University of Calcutta (informally known as Calcutta University or CU) is a collegiate public state university located in Kolkata, West Bengal, India.&nbsp;Within India it is recognized as a &quot;Five-Star University&quot; and accredited &quot;A&quot; Grade by National Assessment and Accreditation Council.

&nbsp;

The University of Calcutta has secured the Fifth position among the Universities of India in the prestigious &quot;Indian University Ranking 2019&quot; list, released by the NIRF of the Ministry of Human Resource Development, Government of India.

&nbsp;

It was established on 24 January 1857, and was one of the first institutions in Asia to be established as a multidisciplinary and Western-style university. Its alumni and faculty include several heads of state, heads of government, social reformers, prominent artists, only academy award winner and Dirac medal winner in India, many Fellows of the Royal Society and five Nobel laureates as of 2019 which is highest in South Asia.

Structure and Behaviour of Chromosomes as an Aid to the Study of Phylogeny of Umbelliferae with Special Reference to the Tribe Apieae (Ammineae) and Saniculeae

The genus Apium belongs to the subtribe Carinae, of the tribe Ammineae of the family Umbelliferae. It is an important genus of which several varieties have commercial importance and it is widely cultivated. Most of the species of Apium are diploid with 2n=22 chromosomes (Baksay 1956, Bell and Constance 1957, 1966, Beuzenberg and Hair 1963, Gadella and Kliphuis 1966, Hiroe 1955, Mitsukuri and Kurahori 1959, Scheerer 1939, Shah 1953, Sharma and Bhattacharyya 1959, Wullf 1939). Only one triploid species (Whitaker 1941) and one case of 2n=16 have been reported (Richards 1972). In present investigation six varieties have been taken up for their karyomorphological study. © 1977, Japan Mendel Society, International Society of Cytology. All rights reserved.

Artificial polyploidy in coriander (coriandrum sativum l.)

1. Roots from two lots of air-dry seeds of Vicia sativa Linn., that is, i. With twenty-four hours pre-germination soaking in tap water, and ii. Without any such pre-germination soaking were tested cytologically for the study of spontaneous fragmentation in the somatic tissue. 2. Chemicals having no property of causing fragmentation (so-called mutagenic) were used in techniques applied for the detection of fragments, whereas those chemicals having the property of causing fragmentation were used in some sets to study their accelerating or retarding effects on the fragmentation process. 3. Number of fragments noted were found to be one, two, three and even four, but in no case exceeding that number. Fragments were located during all the nuclear phases of the divisional cycle, namely, prophase, metaphase, anaphase and telophase. No significant difference in this behaviour could be noted between seeds germinated after pre-soaking and without presoaking. 4. Gradual degeneration of fragments with increase in age, occurrence of micronuclei and the fate of these fragments and nuclei have been studied and their significance discussed. 5. Data have been gathered to show that possibly the secondary constriction regions are involved in breakage. The susceptibility of secondary constriction regions to breakage has also been regarded as an indication of its chemical difference from the rest of the chromosome segments. © 1956, Japan Mendel Society, International Society of Cytology.
