“…Inthichack et al (2012) found that intensification of tipburn symptoms in lettuce may occur as a the result of increasing salinity caused by fertilization with potassium salts. High potassium level also increased tipburn injuries in Chinese cabbage and decreased calcium uptake (Borkowski & Szwonek 1994). In our experiments, ____________________________________________________________________________________________________________________ mass tipburn on Chinese cabbage appeared in condition of strong solar irradiation and low air humidity.…”

“…A high temperature and low humidity that prevailed in June 2008 caused very high tipburn injury and as a consequence, rotting of heads. The best results in all sequential investigations were obtained with foliar application with 1.5% calcium nitrate or 1.5% Wapnovit containing calcium, which is indispensable for tipburn prevention (Borkowski & Szwonek 1994;Saure 1998;Olle & Bender 2009). It is interesting that Tytanit and Wapnovit used separately diminished markedly tipburn appearance, but applicated as the mixture in the same term and conditions strongly augmented the symptoms of this disorder.…”

“…Advantageous effect of calcium nitrate on Chinese cabbage has been known for many years (Borkowski & Szwonek 1994;Borkowski et al 2006). When the day temperature is 30 °C or more, the best results were received with foliar application of calcium nitrate mixed with Biochikol 020 PC (Borkowski et al 2007).…”

Investigations were carried out in 2008-2010 on Chinese cabbage (Brassica rapaL. var.pekinensis(Lour.) Olson). The main problem in cultivation of this vegetable is physiological disorder – tipburn. It is connected with low level of calcium in young leaves and with water deficiency. In 2008, seeds of Chinese cabbage were sown twice, in April and July. In July, the day temperature was high (25-30 °C) and relative air humidity was low (35-50%). In these conditions, the young leaves were injured heavily. Rotting was caused by the activity of bacteriaPectobacterium carotovorumsubsp.carotovorum(Jones) Hauben et al. However, three times foliar application of 1.5% calcium nitrate or 1.5% Wapnovit significantly reduced the tipburn. Also spraying with 0.03% of Tytanit (containing ions of titanium) or with 2.5% of Biochikol 020 PC (containing chitosan) gave similar effect. In these conditions, application of 1.5% K-300 (containing potassium oxide and ammonium nitrate) exacerbated symptoms of tipburn. Application of Wapnovit or Tytanit reduced instantly rotting of heads contrary to the application of their mixture. In autumn cultivation, when the relative air humidity was 80-100%, spraying with 1.5% solution of K-300 significantly decreased injuries in comparison to control. Application of Wapnovit, K-300, Biochikol, Tytanit or the mixture of Biochikol and calcium nitrate eliminated rotting. In experiments done in the springs of 2009 and 2010, when weather conditions were less favorable for tipburn appearance, a severity of it was lower but application of K-300 increased it appearance. In these experiments, Biochikol and Wapnovit eliminated rotting of heads. The results of three years of study have shown that calcium nitrate, Wapnovit, Tytanit and Biochikol limited occurrence of tipburn and bacterial rotting of Chinese cabbage, but the weather conditions during cultivation had the greatest impact on the severity of tipburn.

“…Also, the foliar application of calcium salts (Gruebesck & Zandstra 1988) can be useful, primarily against margin rot, although efficiency is poor after the plant has begun head formation. Tipburn incidence is more severe when environmental conditions induce high growth rates (Borkowski & Szwonek 1994;Gaudreau et al 1994;Stratton & Nagata 1994;Balvoll 1995), necessitating a greater Ca flow. As a prevention for this problem, growth regulators have been tested, such as paclobutrazol in lettuce (Obispo 1997) or chlormequat (Maroto et al 1996) and daminozide (Aloni 1986) in Chinese cabbage, although results have proven inconsistent (Saure 1998).…”

Row covers of polypropylene sheeting have been studied in relation to the quality in Chinese cabbage (Brassica rapa subsp. Pekinensis 'Nagaoka 50') for 3 years (1999, 2000, and 2001) in the area of Granada, Spain, under a Mediterranean continental temperate climate, on 55-day cycles with transplanting in mid March. The mean commercial yield for the 3 years was 11.9 kg m -2 under row covers, but only 2.1 kg m -2 in open air, owing primarily to the important number of non-commercial cabbages. The cabbages grown in the open air were exposed to lower temperatures than under covers and showed a higher number of plants with bolting and plants lost in the field. The better thermal regime under the covers and the least vapour pressure deficit favoured heading, reducing the number of malformed cabbages. The foliar calcium (Ca) content in the outer leaves was significantly greater in the open air than under the row cover, whereas the reverse was true in the inner leaves. These lower Ca contents in the inner leaves of the open air plants, encouraged tipburn. The use of the row cover constitutes a lowcost technique to improve open air spring cultivation of this leafy vegetable in this type of Mediterranean continental climate.
