Abstract:

 


This
study was carried out to determine effects of different PGPR formulations,
chemical fertilizers and their combinations on some plant growth
characteristics of poinsettia under climate-controlled research greenhouse
between July 2015 and July 2017. In the study, rooted cuttings of poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch
cv. Christmas Feelings) were used as plant material. The applications were
created as formulation 1, formulation 2, formulation 3, formulation 4, the full
amount of commonly used chemical fertilizer (100% CF), by combining the reduced
amount of chemical fertilizer by 50% with each bacterial formulation and
control. Plant height, main stem diameter, number of bract, length and diameter
of root, fresh and dry weight of plant were evaluated in the experiment.
According to CF and control applications, BIV+CF application was increased in
the number of bract leaves between 14.76% and 29.32%; and it was also increased
in plant height between 2.87% and 5.27%, respectively. The highest plant fresh
weight (16.93 g) was obtained from BII and CF applications. The highest average
fresh (4.69 g) and dry (1.57 g) plant weight were determined in BII
application. It has been determined that bacterial formulations BIV+CF,
BIII+CF, BIV and BII, which have positive effects on some plant growth and
quality characteristics of poinsettia, can be used in poinsettia production
stage. Thus, bacterial formulations may allow reducing the using chemical
fertilizer in its cultivation.
