    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 349-365, 2019, DOI:10.32604/phyton.2019.08406
    Abstract The increasing deforestation with an alarming rate is the prime cause of upsetting the balance in the natural ecosystem and the livelihood of local communities. Sustainable forest management and reforestation efforts can equilibrium this destruction and maintain the protected areas. In this regard, soil management strategies for reforestation of the degraded forest land can be helpful. In this review, the potential of using biochar, a solid carbon rich product of biomass thermochemical conversion, as a soil amendment in forest soils has been discussed. The production procedures of biochar, availability of feedstocks and the biochar properties are discussed using the existing… More >

    Effects of Particle Matters on Plant: A Review

    Lijuan Kong1,2, Haiye Yu1,2, Meichen Chen1,2, Zhaojia Piao1,2, Jingmin Dang1, Yuanyuan Sui1,2,*
    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 367-378, 2019, DOI:10.32604/phyton.2019.09017
    Abstract The particle matter, particularly the suspended particle matter (PM ≤ 2.5) in the air is not only a risk factor for human health, but also affects the survival and physiological features of plants. Plants show advantages in the adsorption of particle matter, while the factors, such as the leaf shape, leaf distribution density and leaf surface microstructure, such as grooves, folds, stomata, flocculent projections, micro-roughness, long fuzz, short pubescence, wax and secretory products, appeared to play an important role determing their absorption capacity. In this paper, the research progress on the capture or adsorption of atmospheric particles was summarized, and… More >

    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 379-388, 2019, DOI:10.32604/phyton.2019.04784
    Abstract Application of biochar to agricultural soils is mostly used to improve soil fertility. Experimental treatments were comprised of two factors: i) drought at two level, i.e., 80% and 40% water holding capacity (WHC) which was maintained on gravimetric basis ii) three levels of biochar i.e., control, 2 t ha-1 and 4 t ha-1 added to soil. Experimentation was done to examine potential of biochar application to enhance the growth attributes, water relations, photosynthetic pigments and antioxidants activities in maize (Zea mays L.) seedlings. Results of study revealed that biochar application increased the growth qualities (total seedlings biomass, dry weight of… More >

    Pseudogamous Apomixis in Maize and Sorghum in Diploid-Tetraploid Crosses

    Marina Tsvetova1, Lev Elkonin1,*, Yulia Italianskaya1
    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 389-401, 2019, DOI:10.32604/phyton.2019.07485
    Abstract Apomictic seed development is a complex process including formation of unreduced embryo sac, parthenogenetic embryo development from the egg cell, and endosperm formation either autonomously, or due to fertilization of polar nuclei by the sperm (under pseudogamous form of apomixis). In the latter case, an obstacle to the normal endosperm development is disturbance of maternal (m) -to-paternal (p) genomic ratio 2m: 1p that occurs in the cases of pollination of unreduced embryo sac with haploid sperms. Usage of tetraploid pollinators can overcome this problem because in such crosses maternal-to-paternal genomic ratio is 4m: 2p that provides formation of kernels with… More >

    Amylose Content and Starch Granule Size in Rice Grains are Affected By Growing Season

    Hengdong Zhang1, Min Huang1,*, YingjuanWei2, Jiana Chen1, Shuanglü Shan1, Fangbo Cao1, Guanghui Chen1, Yingbin Zou1
    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 403-412, 2019, DOI:10.32604/phyton.2019.07371
    Abstract Amylose content and starch granule size in grains influence rice quality, which differs between the early (ES) and late season (LS). The objective of this study was to determine the variation of amylose content and starch granule size between seasons and find the main reasons (e.g., temperature and solar radiation) for the observed variation. Field experiments with six rice varieties (three high and three low amylose content rice) planted in the ES and LS were conducted in 2016 and 2017, respectively. The mean temperatures during the filling stage were higher in ES, however, the daily temperatures at 7-10 days after… More >

    The Allelopathic Effects of Sunflower and Wheat Root Exudates on Sinapis arvensis and Sinapis alba

    Bengu Turkyilmaz Unal1,*, Mustafa Bayram2
    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 413-423, 2019, DOI:10.32604/phyton.2019.08244
    Abstract In this study, we aimed to investigate the allelopathic effects of sunflower and wheat root exudates on the common weeds such as wild mustard and white mustard in our region. The root exudates which were obtained by soaking 8 weeks old sunflower and wheat seedlings (20 or 40 seedlings) in 100 mL of distilled water for 3 days were applied to the leaves of wild mustard and white mustard. In order to compare the allelopathic effect, the recommended dose (1 g.da-1 ) and twice the recommended dose (2 g.da-1 ) of Gromstor (Tribenuron-methyl), a herbicide preferred by farmers for the… More >

    Association Analysis of the Growth of Black Poplar (Populus Nigra L.) Under Contrasting Nitrogen Levels

    Xihua Liu1, Changjun Ding2, Xiaohua Su2,*
    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 425-433, 2019, DOI:10.32604/phyton.2019.08285
    Abstract The European black poplar (Populus nigra L.) has been used as a germplasm resource for the breeding of new poplar varieties around the world. The identification and screening of its high nitrogen use efficiency genotypes could enable the breeding of new resource-efficient poplar varieties. The accessions were screened using MALDI-TOF MS genotyping technology for ammonium transporter (AMT) and nitrate transporters (NRT) genes against phenotypic data for seedling height and ground diameter traits, in both low and high nitrogen environments. Allele re-sequencing of seven genes related to root development was carried out using the minisequencing method. By cluster analysis, 101 accessions… More >

    Juan Isidro Sánchez-Duarte1, David Guadalupe Reta-Sánchez1,*, José Antonio Cueto-Wong1, Arturo Reyes-González1, Esmeralda Ochoa-Martínez1
    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 435-448, 2019, DOI:10.32604/phyton.2019.07512
    Abstract Canola and oat forage potential may be affected by climatic conditions when sown early. The objective of this study was to evaluate the forage canola and oat potential in four early sowing dates (September 11 and 25; October 9 and 23) during the 2012-2013 and 2013-2014 cycles in Matamoros, Coahuila, Mexico. Growth cycle duration, chemical composition, dry matter (DM), crude protein (CP), and net energy for lactation (NEL) yields were determined. High temperatures and long photoperiods affected crops seeded on September 11, accelerating growth and reducing canola (26.6%-31.7%) and oat (15.8%) DM yields. As of September 25, canola cv IMC… More >

    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 449-458, 2019, DOI:10.32604/phyton.2019.06350
    Abstract Tomato crops (Physalis ixocarpa Brot.) are produced in almost all Mexico, part of the United States and Central America. Recently the tomato production has suffered economic losses of 70% to 80% due the presence of yellowing and floral abortion, whose causal agent has been attributed to the presence of phytoplasma; an insect vector of these phytoplasma is Bactericera cockerrelli Sulc. Alternative control of this psyllid has lacked effectiveness because their spatial distribution is unknown within tomato plots. This study aimed to determine the spatial distribution of populations of nymphs of B. cockerelli in four tomato plots, the determination of the… More >

    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 459-470, 2019, DOI:10.32604/phyton.2019.07719
    Abstract Fertilizers industry faces the challenge of improving the efficiency of its products either by optimizing the fertilizers in use or by developing new types of them. During the last decade, controlled and slow release technologies have become more important. These technologies aim to increase the efficiency of the applied substance by increasing its action over time and avoiding losses of all kinds (leaching, volatilization). The main purpose of the current study was to obtain a slow release biofertilizer by incorporating microalgae into a polymeric ureaformaldehyde matrix (PUFM). The quantitative analysis of macronutrients and micronutrients in the microalgae was determined using… More >
