Bottle gourd, a nutrient-rich Cucurbitaceae vegetable, is grown from April to September in Ladakh. However, the favorable environmental conditions for fungal plant pathogens challenge bottle gourd cultivation during this period. During a field survey of the Muth region located at an elevation of 4221 m above sea level, wilting of bottle gourd leaves was observed in August, with a disease incidence of 14% and a severity index of 5%. Isolation and characterization of the pathogen on potato dextrose agar (PDA) medium identified it as Fusarium sp., with typical spores observed under the microscope. The pathogenicity test confirmed the pathogenic nature of the isolate. Amplification and sequencing of the ITS region showed high similarity with Fusarium oxysporum in the UNITE database, and the sequence has been submitted to NCBI GenBank under the accession number OP453355. These findings provide valuable insights into the potential threats of fungal pathogens to bottle gourd cultivation in Ladakh and highlight the importance of disease management strategies in high-altitude regions.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132802727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Failure of fruit set causes the fruit harvest seasonally. Therefore, the aim of this research was to increase off-season production by preventing the failure of fruit set with various exogenous auxin spray. The research was conducted in the snake fruit orchard at Bebandem Sub-District, Karangasem Regency, Bali Province, Indonesia, from February to November 2019. The experiment was designed as a nested factorial with a randomized block design. The treatment consisted of three types of auxin with a specific concentration for each, IAA at 0, 25, 50 and 75 ppm, IBA at 0, 50, 100 and 150 ppm, and NAA at 0, 50, 100 and 150 ppm. The IAA, IBA, and NAA were sprayed on the flowers and leaves 3 times in March, April, and May. The results showed the highest percentage of fruit set, fruit weight per tree, and weight per fruit obtained with IAA treatment were 59.80 %, 2,612.91 g, and 91.06 g, respectively. These results were not statistically different to those of the IBA and NAA. Furthermore, the IAA concentration of 25, 50, and 75 ppm produced a significantly higher percentage of fruit set compared with the control. The increased fruit set in the IAA, IBA and NAA treatments resulted in better yield than the control. The novelty of this result is that spraying snake fruit with IAA, IBA and NAA can prevent the failure of the fruit set. Therefore, IAA, IBA, and NAA are recommended to be applied to increase off-season fruit production of snake fruit.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132544778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current study used markers at DNA level to evaluate genetic diversity and identify whether there are duplicate accessions of Capsicum spp. in the collections of an active germplasm bank. Randomly amplified polymorphic DNA markers using touchdown-polymerase chain reaction method evaluated genetic diversity and identified duplicates in ten accessions of Capsicum spp. Higher genetic diversity has been detected in C. annuum rather than in the species C. chinense and C. baccatum. DNA amplified segments revealed high genetic divergence showing that accessions of C. annuum, C. chinense and C. baccatum were separately grouped after data analysis with three software programs. Accessions of C. baccatum var. pendulum and C. annuum var. glabriusculum were the least similar. Since rates were less than 60% between accessions of C. chinense and C. annuum, they revealed low identity of amplified DNA segments among the three Capsicum species. Redundance in four accessions of C. chinense and in five accessions of C. annuum was not detected. On the other hand, duplicates within accessions C. chinense (50%), C. annuum var. glabrisculum (5%) and C. baccatum var. pendulum (75%) were reported in the Capsicum active germplasm bank.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133717334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This species has been identified in historical documents as being a food crop, although it is not presently grown as a commercial crop. To better facilitate harvest, Passiflora vines must be trellised to keep flowers and fruit off the ground. There are different methods to accomplish this, but there is little consensus as to the best model. Simple trellis systems made from t-posts, wire fencing, and cement blocks were erected onto a crushed rock covered nursery pad. One trellis was made horizontal to the ground roughly 0.3 m off the pad. The other trellis was vertical (perpendicular to the ground) and reached a height of 1.5 m. Three Passiflora species were used: Passiflora caerulea L. (blue passion flower), Passiflora edulis Sims f. flavicarpa O. Deg. (yellow passion fruit), and Passiflora incarnata (maypop). There were no statistically significant differences between vertical and horizontal trellised passion fruit vines in our study. Overall, trellis orientation did not appear to significantly impact vine growth, fruit growth, or fruit quality of Passiflora incarnata. We recommend employing a vertical trellis system for this species.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124612960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The germination of viable pollens to fertilize ovule is influenced by environmental cues such as temperature. The germination and viability of pollen grains collected for pollination purpose also varied with the male pollinizer source and the male spathe opening time. An in vitro study performed to determine the percentage of pollen germination at different temperatures (10, 15, 20, 25, and 30 °C) and germination times (4, 8, 12, and 24 h) taken from different male sources and toidentify any variations in the germination and viability of pollen grains collected from spathes opened at different dates (20th February, 1st and 10th March). Pollens from different male sources showed a significant difference regarding germination percentage when incubated at different temperatures and for different germination times. Pollens incubated at 30 (81.07%) and 25°C (78.17%) had the highest germination percentage which decreased to 51.04, 16.23, and 5.90% when incubation temperature dropped to 20, 15, and 10 °C, respectively. Similarly, 71.11% pollens were germinated after 4 h of incubation at 30°C, which was decreased to 63.26 and 25.40% when incubation temperature decreased to 25 and 20°C, respectively after same time interval. Pollen germination and viability were significantly differed when they were collected from spathes opened at three different dates. Early opened spathes had lowest germination (57.58%) and viability percentages (81.19%) than the middle (81.11 and 91.53%) or late (80.71% and 93.05%) opening spathes. It is therefore, concluded that the optimum temperature for date palm pollen grains germination is 25-30°C and at these temperatures maximum pollens germinated within 4 h. Moreover, pollen grains from early opened spathes were less superior compared to the middle or late opening ones.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114196008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, a field experiment was conducted to evaluate the curd quality of eleven late-season cauliflower varieties. The experiment was set up in a Randomized Complete Block Design (RCBD), with nine hybrid varieties (Freedom, Titan, Ravella, Artica, Bishop, Casper, Indam 9803, NS 106, and Snow Mystique) and two open pollinated varieties (Amazing and Snowball 16). The experiment was carried out over four replications from November 2016 to March 2018. Snowball 16 had the highest TSS value of 5.5 oBrix and pH of 6.5 when compared to other varieties. Snow Mystique had the highest vitamin C content of 48.5 mg/100 g, followed by Amazing and Snowball 16, compared to other varieties. At three, six, and nine days after harvesting, physiological weight loss was 4.0 percent and 8.0 percent in Bishop, and 13.3 percent in Artica, respectively. Snowball 16 received a significantly higher score of 8.5 tasty curds, followed by Amazing. Titan and Artica produced curds with the best appearance and compactness when compared to other varieties. Artica and Titan produced significantly more fresh curds than other varieties. Based on the taste and chemical parameters of the curds for the late winter season in Nepal’s Mid-hill region, it was determined that Amazing was the best OP variety, while Artica, Titan, and Bishop were more preferable hybrid varieties.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124119143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
