Platanus acerifolia (Aiton) Willd was generated spontaneously around the beginning of the 1600s in Spain between Platanus orientalis L. and Platanus occidentalis L. The study was carried out on P. acerifolia trees in different sites in Rome in the period April-July 2019. Trees comparable for size were selected in A sites (historical parks), B sites (high traffic density streets) and in C sites (high traffic density avenues along the Tevere River characterized by a large water availability). At the morphological level, leaf area (LA) was significantly higher in A and C sites and leaf tissue density (LTD) in C sites. At anatomical level, the total leaf thickness (LT), the palisade parenchyma thickness (Pt), the spongy parenchyma thickness (St) and the abaxial epidermis thickness (Abet) were significantly higher in A sites, while the adaxial cuticle thickness (Adct) and the adaxial epidermis thickness (Adet) in B sites. The ratio between palisade and spongy parenchyma thickness (P/S) was significantly higher in C sites. The plasticity index (PI, 0.42) was calculated on all the considered leaf traits. Among the morphological traits, LTD had the highest plasticity (0.49) and among the anatomical traits, trichomes density (TD) and Adet (0.74 and 0.54, respectively). Overall, the results highlight the large adaptability of P. acerifolia to grow in different sites in Rome through several changes in leaf morphological and anatomical traits.
在17世纪初左右，西班牙的Platanus orientalis L.和Platanus occidentalis L.之间自发产生了Platanus acerifolia (Aiton) wild。研究于2019年4月- 7月在罗马不同地点的P. acerifolia树木上进行。在A地点(历史公园)，B地点(高交通密度街道)和C地点(沿Tevere河的高交通密度大道，其特点是大量的水可用性)中选择了大小相当的树木。在形态水平上，A和C位点的叶面积(LA)和C位点的叶组织密度(LTD)显著高于其他位点。在解剖水平上，A位点的叶片总厚度(LT)、栏状薄壁厚度(Pt)、海绵状薄壁厚度(St)和下表皮厚度(Abet)显著高于B位点的近轴角质层厚度(Adct)和近轴表皮厚度(Adet)。栅栏厚度与海绵状薄壁厚度之比(P/S)显著高于C位点。计算各叶片性状的可塑性指数(PI, 0.42)。在形态性状中，LTD可塑性最高(0.49)，在解剖性状中，毛密度(TD)和Adet分别为0.74和0.54。综上所述，研究结果表明，通过叶片形态和解剖特征的变化，针叶树对罗马不同地点的生长具有较大的适应性。

Lar National Park, one of the most beautiful plains, 70 km east of Tehran on Haraz Road, is one of the protected areas of Iran which is located on the border of Tehran and Mazandaran provinces. Since Lar National Park is protected by the Environment Organization and for this reason, any harvesting of plants or entry of some areas is prohibited, so this study was conducted to prepare a list and vegetative form of some of its plants for the knowledge of botanists which relates to a small part of Lar National Park. For the floristic study of this part of the region, samples were collected from June to September in 2017-2018, which 30 family were identified. The floristic study of plants in the Lar region shows that 3 families have the highest frequency. Also, our result is compared with the Poloor region in which two areas were close to each other in terms of the dry season. In terms of plant species identification, it shows that the Lar plain region as Poloor region is one of the largest families of the region Astraceae, Poaceae and Lamiaceae, study of biological form and chorology, and frequency of three families in Lar region and compares it with the adjacent area which is Poloor.

Nuphar lutea (L.) Smith (Nymphaeaceae) is a widespread hydrophyte with leaves floating on the water. This highly productive plant forms a fairly large assimilating (photosynthesizing) surface. The purpose of this work was to develop a method for calculating the surface area of assimilating leaves of N. lutea. As a result, the formulas for calculating the surface area of a leaf (main photosynthetic organ of N. lutea) were obtained. The area formulas for the blade and petiole are based on the area formulas for geometrical figures and allow us to calculate the assimilating surface area of the yellow water-lily as precisely as possible. Therefore, the data obtained provide a better picture of this species productivity and will allow further to estimate the contribution of this species to the overall productivity of water bodies and watercourses

The paper presents the results of the study dedicated to the investigation of sweet corn leaf apparatus growth and development in dependence to the crop cultivation technology elements, viz. depth of plowing, mineral fertilizers application doses, plants density, in the drip-irrigated conditions of the South of Ukraine. The field trials were carried out during three years (2014-2016) by using the split-plot design method in four replications with accordance to the modern requirements of the experimental work in agronomy. The results of the study showed the significant effect of all the studied agro technological treatments on the crop leaf apparatus. The highest Leaf Area Index (LAI) that averaged to 3.72 was obtained under moldboard plowing at the depth of 20-22 cm, fertilization with N120P120, and plants density of 80000 ha-1. The total amplitude of fluctuation of LAI averaged to 2.42. Increased plowing depth improved LAI of sweet corn only under the non-fertilized conditions, however, increased fertilizers doses and thickening of the crops positively affected the studied bio-metric index.

