Effective rooting was observed on MS medium
supplemented with 0.5 mg/1 fAA. The in vitro rooted plantlets were acclimatized in Cello
polyethylene containers for four weeks in room temperature followed by transferring them
i11to the glasshouse. The results reveled that a11 efficient system for in vitro plant regeneration
by multiple shoot formation from in vitro shoot tip explams of MVSO has been successfully
established, thus it is useful for the production of disease free plallling materials. The
pathogen free plants of MVSO could be used as indicator plallf for Biological Indexing of
Citrus Greening Disease caused by gram-negative bacterium (Liberibacter asiatic:um).Link for e-copy: http://elibrary.narc.gov.np/?r=451 In Vitro Plant Regeneration of 'Madame Vinous' Cultivar of Sweet Orange (Citrus Sinensis L.

Title : A review on management of fruit drop in mango and citrus Material Type: printed text Authors: Gautam, I.P., Author Pagination: 28-32 p. Languages : English (eng) Keywords: Citrus, fruit drop, management, mango Abstract: Mongo and Citrus are important fruits in Nepal. They occupied about 9% and 25% of total fruit cultivated areas respectively in Nepal. However, the notional productivity of mango (7.0 t/ha) and citrus (10.38 t/ha) is very low. Besides other factors, fruit drop is a serious cause of low productivity in both fruit crops. In nature, fruit drop of mango and citrus hove been found very high accounting 99% and 93.52-96.63% respectively. Considering these facts, a number of studies in fruit drop, fruit development stages and their control measures have been reviewed to attract the attention of large number of workers and extension agents for minimizing the fruit drop problem in mango and citrus. The results of the investigations showed that fruit drop is a complex problem involving several factors. Application of recommended dose of fertilizers with spraying 2% urea or 4% calcium nitrate containing 50 mg boric acid/lit water reduced fruit drop. Among the various growth regulators, application of NAA and 2,4-D (10-20 ppm) in mango during April to May found effective for retention of fruits in North India condition. Similarly, in citrus 2,4-D ( 10-20 ppm), 2,4,5-T and GA were found effective for controlling fruit drop. The application IAA and NAA were found ineffective due to increase the abscission zone of the fruit.

Title : Growth of Trifoliate Orange (Poncirus Trifoliata L.) Seedlings at Different Management Condition in Ncrp, Dhankuta. Material Type: printed text Authors: Shrestha, R.L., Author ; Paudyal, K.P., Author ; B. Chalise, Author ; ,Subedi, H.P., Author ; J. L. Mandal, Author Pagination: 35-41 p. Languages : English (eng) Keywords: Trifoliate orange, Citrus, nursery, media, polypot, seedling, rootstock, vermicompost,
polyhouse.Abstract: Citrus fruits are grafted in trifoliate orange {Poncirus trifoliate L) due to good fruit quality,
dwarfness, tolerant to soil born disease, cold and hardiness. Slow growth rate of trifoliate orange is
one of the serious problems of citrus nursery owners. It takes more than three year to attain the
grafting requirement for sapling production. Facing this problem an experiment was conducted on
trifoliate orange to accelerate the growth rate of seedlings. Seedlings are grown in different media
under three different environment condition i.e. polyhouse, plastic tunnel and open field condition
in NCRP, Dhankuta in Fiscal Year 2063/64 and 064/65. Seeds were grown in five different media
(five treatments) and replicated four times. Highest seedling height (83.67 em) and diameter (7.14
mm) was observed in polyhouse condition with vermin compost+ soil mixed {I: I) treatment where
as lowest height (28.20 em) and diameter (3.58 mm) observed in open field condition in the same
treatment within one year. The result shows that, highly significant effect of environmental
condition on seedling growth. Seedlings height of trifoliate orange is almost three times and
diameter was two times greater in polyhouse as compared to open field. Therefore, result of this
experiment guided to the nurseryman's, to grow the trifoliate orange seedling in the polyhouse
condition with soil and vermicompost mixed media (I: I) to accelerate growth of the seedlings and
to get stander height and diameter within one-year period This technology will be applicable to the
nursery mans to improve the quality of saplings in the nursery.Link for e-copy: http://elibrary.narc.gov.np/?r=1629 Growth of Trifoliate Orange (Poncirus Trifoliata L.)
