TL;DR: UV-B exclusion could be a useful tool forphysiologists and molecular biologists to further address mechanisms involved in UV-Bradiation damage in crop plants.
Abstract: UV-B radiation affects crop plants. Growing interest has been shown in studying the effectsof UV-B radiation exclusion on crops since 1993. This article summarized the generalconsequences of UV-B radiation exclusion on crop plants from the aspacts of plant morphology,growth and development. UV-B exlusion has promoting effects on plant height, internodeand leaf size. UV-B exclusion increases root biomass and stimulates nodulation of legumecrops with increased number and size of nodules and enhances the leghemoglobin. Higherlevels of α-tocopherol is found in UV-B plants, which plays an important role in translocatingphotoassimilates from the leaves to the roots. UV-B exclusion could be a useful tool forphysiologists and molecular biologists to further address mechanisms involved in UV-Bradiation damage in crop plants.

TL;DR: The plantlets regenerated in vitro with well-developed shoots and roots were successfully established in pots containing humus, sand and garden soil (2:1:1) and grown in a greenhouse with a 90% survival rate.
Abstract: Begonia (Begonia rex Putz.), an ornamental plant, is used for landscape and pot purposes. For efficient regeneration of this species, a simple protocol is presented. Leaf explants dissected from 7-month-old mother plants grown in a greenhouse were cultured on Murashige and Skoog (MS) medium supplemented with 16 combinations of 6-benzylaminopurine (BA; 0.00, 0.50, 0.60 and 1.00 mg l -1 ) and α-naphthaleneacetic acid (NAA; 0.00, 0.10, 0.25 and 0.50 mg l-1). Here, we present a protocol includes single medium for maximum induction and growth of all traits related to micropropagation of begonia. The optimum plant growth regulators (PGRs) for maximal shoot number (44.33 per plant), node number (12.31 per plant), leaf number (76.25 per plant), root number (11.42 per plant), and root length (6.00 cm per plant) were 0.50 mg l-1 BA + 0.10 mg l-1 NAA. The plantlets regenerated in vitro with well-developed shoots and roots were successfully established in pots containing humus, sand and garden soil (2:1:1) and grown in a greenhouse with a 90% survival rate. The regenerated plants were morphologically identical to the mother plants. The described protocol offers a simple and fast protocol for micropropagation of begonia for large-scale multiplication.

TL;DR: Based on the exploration of the germplasm of Eriobotrya Lindl.
Abstract: Based on the exploration of the germplasm of Eriobotrya Lindl. in China and observation and comparison of the plant morphology of collected species and varieties, the description of the characteristics of leaf, shoot, branch, flower and fruit of different species of Eriobotrya was supplemented or renewed. The main characteristics of the leaf, flower and fruit of E. kwangsiensis Chun was also briefly described. At the same time, some index on leaf in Eriobotrya plants were investigated, recorded and statistically analyzed, and the means of leaf traits investigation and date record were discussed.

TL;DR: According to the results obtained, AgNO3 led to shorter plant heights in some varieties, and the yellowing and wrinkling seen in the leaves of plants after Agno3 applications of 750 and 1000 ppm doses, which disappeared over time.
Abstract: Silver nitrate (AgNO3) is a frequently used chemical in several areas in agriculture including control of plant growth, flowering development and dormancy. This study was conducted to investigate the effects of AgNO3 on the morphology of cucumbers. The experiments of this study were carried out in a plastic greenhouse in Antalya/Turkiye during the spring and fall of the breeding periods. AgNO3 application was performed by spraying it on the growth tips of plants. The following doses (0, 250, 500, 750, 1000 ppm AgNO3 doses) were administered to the plants. The research was conducted four times each time the applications were administered to the plants. In order to determine the effects of the applications, the heights of plants and the effects of planting periods on vegetative characteristics were determined and the results were statistically evaluated. According to the results obtained in this study, AgNO3 led to shorter plant heights in some varieties, and the yellowing and wrinkling seen in the leaves of plants after AgNO3 applications of 750 and 1000 ppm doses, which disappeared over time. In the light of the results obtained, when researchers want to use the applications of AgNO3 in their studies, they should be careful at all times and arrange the doses correctly for longer plant life. Key words: Cucumis sativus L., silver nitrate, plant morphology.

TL;DR: DNA analysis confirmed that genotypic differences associated with leaf shape exist among dandelion plants collected at the Lethbridge Research Centre, and the biotypes had different metal concentrations, which may be a concern if plants are sampled to monitor metal contamination.
Abstract: Dandelion plants at the Lethbridge Research Centre, Alberta, have several different leaf shapes and possibly include individuals that are tolerant to glyphosate. The objectives of this study were to determine whether different leaf shapes are due to genotypic differences, whether chemical composition varies with leaf shape, and whether plants vary in their response to glyphosate. Plants with possible glyphosate tolerance were collected in 1998 from a pasture field where forage grasses were terminated with glyphosate, and from an alfalfa (Medicago sativa L.) field where no herbicides had been applied. Image analysis of plants that were progeny of the original collection indicated that they have significantly different leaf shapes. DNA analysis confirmed that genotypic differences associated with leaf shape exist among dandelion plants collected at the Lethbridge Research Centre. The biotypes had different metal concentrations, which may be a concern if plants are sampled to monitor metal contamination. All...
