[Method] Tomato seedlings were grafted with Guozhenl (T1) and Solanum torvum (T2) as the rootstock, respectively. Self-rooted tomato seedlings were treated as the control (CK). The resistance of tomato against root knot nematodes was compared among the three treatments. [Result] Compared with those in the T2 and CK groups, the yield of tomato in the T1 group was increased by 17 436.75 and 31 753.65 kg/hm2 respectively, the plant height was increased by 10.55 and 14.54 cm respectively (P〈0.05), and the stem diameter was increased by 0.56 and 1.13 cm respectively (P〈0.05). The disease indexes of root knot nematodiasis in the three treatments were 0.55, 10.42 and 45.31, respectively, and there were significant differences among them (P〈0.05). [Conclusion] This study will provide a theoretical basis for the control of root knot nematodes in tomato by grafting.展开更多

He created a solid legal basis for the country and regulated the ecclesiastic area. He was in West Georgia in 1329-1332/1333. The llkhanid coin was not minted in Georgia during that period; yet, soon the king of Georgia, which had already been united by that time, restored relations with llkhanids and returned to Tbilisi, which implied making the already united Georgia subject to Mongols. Ilkhanid coins and later, coins of Chobanids, the Golden Horde and Jalayirids circulated during the reign of George the Brdhant. In 1338-1339 George the Brilliant conquered Ossetia and Ilkhanid coins were disseminated on the territory of the Golden Horde after that. Formally, Georgia remained under the control of Ilkhanids, which was replaced by Chobanids in 1338 and the governors of the Golden Horde in 757/1356; and in parallel and afterwards by Jalayirids, which is evidenced by written sources as well as numismatic data; Despite formal dependence on the foreign power, which is evidenced by the deployment of 10,000 troops at the border of Georgia as well, the country enjoyed a rather wide internal autonomy. Participation of George the Brilliant in sending envoys for the purpose of the redemption of the Jvari (Cross) Monastery in Palestine in 1316/7, 1320 cannot be assumed. It seems that in those years envoys were sent by Constantine, the king of West Georgia. All the above do not diminish the merits of George V to the Georgian nation and his historic role in terms of the political unification of the country, the creation of a legal basis for it and the regulation of ecclesiastic affairs--the accomplishments of the king, who deservedly bears the name "the Brilliant".展开更多
