Description

The objective of this work was to study the effect of Thidiazuron (TDZ) in the in vitro regeneration of rice cultivars. The explants were transferred to MS medium containing different concentration of TDZ. The results indicate that doses were significant on shoot regeneration and growth shoots. For the length of the shoots the interaction cultivar/concentration of TDZ was significant. For the shoots of first passage showing significant differences in the regeneration rate of cultivars, as well as among the concentrations and interaction these factors. All the utilized TDZ concentrations also originated vitrified shoots.

كان الهدف من هذا العمل هو دراسة تأثير ثيديازورون (TDZ) في التجديد المختبري لأصناف الأرز. تم نقل المستكشفات إلى وسط MS يحتوي على تركيزات مختلفة من TDZ. تشير النتائج إلى أن الجرعات كانت كبيرة على تجديد اللقطات وبراعم النمو. بالنسبة لطول البراعم، كان صنف/تركيز تفاعل TDZ كبيرًا. بالنسبة لبراعم الممر الأول التي تظهر اختلافات كبيرة في معدل تجديد الأصناف، وكذلك بين التركيزات والتفاعل، فإن هذه العوامل. جميع تركيزات TDZ المستخدمة نشأت أيضًا براعم مزججة.

L'objectif de ce travail était d'étudier l'effet du Thidiazuron (TDZ) dans la régénération in vitro des cultivars de riz. Les explants ont été transférés dans un milieu MS contenant différentes concentrations de TDZ. Les résultats indiquent que les doses étaient significatives sur la régénération des pousses et les pousses de croissance. Pour la longueur des pousses, l'interaction cultivar/concentration de TDZ était significative. Pour les pousses de premier passage montrant des différences significatives dans le taux de régénération des cultivars, ainsi que parmi les concentrations et les interactions ces facteurs. Toutes les concentrations de TDZ utilisées étaient également à l'origine de pousses vitrifiées.

El objetivo de este trabajo fue estudiar el efecto del tidiazurón (TDZ) en la regeneración in vitro de variedades de arroz. Los explantes se transfirieron a medio MS que contenía diferentes concentraciones de TDZ. Los resultados indican que las dosis fueron significativas en la regeneración de los brotes y el crecimiento de los brotes. Para la longitud de los brotes, la interacción cultivar/concentración de TDZ fue significativa. Para los brotes de primer pasaje muestran diferencias significativas en la tasa de regeneración de los cultivares, así como entre las concentraciones y la interacción de estos factores. Todas las concentraciones de TDZ utilizadas también originaron brotes vitrificados.
