Ethylene is a plant hormone with endogenous production associated with the process of senescence for a number of cut flowers. Different stressogenic factors, including signals such as pollination, exogenous ethylene and auxins have been found to be associated with the increase in ethylene emission and a specific tissue response has been documented. The present study was undertaken with the aim ...

The effects of various growing substrates, combinations of soil, silt, sand, press mud (PM) and rice hulls (RH) on plant growth, yield and quality of rose (Rosa hybrida L.) cvs. Kardinal, Anjlique and Gold Medal, were studied to standardize substrates for cut rose production and develop better management and quality production protocol. Plant height, number of leaves branch, leaf area, number o...

Stem and peduncle bending by the weight of the flower is one of the main postharvest problems in gerbera (Gerbera jamesonii Bolus.) and sometimes caused stem crushing or water loss. In this research, silicon and salicylic acid were applied to enhance the mechanical strength of inflorescence stem, and the results revealed that stem curving was decreased by silicon and salicylic acid treatments. ...

In India, Tamil Nadu occupies the first position in terms of area under flower cultivation then followed by Karnataka and West Bengal. Out 33 districts Nadu, Krishnagiri district ranks cut production due to its suitability climatic conditions. The flowers are large cultivated protected conditions (poly greenhouse structure) meet quality standards as expected global trade arena. present study wa...

The aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. Velvet. Hence, an experiment involving the pulsing treatment with gibberllic acid (GA3) at 0, 20, 40 and 60 mg L-1, for 2...

Treatment of daffodil (Narcissus pseudonarcissus) bulbs in a 0.37% formaldehyde water solution at 44 C for 240 minutes is a standard practice in California for management of the stem and bulb nematode, Ditylenchus dipsaci. Recent concern over the safety of formaldehyde and growers' requests for a shorter treatment time prompted a reevaluation of the procedure. The time (Y, in minutes) required ...

This study was conducted to evaluate the effect of preservative solutions on vase life, number of bacteria in the end of stem and in vase solution of cut gerbera 'Double Dutch' and 'Red Explotion'. Cut flowers were pulse-treated with nano-silver (2, 4, 6, 8 or 10 mg L-1) and thymol (12.5, 25, 50, 75 or 100 mg L-1) +5 % sucrose. Experiment was conducted in completely randomized design with 5 rep...
