ABSTRACT Enau plant (Arenga pinnata Merr) is a type of palma plant that the entire plant can be utilized and potential to be developed. Sungai Naniang is the highest sugar producer in Bukik Barisan Sub-District, with an area of 20 ha. This research aims to find out the morphological characteristics of germplasm enau in Kenagarian Sungai Naniang.This research has been carried out in May to June 2018 with purposive sampling method. The results of the study found 4 variations of the stem color of the entire accession namely dark brown, light brown, grayish brown and grayish brown. The leaves of the enau plant are complete and compound leaves.Based on observations that have been made, there are not many variations in qualitative characters, otherwise many variations are found in quantitative characters. on the entire accession is black with a rough surface. Male flowers are like bullets, they sit in pairs and are purple. Round Female Flower, stand alone, green. Seeds are round in oval shape The number of seeds 3 per fruit and white. Keywords : Enau, Characterization, Morphology, Plant Breeding ABSTRAK Tanaman enau (Arenga pinnata Merr) adalah salah satu jenis tumbuhan palma yang Keseluruhan bagian tanamannya dapat dimanfaatkan dan potensial untuk dikembangkan.

Abstract In the years 2002 − 2004 research was carried out on the effect of onion (Allium cepa L.) ‘Wolska’ bulb size on selected morphological characteristics of seed stalks, seed yield and quality. Commercial bulbs (vernalised, one-year-old mother bulbs) were divided into three groups: small, medium and large, with diameters of 4.2-5.3 cm, 5.4-6.3 cm and 6.4-8.5 cm, respectively. Then, the bulbs of each group were planted in the field and grown routinely with the purpose of producing seeds. The following characters were measured on the seed stalks: number and height of seed stalks grown out from one bulb, the seed stalks’ diameter at the height of 10 cm above the ground, the diameter of the inflorescence, seed yield from a single stalk and from the entire plant, the weight of 1000 seeds, number of seeds in 1 g, length and width of the seeds, length and width of the embryos, and germination energy and capacity. Our experiments showed a significant influence of bulb size on the number of seed stalks and the inflorescence diameter. It was discovered that the big bulbs gave larger numbers of seed stalks than the seed stalks grown from the medium and small ones. Small bulbs gave seed stalks with smaller inflorescences than the medium and large ones. The bulb size had no effect on the seed stalk height or their diameter when measured at the level of 10 cm above the ground. The bulb size also did not affect seed yield per one seed stalk, but it did affect the seed yield obtained from the entire plant, which was bigger for plants grown from large bulbs in comparison with the small ones. The size of the bulbs had no effect on either the weight of 1000 seeds or the number of seeds in 1 g. It did not affect either the seed and embryo length and width or the seed germination energy and capacity.

Mangrove ecosystem is a unique ecosystem with a mix of marine and terrestrial environment. Mangrove forests provide food and nutrients for other organisms such as fish, crustaceans, and algae. Red algae play an important role in maintaining the balance of ecosystems and food chains. This study aims to determine the types, morphological characteristics and key identification, the relationship of red algae types and substrate types to the ecosystem of mangrove forest in Dusun Ekas. This research is explorative descriptive by using purposive sampling method at 5 stations. Based on the results of the red algae study obtained as many as 14 species are: Bostrychia sp., B. radicans, B. tenella, Chondria sp., Laurencia sp., Polysiphonia sp., Murrayella sp., C. Leprieurii, C. Monostica, Gelidium sp ., Gelidium crinale, Catenella caespitosa, Catenella nippae and Catenella sp. Characteristics of the talus were found to have a cylindrical talus and some like leaves (blade). Red algae (Rhodophyta) found more in the station that dominated by Soneratia alba species. Ekosistem mangrove merupakan ekosistem yang unik dengan perpaduan pengaruh lingkungan laut dan daratan. Hutan mangrove menyediakan sumber makanan dan nutrisi untuk organisme lain seperti ikan, crustacea, dan alga. Alga merah berperan penting  menjaga keseimbangan ekosistem dan rantai makanan. Penelitian ini bertujuan untuk mengetahui jenis-jenis, ciri morfologi dan kunci identifikasi, hubungan jenis alga merah dan jenis substratnya pada ekosistem hutan mangrove di Dusun Ekas. Penelitin ini bersifat deskriptif eksploratif dengan menggunakan  metode purposive sampling pada 5 stasiun. Berdasarkan hasil penelitian alga merah yang diperoleh sebanyak 14 spesies yaitu: Bostrychia sp., B. radicans, B. tenella, Chondria sp., Laurencia sp., Polysiphonia sp., Murrayella sp., C. Leprieurii, C. Monostica, Gelidium sp., Gelidium crinale, Catenella caespitosa, Catenella nippae dan Catenella sp. Karakteristik talus yang ditemukan ada yang memiliki talus silindris dan ada yang seperti daun (blade). Alga merah (Rhodophyta) yang ditemukan lebih banyak pada stasiun yang memiliki mangrove jenis Soneratia alba.

The Lut desert is one of the largest and most attractive deserts in Iran. The value of desert tourism remains unclear for Iran’s economy and has only recently been taken into consideration by the authorities, although its true national and international value remains unclear. This study was aimed at investigating the factors that influence tourism development in the Lut desert. Data collected through the purposive sampling method was analyzed using Interpretive Structural Modeling and the MICMAC Analysis. According to the results, cost-effective travel expenses, security, and safety provided in the desert, together with appropriate media advertising and illustration of the Lut desert (branding) are the leading factors that influence tourism in the Lut desert in Iran. This paper highlighted the importance of desert tourism, especially in this region.

In dioecious and monoecious plants that depend on animal vectors for reproduction, pollinators have to be attracted to male and female flowers for pollination to be effective. In the monoecious Cucurbita maxima ssp. andreana, male flowers are produced in greater quantity, are spatially more exposed to pollinators and offer pollen in addition to nectar as floral rewards. Nectar traits were compared between male and female flowers to determine any differences in the characteristics of the main reward offered to pollinators. Nectar chemical composition and sugar proportions were similar between flower types. Total nectar sugar production per female flower was threefold higher than per male flower, and nectar removal did not have any effect on total nectar production in both flower morphs. Pollinators reduced nectar standing crops to similar and very scarce amounts in both flower types. Results indicate indirectly that pollinators are consuming more nectar from female flowers, suggesting that the higher nectar production in female flowers may be a reward-based strategy to achieve the high female reproductive output observed in this species.Key words: Cucurbitaceae, Cucurbita maxima ssp. andreana, nectar production, nectar sugar composition, removal effects, standing crop.
