หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Studies on the formation adDevelopmen of Tangerine’s Embryos) ผู้เขียน:Vatana Satiansavat, Ravee Pachdikulsumpun สื่อสิ่งพิมพ์:pdf AbstractTangerine flowers arise from terminal as well as ateralbuds. The flowers are of perfect and solitary types. The inflorescences arrange cymosely from the terminal branchwith 4-6 petals, 5 sepals, 16-24 stamens and 10-14 carpels. Each carelconsists of 4-5 ovule arranged in the way of axil placentation. The anther consists of two lobes, with two locules in each lobe. The moicrospore tetrad has tetrahedral arrangement and appears as binucleated pollen. The megaspore tetrad has linear arrangement. The mbryo sac develops normally or as the polygonum type in the ovule. The receptive time for stigma is 2-3 days before blooming, and double fertilization occurs 4 days after pollination. The zygote divides 45 days after fertilization and develops into gametic embryo at about the same tim s nucellar embryo development which takn place near the micropylar end. The endosperm develops as the nuclear type. The largest embryo may be either nucellar or gametic embryos. If the nucellar embryo quickly develops and becomes large the gametic embryo may degenerate. The reasons of polymbryo formation in tangerine are:- a) Cleavage of zygote or fission of gametic embryo. b) There are two embryo sac in one ovule and both embryo sacs develop into gametic embryo. c) Nucellus cell divides into nucellar mbryo. d) Budding of nuclear embryo. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Prenatal Development of Gonads in Siamese Crocodile Embryos (Crocodylus siamensis)) ผู้เขียน:วรรณดา สุจริต, ดร.อุไร พงศ์ชัยฤกษ์, ผู้ช่วยศาสตราจารย์, นางสาวผกาวดี พงษ์เกษ, Natanun Prompa, Pibul Ruengsupapichat, ดร.ศิริรักษ์ จันทครุ, ผู้ช่วยศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractIn crocodiles, differentaition of gonads to testis or ovary was influenced by incubation temperatures. To manipulate sexual outcome of the offspring, the information of gonadal development in terms of timing and stages of development is crucial. However, there has been no reports in Siamese crocodiles (Crocodylus siamensis), indigenous fresh water crocodiles of Thailand. This study aims to investigate gonadal development in Siamese crocodile embryos at 35, 48, 63 and 69 days of incubation which belonged to the second half of incubation. Microscopic study of gonad from Siamese crocodile embryos showed the presence of gonadal ridges in embryos at 35 days of incubation, Migration of primordial germ cells was found within gonads at day 35 of incubation and during the same period sex cords were developed. Bipotential gonads were detected at 48 days of incubation and sex cords extensively developed at 63 days and at 69 days of incubation. The data suggested that development of testis and ovary may occur after hatching. Expressions of sex steroid hormones and receptors for sex hormones in Siamese crocodile are needed to be elucidated. |
