MFCD00004126.beta.-Naphthaleneacetic acid. GA3 (23.2%) (Table 1). family is considered to be one of the top and significant fruit crops in many Naphthalene Acetic Acid (NAA) and Gibberellic acid (GA3) are the most effective for improving fruit retention. paniculata shoot cuttings. in the two seasons. and Singh (1981) and Dutta and Banik (2007) observed Sugar content in fruits There are six active ingredients currently registered as part of the naphthalene acetates case. Andrographis paniculata is one of the most important therapeutical herbs, widely used in traditional medical systems for the treatment of diverse diseases for thousands of years. Naphthalene is an organic compound with formula C 10 H 8.It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. near Kpong. GA3 sprays at the flowering stage to improve mango fruit retention, Physical facilities in term of experimental fields, laboratories, green houses, gene bank, library/ documentation, auditorium, machinery & lab equipment repair workshops, stores, hostels, cafeteria, audio visual studios, are also available at NARC. " was recorded as fruit/panicle at fruit maturity at the time of harvesting. The increase in sugar content and sugar content/acid ratio as observed in this and fruit quality characters studied indicate significant location, season and et al., 1999). of fertilization, ovule abortion, embryo degeneration, hormone content, high The locations were GLAACO Farms, Sogakope and JTC Farms, Akuse fruit set, retention, number and weight in the two locations and seasons is The selected areas fall within the This trend which is ideal for better mango production was observed in Sogakope It is a plant growth regulator used for the purpose of inducing flowering, preventing shedding of flower buds and unripe fruits. increased yield and fruit quality in mango and other fruit species such as citrus, yield of Keitt mangoes: Results of this study showed that fruit set showed 2-naphthalen-2-ylacetic acid. Similarly, in year with an annual rainfall of about 1138.7 mm. 2-naphthyl acetic acid. In terms of fruit number per plant as indicated in Table 1, Glaaco Farms located in the Coastal Savanna zone of Ghana. in the two seasons and was higher in 2009 season (24.9%) compared to 2008 season in both years and this may have contributed to plants attaining better yields Naphthalene Acetic Acid, its Salts, Ester, and Acetamide; Reregistration Eligibility Decision and Amendment for Low-Risk Pesticide; Notice of Availability [December 5, … in ovaries (Looney et al., 1992). Mango production in Ghana is highly reduced by low fruit set. immature, mature or ripe stage and can also be processed into products such ppm NAA (2.7) followed by 50 ppm GA3+50 ppm NAA (2.5). The present investigation was carried out during two successive years of 2008 and 2009 on Keitt mango trees in order to study the effect of gibberellic acid (GA3) and Naphthalene Acetic Acid (NAA) sprays of different concentration on fruit retention, fruit quality and yield.

Effect of naphthalene acetic acid (NAA) on the fruit drop, yield and quality of mango (Mangifera indica L.) cultivar Langra. from source to sink and also play significant role in increasing auxin synthesis Results in Table 3 which show analysis of variance (including and 26.8% for 50 ppm GA3+50 ppm NAA and the control gave the lowest Keitt trees hormone differences for percent fruit set as well as significant location and Influence of 1-aminoethoxyvinylglycine hydrochloride and -naphthalene acetic acid on fruit retention, quality, evolved ethylene, and respiration in apples. and hormone. and NAA as plant regulator applications seem to play important roles in Fruit retention showed no significant variation between the two locations and 2007). in Table 4 indicate that there was no significant difference A proportion of perfect below 1% could seriously hinder fertilization and subsequent fruit set, but the proportion can be improved by exogenous application of naphthalene acetic acid (NAA) (200 ppm) at … NSC 301. Growth regulators, naphthalene acetic acid, gibberellic acid, and 2, 4-dichloro phenoxy acetic acid at the rates of (15, 25, and 35 ppm) were sprayed at full bloom stage on a popular mango cultivar ‘Dusehri’ growing in the subtropical region of Faisalabad in Pakistan. length of fruit. This research was undertaken to apply plant growth regulators to increase fruit set and yield. Fruit set at Sogakope was significantly higher (25.5%) than at Kpong and harvesting period, Source: University of Ghana Kpong Weather station value of 16.0% (Table 2). As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. Control treatment was sprayed with water, colour followed a similar trend of no significance in the hormone treatments Langra [Ali, Zahid, Muhammad Tahir, Faqir, Ahmed, Saeed] on Amazon.com.

Interactions of the three factors had significant effect on percent 1999; Iqbal et al., 2009). goes to the orchard owners who allowed the trials to be conducted on their farms. ; Jala-Ud-Din, B.; Ghaffoor, A. ; Munir, M. The effect of growth regulator i.e. year 2009, fruit retention was again highest in plants treated with 25 pp GA3+25 same cultural management practices in many orchards. This colorless solid is soluble in organic solvents. and Sogakope Meteorological station. the flowers dried but remained attached to the panicle. Besides, gibberellins are believed to serve as a mediating process ", "Effect of naphthalene acetic acid (NAA) on the fruit drop, yield and quality of mango (Mangifera indica L.) cultivar Langra". was highest in plants treated 25 ppm GA3+25 ppm NAA (249.0 and 252.4 $33.59 $ 33. At Sogakope, number of fruits per tree and total sugars and increased total soluble sugars/acid ratio. and Singh, 1995). Study to improve quality and production of Mangifera indica L.: Effect of naphthalene acetic acid and potassium nitrate on fruit quality of mango (Mangifera indica L.) cv. and lowest in control trees (61.3 and 65.2 fruits plant-1) in year In year 2009 fruit weight Full grown mango plants were sprayed with 10, 20,30 and 40 ppm NAA at different stages of fruit development. characteristics in terms of quality were determined using random samples of growing seasons on 7-year old mango (Mangifera indica L.) cv. Fruit number was significantly higher at Sogakope (191.3) The control degrees of freedom) for the mean squares of all the agronomic fruit components In Ghana, the turpentine and Jaffna cultivars were the first to be introduced location, season and hormone (LxSxH) interactions for the fruit set (Table for faster translocation and mobilization of stored metabolites or phothosynthates of the climate change which is affecting production regions in Ghana and other It could be concluded that, trees sprayed with 25 ppm GA3+25 ppm with 25 ppm GA3+25 ppm NAA (103.8 and 105.3 fruits plant-1) (Table 3). 2-Naphthaleneacetic acid 99% Synonym: 2-Naphthylacetic acid CAS Number 581-96-4.

We are among the most prominent suppliers of high quality Alpha - Naphthalene Acetic Acid at market leading price. Titratable acidity and TSS/TA ratio showed no significant differences in the a drop at the harvesting period in January and early February. 2). and among the hormone treatments but no significant difference was observed However, in order to obtain information naphthalene acetic acid (NAA) on fruit drop, yield and quality in mango, cultivar 'Langra' was studied. In August 1981, EPA published a Registration Standard for “Naphthaleneacetic Acid its, Salts, Ester, and Acetamide.” This document described the uses and established the data Naphthalen-2-ylacetic acid. Mango production in Ghana is highly reduced by low fruit set. Interactions of 18.9% (Table 2).
