Tissue culture practices are mostly used to produce true-to-type and virus-free planting material of potato as compared to traditional means. As various plant growth hormones affect the initiation and growth of microtuber, the current experiment was conducted to study the effect of different concentrations of jasmonic acid (JA), kinetin (Kin) and putrescine, either alone or in combination on microtuberization. For this, Murashige and Skoog (MS) medium containing 80 gL<sup>−1</sup> sucrose was supplemented with different concentrations of JA, Kin and putrescine under dark conditions. Overall, twelve treatments (T0 = control, T1 = 10 μM Kin, T2 = 15 μM Kin, T3 = 2.5 μM JA, T4 = 5 μM JA, T5 = 80 gL<sup>−1</sup> putrescene, T6 = 2.5 μM JA + 10 μM Kin, T7 = 2.5 μM JA + 15 μM Kin, T8 = 5 μM JA + 10 μM Kin,T9 = 5 μM JA + 15 μM Kin,T10 = 2.5 μM JA + 15 μM Kin + 80 gL<sup>−1</sup> putrescine, and T11 = 5 μM JA + 10 μM Kin + 80 gL<sup>−1</sup> Putrescine in MS medium) of these biomolecules were supplemented to MS medium. The results indicated that medium T9 (MS + 5 μM JA and 15 μM Kin) significantly increased the microtuberization as well as average number (3.7), size (4.54 mm), fresh weight (503.44 mg) and dry weight (124.77 mg) of microtuber as compared to all other treatment media tested in this study. This might be due to the increased level of tuberonic acid, and its glucosides in the plant also increased due to the exogenous supply of JA that enhanced tuber formation. Hence, this technique can be used and suggested as an efficient microtuber production protocol in potato cv. Desiree at commercial scale to fulfill the requirement of healthy germplasm of potato.</p></div></div>","PeriodicalId":7596,"journal":{"name":"American Journal of Potato Research","volume":"100 2","pages":"184 - 191"},"PeriodicalIF":1.5,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44587429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rapid and accurate biomass estimation is of great significance to potato breeding and agricultural production. However, high cost, large data volume, and poor model scalability are the main problems of hyperspectral remote sensing and LiDAR in existing AGB measurement methods, especially in small-scale farmland. One of the important methods for solving the above problems is extracting canopy structure features through RGB images. In this study, a new AGB estimation method for potatoes at the field scale was proposed by using canopy leaf detection and digital images. First, using the improved feature fusion network and the soft intersection over union (soft-IoU) layer, an improved detection network of dense leaves, DenseNet-potato, was developed to detect canopy leaves. Second, the detection network was used to extract the canopy structural features, and the corrected number and total area of canopy leaves were obtained. Finally, multilayer perceptron (MLP) regression was introduced to build prediction models for AGB using canopy features. It was found that the DenseNet-potato network had excellent detection effects on dense canopy leaves. The mAP<sub>50</sub> and mAP<sub>75</sub> of the two detection pipelines reached 76.63% and 64.35%, respectively, which were 9.17% and 6.05% higher than the state-of-the-art RetinaNet method. In addition, the results indicated a strong correlation between the estimated and field-observed AGB using the MLP method from the digital camera dataset (<i>R</i><sup>2</sup> = 0.83, RMSE = 0.039 kg/plot, NRMSE = 12.16%), while the unmanned aerial vehicle (UAV) dataset was unsatisfactory (<i>R</i><sup>2</sup> = 0.62, RMSE = 0.051 kg/plot, NRMSE = 15.32%). This study can provide a reference for efficiently estimating potato AGB using RGB images.</p></div>","PeriodicalId":7596,"journal":{"name":"American Journal of Potato Research","volume":"100 2","pages":"143 - 162"},"PeriodicalIF":1.5,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41955261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the following year, we again prepared flats of actively growing grass as well as flats with plain potting medium as control. One sprouted tuber of each of 35 jam populations was planted in flats of each of the 12 cheatgrass populations for each treatment: Control, Grass, Straw, and Roots.

The 12 cheatgrass populations inhibited jam tuber shoots compared to Control differently, as Grass (8% to 43% reduction) and as Straw (0% to 33% reduction). Subjective scores of the vigor of cheatgrass and emerged jam stands indicated that a more vigorous stand of cheatgrass is associated with less vigorous jam shoots.

This cross has a low frequency of success and results in seeds of unknown ploidy.

While our models showed high accuracy in determining ploidy, the specificity was insufficient for spectroscopic analysis to be a viable method for ploidy determination.

Proper nitrogen (N) management is essential to producing high tuber yield and good quality while not having detrimental impacts on the environment. Efficient in-season monitoring of plant N status can guide potato growers to apply the right amount of N fertilizer at the right time. The traditional analytical methods for monitoring are destructive, labor-intensive, time-consuming, and have poor spatio-temporal resolution. In comparison, the remote sensing (RS) technologies provide non-destructive assessments with capabilities to cover large areas with high resolution. RS monitoring employs spaceborne, airborne, and ground-based platforms with multispectral or hyperspectral sensors in which physically-based or data-driven models are used to predict and map relevant plant or agronomic measurements. However, most of the research on application of these technologies to potato N management is exploratory and not yet mature. This paper reviews 109 previously published manuscripts to provide a comprehensive review of potato reflectance characteristics, three RS platforms (spaceborne, airborne, and ground-based) and two types of optical sensors (multispectral or hyperspectral), three types of models that can predict potato N status using spectral data, how the modeling process is performed, how RS can contribute to precision N application, and challenges and future outlooks for RS technologies to be applied to commercial N management in potatoes. Overall, RS has the potential for assisting potato growers with understanding the spatio-temporal variation of their crop N status, and fine-tuning their N application to avoid excessive or unnecessary use of fertilizer, so eventually N leaching and groundwater contamination can be reduced.</p></div>","PeriodicalId":7596,"journal":{"name":"American Journal of Potato Research","volume":"100 1","pages":"1 - 14"},"PeriodicalIF":1.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45662426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
