Degenerations of flag and Schubert varieties to toric varieties
      
In this paper, we prove the degenerations of Schubert varieties in a minusculeG/P, as well as the class of Kempf varieties in the flag varietySL(n)/B, to (normal) toric varieties.
      
As a consequence, we obtain that determinantal varietes degenerate to (normal) toric varieties.
      
We show that wonderful varieties are necessarily spherical (i.e., they are almost homogeneous under any Borel subgroup ofG).

Six Italian clones, P. deltoides cv. I-63, I-69, eramerican hybrids I-72, I-214, I-45 and P. nigra cv. blanc garrone introduced into Jiangsu Province in 1972 recorded a rapid growth, with I 03, I-69 and I-72 being the most outstanding. But, according to our experience, different varieties require different growing conditions: P. deltoides I-63, I-69 and P. euramerican I-72 are best-adapted to warmer regions, while the euramerican hybrids I-214, I-45 and P. nigra blanc de garrone are more adapted to the...

Six Italian clones, P. deltoides cv. I-63, I-69, eramerican hybrids I-72, I-214, I-45 and P. nigra cv. blanc garrone introduced into Jiangsu Province in 1972 recorded a rapid growth, with I 03, I-69 and I-72 being the most outstanding. But, according to our experience, different varieties require different growing conditions: P. deltoides I-63, I-69 and P. euramerican I-72 are best-adapted to warmer regions, while the euramerican hybrids I-214, I-45 and P. nigra blanc de garrone are more adapted to the temperate regions to the north of Changjiang River. As Aigeiros poplars require specific soil conditions for fastgrowing, proper site selection is necessary. Normal growth of black poplar is greatly influenced by four main soil conditions: soil physic: al conditions, moisture availability during growing season, nutrient availability and aeration, which are studied in detail in this paper.

1972年从意大利引入江苏省的黑杨派无性系Ⅰ—63、Ⅰ—69、Ⅰ—72、Ⅰ—45、Ⅰ—214和加龙生长迅速,特别是Ⅰ—63、Ⅰ—69和Ⅰ—72速生性状最为突出,这充分证明这些无性系适合于我省栽培。但由于这些无性系的地理起源不一致,引种到全国有关各地后,在生长上表现很不一致,为了发挥每一无性系的生产潜力,应根据适地适品种的原则,合理选择其适生的气候范围。杨树生长十分迅速,要求较好的立地条件,由于各地区影响立地条件的土壤因子各不相同,所以在选择杨树造林的立地条件时,应根据各地影响立地条件的主导因子来确定适宜栽培的程度。

Based on the experiences of the local peasants and our investigation, tung oil trees in Zhejiang can be classified into 5 local varieties.

油桐地方品种资源的研究,是油桐品种资源利用和油桐品种改良的必要步骤。 本文在总结浙江群众对油桐品种分类的经验和本人对油桐性状变异规律的观察的基础上,把浙江地区的油桐分为座桐、五爪桐、少花吊桐、吊桐和野桐五个地方品种;并对这些地方品种的特性和产量作了初步比较分析,对这些地方品种的利用亦提出了初步方案。

Basing upon the evolution of inflorescence and correlative characters, the author has revised the taxonomic system of Ulmus.The genus Ulmus with over 40 species is chiefly found in the temperate regions of the northern hemisphere, extending to subtropical regions, and southwards to India, the Himalayas, Burma, Laos, Vier-Nam and Mexico. China is situated in the northern hemisphere. It is very rich in species of Ulmus, which are distributed throughout the country. It was found through study that there are 24...

Basing upon the evolution of inflorescence and correlative characters, the author has revised the taxonomic system of Ulmus.The genus Ulmus with over 40 species is chiefly found in the temperate regions of the northern hemisphere, extending to subtropical regions, and southwards to India, the Himalayas, Burma, Laos, Vier-Nam and Mexico. China is situated in the northern hemisphere. It is very rich in species of Ulmus, which are distributed throughout the country. It was found through study that there are 24 species (including the cultivated species) 4 varieties and 5 cultivars.It is quite evident that the genus Ulmus may be divided into two subgenora according to the seasons of their flowering and their position of inflorescence. However, the length of flower-bearing-axis and pedicels, the types of inflorescence and some other characters do not accord with the characters mentioned above.The author agrees with G. Bentham, J. D. Hooker and C. K. Schneider that the genus Ulmus should be divided into sections and not subgenera. The morphological characters do not support the viewpoint of E. Spach and F. Liebmann that sections of Microptslea and Chaetoptelea should be removed from Ulmus and independent genera of Microptelea and Ohaetoptelea should be established. The author concludes that the division and arrangement of the sections in Ulmus should be based on the evolution of inflorescence and correlative characters. Characters of, samara can only be used for dividing series and identifying species. Therefore, the author has revised the taxonomic system of Ulmus; in other words, the genus Ulmus is divided into five sections and six series. They are as follows:Section 1. Chaetoptelea (Liebm.) SchneiderFour species, three found in North America and one in China The section is subdivided into two series.Series 1. Thomasianae L. K. FuOnly one species, U. thomasi Sarg., found in the south-eastern of North America.Series 2. Mexicanae L. K. FuThree species, one, U. elongata L. K. Fu et C. S. Ding, is confined to southern Chekiang and northern Fukien of China, the other two are distributed in North America.Section 2. Trichoptelea SchneiderOnly one species, U. serotina Sarg., found in North America.Section 3. Blepharocarpus DumortierTwo species, all cultivated in China, one, U. leavis Pall., is distributed in Europe, another, U. americana Linn., in North America.Section 4. UlmusThe section contains four series with about 30 species, found in Europe,Asia and North America.Series 1. Villosae L.K. FuOnly one specie, U. villosa Brandis, found in India.Series 2. Glabrae Moss.About 15 species, distributed in Europe, Asia and North America, of which ten species and one variety occur in China.Series 3. Nitentes Moss.About 15 species, found in Europe, Asia and North America, of which seven species and three varieties are distributed in China.Series 4. Lanceaefoliae SchneiderOnly one species, U. lanceaefolia Roxb., found in India, Laos, Burma and China (Yunnan).Section 5. Microptelea (Spach) Benth et Hook.The section has three species, one of which, U. crassifolia Nutt., is distributed in North America, the other two are distributed in India, Viet-Natty KOrea, Japan and China.
