Size
of bulbs is directly proportional to the quality of the flower, the commercial
value of the bulb and getting more bulblet. The research was carried out to evaluate the effects
of PGPR on plant
growth parameters,
flowering, bulb quality and bulb mineral contents in hyacinth (Hyacinthus orientalis L. cv. Aiolos) under greenhouse condition. In the study, there were 5 applications: (T1) Pseudomonas
putida strain RCK-42A, (T2) Kluyvera cryocrescens
strain RCK-113C, (T3) Paenibacillus polymyxa strain RCK-12E,
(T4) Bacillus subtilis strain RCK-17C, and (T5) Control (uninoculated
bacteria). The
surface-sterilized bulbs were incubated separately by shaking at 80 rpm for two
hours at 28 ºC to coat the bulbs with the bacteria. The chlorophyll content (50.02), leaf length (26.03 cm), leaf area
(268.38cm2), flower fresh and dry weight (15.54 g and 0.88 g) in T2 (Kluyvera cryocrescens strain RCK-113C) was found as the maximum according to
other applications. The highest leaf width (6.37 cm) and the highest floret number were observed
in T4.
It was shown that the maximum bulb diameter (42.57 mm), bulb length (40.01
mm) and bulb weight (12.01 g)
were determined in T2. The maximum N (2.90%), P (1.98%) and Ca
(1.74%) were found in T3. Maximum Fe (0.48 mg kg-1), Mn
(151.20 mg kg-1) and Zn (35.28 mg kg-1) were found in T1.
Use of especially Kluyvera cryocrescens
strain RCK-113C and Pseudomonas putida
strain RCK-42A bacterial isolates may be effective in maintaining the
sustainability of the environment and growing medium in the cultivation of
hyacinth and also the development of bio fertilizer.
