Mathematical modeling of the growth and development of potatoes (Solanum tuberosum L.) / by Keith T. Ingram.

As an important nongrain crop, the growth and yield of potato (Solanum tuberosum L.) is often affected by an unfavorable external environment in the process of cultivation. The MYB family is one of the largest and most important gene families, participating in the regulation of plant growth and development and response to abiotic stresses. Several MYB genes in potato that regulate anthocyanin synthesis and participate in abiotic stress responses have been identified. To identify all Solanum tuberosum L. MYB (StMYB) genes involved in hormone or stress responses to potentially regulate potato growth and development, we identified the MYB gene family at the genome-wide level. In this work, 158 StMYB genes were found in the potato genome. According to the amino acid sequence of the MYB domain and gene structure, the StMYB genes were divided into R2R3-MYB and R1R2R3-MYB families, and the R2R3-MYB family was divided into 20 subgroups (SGs). The expression of 21 StMYB genes from different SGs in roots, stems, leaves, flowers, shoots, stolons, young tubers, and mature tubers was determined by quantitative real-time polymerase chain reaction (qRT-PCR). The expression patterns of StMYB genes in potatoes treated with abscisic acid (ABA), indole-3-acetic acid (IAA), gibberellin acid 3 (GA3), NaCl, mannitol, and heat were also measured. We have identified several potential candidate genes that regulate the synthesis of potato flavonoids or participate in hormone or stress responses. This work provides a comprehensive understanding of the MYB family in potato and will lay a foundation for the future investigation of the potential functions of StMYB genes in the growth and development of potato.

A field experiment was conducted at Allahabad in order to evaluate the performance of different Potato (Solanum tuberosum L.) varieties under the climatic conditions of Northern Plains of India.The experiment was carried out for two consecutive years i.e., during 2015-16 and 2016-17to assess the morphology, physiological behaviour of these potato varieties/strains under a similar set of agro-climatic conditions. All the potato varieties/strainsviz.E-4486,JI-5857, JI-1804, JI-1808, JG-224, JG-657,JE-808, JF-110, JF-27, JF-547,JG-1134, Fr/B-10, JH-222, EM/H- 1601,JF-4864, JF-5106, JF-4915,JH-49,JH-516,JI-5871,FR-B-4,FR-B-4,FR/B-21,FR.B-105,G-2524,Kufri Sheetman, Kufri Chandramukhi, Kufri Bahar, Kufri Lalima, Kufri Badshah, Kufri Jyoti, Kufri Alankar and Kufri Sinduri were replicated thrice under randomized block design. Important information on different aspects like tuber sprouting, plant growth and development and yield was gathered in all the treatments.Potato variety JH-222 was the best performer followed by JG-224, E-4486, JF-547, Kufri Bahar, FR/B-10, Kufri Badshah, JF-110, Kufri Chandramukhi, EM/H-1601, Kufri Alankar, JF-27, JG-1334 and JE-808.

The study aimed to explore the impacts of distinctive qualities of the LED light (such as to low power consumption, lesser production costs, longer operational lifetime and cool light emission with specific monochromatic wavelength) on potato (Solanum tuberosum L.) growth and development including plant height, number of leaves, root length, fresh and dry weight etc. The accumulation of phyto-pigments, soluble proteins and sugars, free radical scavenging activity and overall tuber yield were also evaluated. Enhanced plant height with increased diameter and branching was observed with the plant growing under the B100 and R30B70 LED light combination. Similarly, total number of leaves, leaf surface area, health index, phyto-pigments and tuber yield of potato was also significantly increased as compared to the plant growing under the W100 as control. Soluble proteins and sugar content and free radical scavenging enzyme activity were also significantly enhanced in the R30B70 LED light combination. Tubers yield per plants were also enhanced under the RB combination of the LED light. The current study indicated that the combination of R and B LED lights proved better for plant growth and development in a controlled environment and the R30B70 is the best combinational spectra for increased growth and tuber yield of potato plants. Therefore, the precise management of the irradiance and wavelength may hold promise in maximizing the economic efficiency of potato production, and quality of this important vegetables grown in controlled environments.
