Wedgewood. A mixture of sand and clay (1:1 v/v) was prepared as a growth media. The treatments were (0, 25, and 50 % water drought) with liquid active biostimulants (garlic and seaweed) five times intervals after two weeks from bulb germination. The results revealed that plants at different soil moisture with various biostimulants succeeded in producing flowers of the best quality. Water drought at 25% also increased chlorophyll (a & b) and carotenoids in leaves, while drought at 0% recorded the highest increase in gibberellic acid. At 25% drought, vegetative growth and flower parameters were at their highest levels. Moreover, water drought at 50 % increased abscisic acid (ABA), proline, and catalase. Additionally, increases in vegetative growth, the number of leaves, flower parameters, chlorophyll (a & b), and carotenoids in leaves were noted as a result of applying seaweed extract at a concentration of 10 mL L-1; however, the best results for gibberellic acid were obtained using the highest concentration of garlic extract (500 mL L-1). The interactions between treatments indicated the superiority of growing bulbs at 25 % water drought with applying seaweed extracted at 10 mL L-1 that improved vegetative growth and most of the flower parameters. Meanwhile, treating plants at 25 % water drought with either seaweed at 5 mL L-1 or garlic extract at 500 mL L-1 realized the higher chlorophyll (a & b), carotenoids, and gibberellic acid (GA3) content.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121304256","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}

Therefore, flowering biology and fruiting phenology study were carried out on field-established G. tenax plants in Kachchh, Gujarat, from February - March 2018. Flowers are scented and cream-white with yellow stamens and composed of 5 petals and sepals, an ovary and a style, 2 anther lobes and many anthers (66.33 ± 7.51). Bud initiation started in the last week of February and anthesis was observed after 6.40 ± 0.18 days of bud initiation. Flower anthesis start at 1130 h and is completed at 1330 h, with peak anthesis during 1215-1230 h in February. On an average, 15.55±0.98 and 19.55±0.98 days are required for fruit maturity and ripening. The study revealed that the fruit traits of the white cross berries, including fruit length and diameter, varied within the ranges of 4.93-6.69 mm and 4.06-5.91 mm, respectively. As there is limited information available on this species, these findings provide a foundation for further genetic research on white cross berries. This study can serve as a valuable resource for future investigations aiming to enhance our understanding of the genetic makeup of this species and potentially improve its fruit traits through breeding programs.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121555598","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}

Induction of polyploidy can help to restore fertility by doubling of chromosomes and thus leading to the creation of allotetraploids which can help breeders develop improved hybrids and novel types by contributing beautiful floral or growth characteristics unobtainable from the diploid forms. The objective of the present study was to investigate the effective colchicine concentration and duration of exposure for the polyploidy induction in Dendrobium crumenatum via in vivo method, thus improving the flower characteristics. For the in vivo induction of polyploidy, D. crumenatum plantlets were chosen and subjected to eight different colchicine treatments. Treatments were based on colchicine concentration (0.05 and 0.1%) and the duration of exposure of plantlets to these doses of colchicine (24, 48, 72 and 96 hrs). The morphological characters, like shoot length, diameter of pseudobulb, number of leaves and width of leaves showed treatment mean values greater than their corresponding control plantlets. After analyzing the histogram peaks of in vivo treated samples, it was observed that the highest tetraploid induction (50%) was achieved with the treatment of 0.05% colchicine for 96 hours. Moreover, the maximum mixoploids (66.67%) were obtained from two different treatments; first, with 0.05% colchicine for 72 hours and second, with 0.05% colchicine for 48 hours. These results suggest that longer treatment duration of 96 hours with 0.05% colchicine leads to higher tetraploid induction while shorter durations of 72 and 48 hours with the same concentration of colchicine are more effective for producing mixoploids. Stomatal observations exhibited a lower stomatal density, but increased stomatal size in polyploids than diploids.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114589011","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}

Results revealed that the incidence of midge among the genotypes varied significantly (F29, 58 = 25.88; P< 0.00). The lowest incidence was recorded on Neelgoa (16.15%) followed by Neeleshan (26.1%) and the highest in Alphanso (86.27%), Totapuri (86.42%), H-39(87.39%), Amrapali (88.69%), and Lalsundari (89.48%). Based on the relative susceptibility of the genotypes (percent damage to blossom), genotypes were grouped in different categories. Every variety retained the fruits irrespective level of plant damage to the floral bud, having diverse genetic potential the fruit weight had no correlation with fruit number. The impact studies of midge control measure in Amrapali revealed that the floral damage in untreated plants ranged between 73.69-91.37 percent and 61.47-75.47 percent in treated trees. The fruit number at the harvesting stage ranged between 2.80-4.00/ panicle and 3.1-4.20/ panicle with a fruit weight ranging from 1.10 -1.43 and 1.23-1.50 kg/panicle, respectively.It was concluded that though the percent flower damage, fruit number, and yield per panicle differed significantly in treated and untreated trees, this statistical significance may not be of great economic importance at the maturity stage as 3-4 fruits per bunch in Amrapali gives standard yield.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123706009","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}

In the present study, the accuracy of a module for camera warm-up times of 30 sec, 1 min, 2 min, 3 min, 3.5 min, and 4 min was compared when leaf temperature was periodically measured using a Lepton 3.5 module, a low-cost thermal imaging camera. The experiment was conducted for a plant in a laboratory, and a high-accuracy LT-1T thermistor sensor was used together to compare module accuracy. The power consumption of both sensors decreased by using the sleep mode of the module, and all measurements were conducted in intervals of five minutes. The accuracy was compared using the R-Squared, MAE, and RMSE of the two values measured by LT-1T and Lepton 3.5. As a result of the experiment, the accuracy was the highest when the warm-up time was 3.5 minutes showing the mean absolute error (MAE) and the root means squared error (RMSE) values of 0.56 ? and 0.59 ?, respectively. The accuracy was 2.5%, which was substantially higher than the 5% accuracy of the device specification.","PeriodicalId":290245,"journal":{"name":"The Journal of Applied Horticulture","volume":"28 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126831626","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}
