Bark ringing in fruit crops - A review
Get PDFBark ringing or Girdling, a horticultural technique involving the removal of a strip of bark around the trunk or branches of fruit trees, has been widely studied and utilized to influence various aspects of fruit crop management. This practice primarily enhances fruit production, regulates canopy growth, and improves fruit quality. By interrupting the downward flow of nutrients and hormones, girdling can stimulate root development in hardwood cuttings and modify vegetative growth patterns. For instance, it has effectively reduced canopy shoot growth in vigorous apple cultivars, thereby improving fruit yield and quality. Additionally, girdling techniques such as notching and scoring control shoot growth and promote scaffold development in young trees. The method also has implications for nutrient distribution, as it can impact the formation of callus tissue and affect recovery processes. Despite its benefits, girdling can lead to undesirable outcomes, such as basal sprouting below the girdle. This abstract summarizes the critical applications, effects and considerations of girdling in fruit crop management, highlighting its role in optimizing fruit production and tree health
Effect of different packaging methods and storage conditions on postharvest quality and shelf-life of Manila Tamarind (Pithecellobium dulce (Roxb.) Benth.) var. PKM2
Get PDFManila tamarind (Pithecellobium dulce (Roxb.) Benth.), is a dry land fruit crop that belongs to the Fabaceae family commonly known Camacchile or Jungle jilebi. Pithecellobium dulce (Roxb.) has the potential to become productive under harsh climatic and edaphic conditions of dry land areas but its pods have a shorter shelf life. The most important objective was to use proper packaging methods to reduce moisture loss, slow down physiological and biochemical changes and prevent spoilage. The study evaluated 8 packaging methods, including different combinations of CFB (Corrugated Fiberboard) lined with 100-gauge polythene film with 0 %, 5 % and 10 % vents, CFB with 0 %, 5 % and 10 % vents, vacuum packing and a control, under cold storage (13-15 °C) and ambient conditions (26 ± 2 °C). On the 15th day of cold storage conditions, vacuum packing showed minimum physiological loss of weight (19.82 %), titratable acidity (0.68 %), ascorbic acid (77.20) and total sugar (8.36 %). Maximum total soluble solids (15.32 ?Brix), Anthocyanin (22.72 mg 100 g-1 m), shelf life (15 days) followed by CFB with 10 % vent. On the 12th day of ambient storage condition, vacuum packing recorded minimum physiological loss of weight (16.42 %), titratable acidity (0.42 %), ascorbic acid (76.13) and total sugar (8.53 %). Maximum total soluble solids (14.93 ?Brix), Anthocyanin (21.83 mg 100 g-1 m) and shelf life (11.5 days) followed by CFB with 10 % vent. In this study, the overall results indicated that both vacuum packaging and CFB with 10 % vent at cold storage had synergistic effect in manila tamarind fruit pods, not only in extending the shelf life but also maintained the physiological and biochemical attributes of manila tamarind
Sapindaceae fruits: A comprehensive overview on phytochemicals, nutraceuticals and health benefits application
Get PDFThe article delves into the intricate realm of the Sapindaceae family, shedding light on the many phytomedicinal advantages that these fruits offer. This family boasts an array of economically significant fruits, including Litchi (Litchi chinensis), Rambutan (Nephelium lappaceum), Longan (Dimocarpus longan), Guarana (Paullinia cupana), Ackee (Blighia sapida) and Soapberry (Sapindus saponaria), each of which has its own set of medicinal characteristics. The Sapindaceae family, also known as the soapberry family, comprises numerous tropical and subtropical plant species known for their phytochemical properties and potential health benefits. Despite the well-known medicinal properties of Sapindaceae fruits, there is a lack of a comprehensive compilation that combines knowledge about their important components, nutritional value, traditional value and medicinal properties. This review aims to address this gap by providing assessments of the medicinal potential of Sapindaceae fruits and their prospects as food products. The study focuses on the chemicals, nutrients and medicinal properties of Sapindaceae fruits, excluding studies lacking therapeutic relevance. Findings show that Sapindaceae fruits contain bioactive compounds such as saponins, flavonoids and phenolic acids, which are antioxidants, anti-inflammatory, anti-cancer, anti-viral, anti-obesity and anti-diabetic. In addition, these fruits are rich in essential nutrients, including vitamins, minerals and dietary fiber, which supports their use as functional foods and vitamins. The review suggests future research on sustainable uptake and development of nutrients from Sapindaceae, which could increase their use in healthcare and potentially lead to the development of cost-effective pharmaceutical products for consumers and the agricultural sector

Full text linkStandardization of Length of Cuttings and Auxin Levels on Root and Shoot Growth of Dragon Fruit (Hylocereus undatus L.)
No full textDragon fruit as the "Wondrous Fruit" of the twenty-first century is a cactus-like vine with great economic and nutritional potential as exotic fruit crops in domestic and foreign markets. One of the biggest issues with commercial fruit production is the development of high-quality planting materials. Considering that it is a cross-pollinated crop, true-to-type plants could not be obtained through seed propagation. Hence, standardization of vegetative propagation protocol is necessary for commercial production. Therefore the experiment was conducted at Department of Fruit Science, Horticultural College and Research Institute, Periyakulam, to assess different length of stem cuttings (viz., C1 -10cm, C2 – 15cm, C3 – 20cm and C4 - 25 cm) with various concentration of auxin level (viz., G1 – IBA 2000 ppm, G2 – IBA 4000 ppm, G3 - IBA 6000 ppm, G4 – NAA 50 ppm, G5 - NAA 100 ppm, G6 – NAA 150 ppm) for achieving growth and rooting of dragon fruit. According to the experimental findings, among the different treatments 25cm cuttings treated with IBA 6000ppm showed noticeably superior results in early root initiation (12.11 DAP) and sprout initiation (8.26 DAP), highest shoot length (75.52cm) and root length (17.64cm), Average number of roots per cutting (20.17), Average number of shoots per cutting (3.7), maximum survival percentage (93.42%) than other treatments
Engineering resistance against Tobacco streak virus (TSV) in sunflower and tobacco using RNA interference
No full textThe coat protein (CP) gene of Tobacco streak virus (TSV) from sunflower (Helianthus annuus L.) was amplified, cloned and sequenced. A 421 bp fragment of the TSV coat protein gene was amplified and a gene construct encoding the hairpin RNA (hpRNA) of the TSV-CP sequence was made in the plasmid pHANNIBAL. The construct contains sense and antisense CP sequences flanking a 742 bp spacer sequence (Pdk intron) under the control of the constitutive CaMV35S promoter. A 3.6 kb Not I fragment containing the hpRNA cassette (TSV-CP) was isolated from pHANNIBAL and sub-cloned into the binary vector pART27. This chimeric gene construct was then mobilized into Agrobacterium tumefaciens strain LBA4404 via triparental mating using pRK2013 as a helper. Sunflower (cv. Co 4) and tobacco (cv. Petit Havana) plants were transformed with A. tumefaciens strain LBA4404 harbouring the hpRNA cassette and in vitro selection was performed with kanamycin. The integration of the transgene into the genome of the transgenic lines was confirmed by PCR analysis. Infectivity assays with TSV by mechanical sap inoculation demonstrated that both the sunflower and tobacco transgenic lines exhibited resistance to TSV infection and accumulated lower levels of TSV compared with non-transformed controls