Symphyotrichum squamatum (Spreng.) G.L.Nesom, is an erect herb of the Compositae family, recorded from the campus of the Shiv Nadar University, Uttar Pradesh, India. The species is being recorded for the first time from India as there are no earlier reports of its occurrence in the literature. The taxonomic description of the plant along with colored illustrations of morphological characteristics such as habit, leaf, flower, root etc. are provided for easy identification of the species in wild. As the plant is known to have a tendency to spread rapidly, it may become an aggressive weed in India in near future.

The effect of pre-sowing seed treatment with inoculant and its combination with a plant growth stimulant in terms of the optimization of the level of soil acidity on the formation of symbiotic plant productivity and the accumulation of biological nitrogen in the soil has been studied. On the basis of the results obtained it has been found that the use of pre-sowing treatment of alfalfa seeds with rhizobophyte in combination with Emistym S against the background of soil liming and the application of the full rate of lime subject to hydrolytic acidity provides the accumulation of the largest amount of biologically fixed nitrogen. This is on average over the years of research has run at 236.1 kg/ha.

Purpose of the research was to identify the pathogenic agent, to study its trophic specialization in the context of introduction of plants of the genus Liriodendron L. For the first time in Ukraine, affection of leaves and branches with anthracnose Colletotrichum gloesporioides (Penz.) Pens. & Sacc. was detected on Liriodendron chinense. Affected leaves turn yellow and fall prematurely. It was established that the highest development of the disease (7.3%) was observed in 2014, which was determined by favourable weather conditions (hydrothermal coefficient (HTC) 2.0 in April and 1.7 in May). Period 2013, 2015 was characterized by a significantly lower manifestation of anthracnose and became 2.2%, 2.6%, respectively. With a strong development of the disease, infection is observed in the branches as well-the bark darkens in the places of affection, the cambium dies off, the branch dries out. For the protection of plants against anthracnose, agro technical measures are recommended, as well as the use of fungicides. It should be noted that since the first signs of the disease it takes about 10-15 days until the death of the leaves. With the strong development of the disease, the infection of branches is observed as well. The use of Champion and Chorus preparations to protect the Liriodendron chinense against anthracnose showed that their effectiveness is high, and the development of the disease have decreased to 0.3% and is not harmful.

A Philippine specimen of Plagiostachys albiflora Ridl. (Zingiberaceae) which was previously recorded only from the Malay Peninsula and Borneo was recently discovered in Mt. Malambo, Brgy. Datu Salumay, Marilog District, Davao City, Philippines. The specimen, described herein, constitutes the first record of the said species in the Philippines. Further, P. albiflora is the only non-endemic species among the Philippine Plagiostachys and is an addition to the seven known endemic species in the country. Existing populations of the species are rare and under severe threats due to anthropogenic activities and therefore call for immediate conservation initiatives.

The results highlight significant variations of Wollemia nobilis leaf traits which reflect age-related changes of the subsequent growth units along the branches. Age-related changes appear in a gradual increase of leaf size from young leaves to old leaves. The LMA increasing from 13.75 g/cm2 in current year leaves to 24.84 g/cm2 in 7 year leaves is associated with an increment of the number of lignified elements (vascular tissues, astrosclereids), of hypodermal and epidermal-cuticle structures (cuticle, wax layer) and of oil bodies abundance, which may increase resistance to stress factors. These characteristics highlight that W. nobilis leaves can adapt to variable environmental conditions with a return rate on a larger time-scale since leaves on a branch stay alive for a long time until the branch dies.

Evaluated the possibility of organizing the biosynthesis of plant adaptogens-flavonoids from the standpoint of the theory of neutrality. We assumed that the biosynthesis of flavonoids and low-molecular compounds with similar physicochemical properties is neutral with respect to microfluctuations of environmental conditions. Leaf extracts Chamaedaphne calyculata (L.) Moench from natural populations oligotrophic swamps the Middle Ob region (Western Siberia) was studied by method HPLC-high performance liquid chromatography. The samples to carry out the HPLC analyses were taken in ecologically equivalent swamp areas. Chromatograms differed in the number of peaks, the time of their release, and the area of particular peaks. The hierarchy constructing procedure from single up to "combined" chromatograms, where peaks from 1, 2, 3, 5, and 9 chromatograms were placed on the common time scale of the peaks release, was carried out for fractal analysis. The number of peaks varied from 21-30 in particular chromatograms up to 76 peaks in a "generalized" united chromatogram. The complex of calculation procedures has shown that all chromatograms obtained from Chamaedaphne calyculata plants are stochastic fractals, where the independent variables are the number, the size (area) and release time of each particular peak. In the presence of the fractal properties of the flavonoid system, it is necessary to analyze the possibility of implementing both neutral and deterministic variants of the synthesis of this or that flavonoid.
