Использование хитозановых препаратов при размножении вишни степной зелёными черенками

Использование хитозановых препаратов при размножении вишни степной зелёными черенками

Abstract

Представлены результаты исследований по размножению сортов вишни степной Селиверстовская и Шадринская способом зелёного черенкования с использованием для об работки черенков традиционного стимулятора корнеобразо-вания индолилмасляной кислоты (ИМК) в качестве эталона и новых хитозановых препаратов и их составляющих (Хорион, Хорион + микроэлементы, ортофосфат калия) при рН 6 и 5. В качестве контроля выступал вариант с предпосадочной обработкой зеленых черенков водой. Черенки сорта Селиверстовская, выдержанные перед посадкой в воде, корней не образовывали, обработанные ИМК окоренялись на 3,0 %, а новыми препаратами на 3,1.13,1 %, у сорта Шадринская окореняемость черенков составила соответственно 43,6, 56,0 и 71,8.90,0 %. На обоих сортах самая высокая величина этого показателя достигалась при более кислой среде растворов. На фоне предпосадочной обработки черенков хитозановы-ми препаратами и ортофосфатом калия отмечено и более интенсивное развитие, как надземной части растений, так и их корневой системы. Например, высота надземной части однолетних саженцев у сорта Селиверстовская изменялась от 12,7 до 16,1 см, у сорта Шадринская от 17,3 до 25,8 см, диаметр условной корневой шейки соответственно от 2,0 до 3,7 мм и от 3,8 до 4,8 мм, количество скелетных корней от 1.0 до 2,7 шт. и от 3,5 до 9,5 шт., средняя длина корней от 4,8до 12,6 см и от 10,9до 18,6см, объем корней от 0,2до 1.1 см 3и от 0,9 до 2,5 см 3.

The influence of cherry green cuttings treatment by different rhizoid stimulators such as conventional IBA and modern chitozan preparation as well as their compounds (Chorion, Chorion + microelements, tribasic potassium phosphate) on propagation coefficient have represented in the article. Treatment of green cuttings by pure water considered as standard variant. It was found out that cuttings of Seliverstovskaya variety have not produced roots by water treatment, 3% by IBA treatment, 3.1-13.1% by modern preparations. From another hand Shadrinskaya variety has provided rooting capacity at 43.6, 56.0 and 71.8-90.0% respectively. Both varieties have provided better results on acidic medium of solution. On the background of preplant treatment of green cuttings by Chitozan and tribasic potassium phosphate it was recorded more vigorous development of both roots and sprouts. Thus, height of one year plants of Seliverstovskaya variety varied from 12.7 to 16.1 cm, as well as Shadrinskaya variety from 17.3 to 25.8 cm. Diameter of root collar varied from 2.0 to 3.7 and from 3.8 to 4.8 mm respectively. Quantity of roots from 1.0 to 2.7 and from 3.5 to 9.5 pcs, average length of roots from 4.8 to 12.6 and from 10.9 to 18.6 cm, volume of roots from 0.2 to 1.1 and from 0.9 to 2.5 cm 3 respectively.
