چکیده مقاله :
Floriculture is among Kenya’s top foreign exchange earners. Gladiolus is one of the four famous cut flowers in the world whose popularity in Kenya is attributed to its heat tolerance, many spike forms and color combinations. However, the perishable nature of the flower renders it vulnerable to huge post-harvest losses. The study aimed to evaluate pulsing effect of cut Gladiolus grandiflorus ‘Fado’ with 600 ppm 8-hydroxyquinoline sulfate plus 5 % sucrose prior to wet cold storage duration (0 – 5 days) on quality and vase life against the control (distilled water). The Gladiolus were grown in the open field from corms at the Horticulture Research and Teaching Field, in the Department of Crops, Horticulture and Soils, Egerton University, Kenya, during two successive seasons. A two by six factorial experiment embedded in a completely randomized design with four replicates was adopted. Pro GLM model in two way ANOVA was used to determine differences using Tukey’s test at 5 % level of significance. Pulsing treatment had significant effects on the Gladiolus quality parameters including: Fresh weight (P = 0.0031; 82.214 ± 0.7934 g) as compared to the control; dry weight (P = 0.0272); interactive effect of the pulsing and cold storage duration treatments (P = 0.0004); maximum vase life (11.5 ± 0.287 days) and opened florets (11 ± 0.15). The highest number of unopened buds (5.18 ± 0.212) were recorded in the control which also had least mean water uptake (23.87± 0.26 ml) as compared with the pulsed and cold stored spikes (31.98 ± 0.193 ml). Pulsed cold stored Gladiolus preserved quality up to 4 days. The knowledge gained from this study will augment existing technologies in improving quality and market value of this cut flower.
گلکاری در بین 10 تجارت اول خارجی کنیا است. گلایل یکی از 4 گل بریده مشهور در دنیاست که محبوبیت زیادی به خاطر تحمل گرما و شکل و رنگ های متنوع دارد. البته ماهیت فسادپذیری و زوال در این گل، باعث کاهش عمر پس از برداشت آن شده است. هدف آزمایش ارزیابی اثر تیمار پالس 600 میلی گرم در لیتر 8-هیدروکسی کینولین سولفات همراه با 5 درصد ساکارز قبل از انبار سرد مرطوب (0-5 روز) روی کیفیت و عمر گلجایی گل شاخه بریده گلایل رقم ’فادو‘ در مقایسه با شاهد (آب مقطر) است. کاشت پداژههای گلایل در مزرعه آموزشی و تحقیقاتی باغبانی در گروه تولیدات گیاهی باغبانی و خاکشناسی دانشگاه اگرتون در کنیا انجام شد. آزمایش در 2 فصل اجرا شد. یک آزمایش 2 تا 6 عاملی بر پایه طرح کاملا تصادفی با 4 تکرار طراحی شد. مدل Pro GLM به شکل تجزیه واریانس دو مرحله ای و آزمون مقایسه میانگین توکی در سطح آماری 5 درصد استفاده شد. تیمار پالس اثرات معنی داری روی پارامترهای کیفی گلایل نسبت به شاهد مثل: وزن تر (7934/0 ± 214/82 گرم)؛ وزن خشک (P=0.0272) داشت. اثر متقابل پالس و انبار سرد مرطوب باعث حداکثر عمر گلجایی (287/0 ± 5/11 روز) و گلچه های باز (15/0 ± 11) شد. بیشترین جوانه باز نشده (212/0 ±18/5) در گیاهان شاهد ثبت شد. این گیاهان کمترین جذب آب (26/0 ±87/23 میلیلیتر) را در مقایسه با پالس و انبار سرد (193/0 ± 98/31 میلیلیتر) داشتند. گل های تیمار پالس در انبار سرد کیفیت خود را تا 4 روز حفظ کردند. داده های این آزمایش بیان میدارند که این تکنولوژی میتواند کیفیت و ارزش تجاری این گل ها را بهبود ببخشد.
