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...
متن کاملTissue Culture Studies in Tomato (lycopersicon Esculentum) Var. Moneymaker
A protocol was developed for callus induction and regeneration in tomato (Lycopersicon esculentum) var. Moneymaker. Hypocotyl and leaf disc explants of tomato were used as a starting material for callus induction. Explants were cultured on MS medium having different concentrations of hormones. Maximum callogenesis from hypocotyls was obtained on MS medium supplemented with IAA (2 mg/l), NAA (2 ...

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 کاملREGULATION OF CELLULASE AND PECTINASE ACTIVITIES IN CHERRY TOMATO (Lycopersicon esculentum MILL var. cerasiforme) FRUIT BY USE OF 1-METHYLCYCLOPROPENE
Softening, which accompanies ripening fruits is also to a large extent, responsible for the damage that occurs during handling and shipping. The effects of 1-Methylcyclopropene (1-MCP) application at different ripening stages (mature green, breaker, breaker + 2 days and breaker + 4 days) on cellulase and pectinase activities of cherry tomato fruit (Lycopersicon esculentum Mill. var. cerasiforme...
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 ...
