In vitro flowering and fruiting in tomato (Lycopersicon esculentum Mill.)
In vitro flowering and fruiting were induced in plants regenerated from calli of leaf explants of Lycopersicon esculentum var. Pant 11. MS medium supplemented with 2 mg/l BAP displayed the best response followed by MS with 2 mg/l BAP, 1 mg/ l ABA and 0.5 mg/l IAA. Flower buds were developed both directly from callus and regenerated plantlets from leaf explants under 16 h (39.3 μmol m-2s-1) phot...

Five-week-old tomato plants (Lycopersicon esculentum) cv. Perkoz grown in pots containing garden soil in a growth chamber were submitted to 50 or 150 mM NaCl for 1 h, 2 and 5 days. Tomato leaf anatomy generally did not change after short time salinity, except 5-day-treatment with 150 mM NaCl, where changed cell shape (shrunk and deformed) simultaneously with increased volume of intercellular sp...
متن کاملمطالعه اندام‌زایی گل در گوجه‌فرنگی (Lycopersicon esculentum Mill.)
گوجه‌فرنگی از مهم‌ترین گیاهان باغی و عضوی از تیره سیب‌زمینی است. با وجود اهمیت این گونه به عنوان یک مدل ژنتیکی، اطلاعات اندکی از روند نمو گل در این گونه در دسترس است. در مطالعه حاضر، اندام‌زایی گل در گوجه‌فرنگی توسط میکروسکوپ نوری بازتابشی مطالعه شد. گل‌ها پنج پر بودند و آغازش حلقه‌های گل با الگوی رو به محور و بدون همپوشانی صورت گرفت. آغازش اندام‌ها در هر یک از حلقه‌های کاسبرگ، گلبرگ و پرچم به ...
متن کاملCharacterization of an Ethylene Overproducing Mutant of Tomato (Lycopersicon esculentum Mill. Cultivar VFN8).
Ethylene production rates and tissue ethylene concentrations were determined for the single-gene, Epinastic (Epi) tomato (Lycopersicon esculentum Mill.) mutant, and its parent, cv VFN8. The Epi phenotype was characterized by severe leaf epinasty, thickened stems and petioles, and a compact growth habit. In 4-day-old seedlings, ethylene production was significantly higher in Epi than in VFN8. Et...
متن کاملSeason-controlled changes in biochemical constituents and oxidase enzyme activities in tomato (Lycopersicon esculentum Mill.).
Season-controlled changes in biochemical constituents viz. carotenoids (carotene and xanthophyll) and pectic substances along with IAA-oxidase and polyphenol oxidase (PPO) enzyme activities were estimated/assayed in leaves of Lycopersicon esculentum Mill. (tomato) in two developmental stages--pre-flowering (35 days after sowing) and post-flowering (75 days after sowing) in three different seaso...
