USE OF NATURAL PLANT GROWTH REGULATORS (PGR) IN LARGE-FRUITED

PUMPKIN (Cucurbita maxima Duch.) GROWING TECHNOLOGIES

   

The influence of natural growth regulators on growth, development and yield formation of large-fruited pumpkin (Cucurbita maxima Duch. - Zhdana and Yuvilei) was investigated. PGR influenced reduction in the growing period length, the average weight and fruit formation. The most effective preparations, which can be used in large-fruited pumpkin growing technologies, were chosen.

Research Aim was to study effects of natural growth regulators on large-fruited pumpkin (Cucurbita maxima Duch.) growth and development.

Material and Methods. The investigations were carried out in 2013-2014 on the experimental field of Agronomic Research Station of the Department of Horticulture of National University of Life and Environmental Sciences of Ukraine in large-fruited pumpkins, Zhdana and Yuvilei varieties. During the experiments preparations Biolan, Emistim and Stimpo were investigated. The study was carried out according to the "Test Procedures and Use of pesticides" (2001).

The area of the account field was 50 m, with four-fold replication. Plants were tended according to the conventional technique of large-fruited pumpkin growing.

Results. When the preparations Biolan and Emistim C being used, seedlings of the studied pumpkin varieties emerged one - two days earlier than control ones treated with water. Over the study years the average big fruit weight in Zhdana variety was 6.2 kg and 6.1 kg after use of Stimpo and Emistim C, respectively. There were more fruits after using Emistim C (1.1 pcs / plant).

The average fruit weight in Yuvilei variety was effected by treatment with Emistim C (6.3 kg), however there were more fruits after use of Stimpo and Biolan (1.2-1.1 pcs). A high commercial in Zhdana variety was achieved by using Emistim C 39.2 t / ha (with marketability of 89.5 %) and Stimpo 36.3 t / ha (with marketability of 88.0 %). Yuvilei variety was more productive with Biolan (34.5 t / ha) and Stimpo (36.3 t / ha). Laboratory studies showed that growth regulators affected biochemical composition of pumpkin fruits, especially nitrate content. The most valuable fruits were obtained in Yuvilei variety by using Biolan and Emistim C, which accumulated dry matter 13.8 and 15.3%; total sugar 7.3 and 9.2 %; carotene 9.6 and 12.2 mg / 100 g; vitamin C 20.8 and 22 mg / 100 g, and nitrates - 102.6 and 130.2 mg / kg, respectively.*) Conclusions. The growth regulators Emistim C and Stimpo positively influenced the average fruit weight in Zhdana (6.2-6.1 kg) and Yuvilei (6.3-5.7 kg) varieties. Zhdana variety was highly yielding after using Emistim C (39.2 t / ha) and Stimpo (36.3 t / ha); Yuvilei variety gave

37.0 t / ha and 34.5 t / ha after using Stimpo and Biolan, respectively. Use of the plant growth regulators did not significantly affect biochemical composition of fruits. The most valuable fruits were produced in the variants Yuvilei + Biolan or Emistim C.

* In other varieties nitrate contents were below the maximum permissible level (below 200 mg / kg) 633.854.78:631.582
