چکیده مقاله :
Eight African marigold varieties including ‘Nari’ (orange), ‘Bindi’ (orange), ‘Bali’ (orange), ‘Little Duck’ (orange), ‘Bali’ (yellow), ‘Bali’ (gold), ‘Little Duck’ (yellow), and ‘Eagle’ (yellow) were comparatively studied for growth habit and flowering quality in open field conditions at the Training Centre for Floriculture and Landscaping, Directorate of Floriculture, Lahore during 2018-2019. Among the varietal study, highly significant variations were recorded for growth habit and flowering parameters. Maximum seed germination percentage (94.5 %) was observed in ‘Bindi’ (orange) followed by ‘Little Duck’ (yellow) with 82.75% germination. ‘Bali’ (orange) took minimum days to 1st bud initiation (21.75 days), which was not significantly different from that of ‘Bindi’ (24 days). Results showed that growth parameters like plant height (11.675 cm), number of buds (22.825), number of branches (34.6), flower diameter (7.9 cm), root length (14.9 cm), and number of roots (30.575) were maximum in ‘Bindi’ whereas ‘Nari’ (orange) showed maximum number of flowers (6.65). Hence, it can be concluded that variety ‘Bindi’ was superior to the other varieties in terms of growth behavior and flower quality in Lahore conditions.
هشت واریته گل جعفری (’ناری‘ (نارنجی)، ’بیندی‘ (نارنجی)، ’بالی‘ (نارنجی)، ’لیتل داک‘ (نارنجی)، ’بالی‘ (زرد)، ’بالی‘ (طلایی)، ’لیتل داک‘ (زرد) و ’ایگل‘ (زرد)) در یک مزرعه رو باز در مرکز پرورشی تخصصی گل و فضای سبز در لاهور پاکستان در سالهای 2019-2018 از نظر عادت رشد و کیفیت گلدهی با هم مقایسه شدند. در بین واریتهها، تفاوتهای معنیداری از نظر عادت رشد و گلدهی ثبت شد. حداکثر درصد جوانهزنی (5/94 درصد) در واریته ’بیندی‘ (نارنجی) و سپس ’لیتل داک‘ (زرد) با 75/82 درصد مشاهده شد. واریتههای ’بالی‘ (نارنجی) و ’بیندی‘ کمترین تعداد روز تا اول گل آغازی (بهترتیب 75/21 روز و 24 روز) را نشان دادند. نتایج نشان داد که پارامترهای رشد مثل ارتفاع گیاه (675/11 سانتیمتر)، تعداد جوانه (825/22)، تعداد شاخه جانبی (6/34)، قطر گل (9/7 سانتیمتر)، طول ریشه (9/14 سانتیمتر) و تعداد ریشه (575/30) در واریته ’بیندی‘ در حداکثر بودند. این در حالی است که واریته ’ناری‘ (نارنجی) بیشترین تعداد گل (65/6) را داشت. بنابراین ما میتوانیم واریته ’بیندی‘ را واریته برتر از نظر رشد و گلدهی در شرایط لاهور معرفی کنیم.
