 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Callus Induction and Plant Regeneration from Mature Embryos of Glutinous Rice (Oryza sativa L.) Cultivar TDK1) ผู้เขียน:Souvanh THADAVONG, ดร.ประภา ศรีพิจิตต์, รองศาสตราจารย์ , ดร.วาสนา วงษ์ใหญ่, รองศาสตราจารย์ , ดร.พีรนุช จอมพุก, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe present study was conducted to determine the optimum in vitro conditions for callus induction and plant regeneration from mature embryos (seeds) of glutinous rice cultivar TDK 1. It was revealed that embryos cultured on Murashige and Skoog (MS) agar medium supplemented with 2 mg/l 2,4-D and 500 mg/l L-proline under light condition produced the highest percentage of callus formation (96.91 %). The average size of callus produced was large (6.02 mm). The calli dehydrated by placing in petridishes with covers for 7 days under light condition before transferring onto regeneration medium generated higher frequency of shoot regeneration than the calli cultured on regeneration medium without dehydration. The most suitable medium for plant regeneration from dehydrated calli was MS agar medium supplemented with 1 mg/l IAA, 4 mg/l BA and 800 mg/l casein hydrolysate which induced the highest percentage of calli forming shoots (45.00 %) and each callus produced the largest number of shoots (average 15 shoots). The shoots were rooted at the highest rate (100 %) when transferred onto MS agar medium supplemented with 1 mg/l NAA. The complete plantlets were thereafter transplanted to grow under greenhouse condition. They were morphologically normal and fertile. |
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. |
