Kinetin was found to induce anthocyanin formation in green ‘Manzanillo’ olives and to promote softening slightly. A concn effect in promoting the pigment was found up to 50 ppm. The duration of kinetin treatment affected the amount of anthocyanin formed. The kinetin effect on anthocyanin formation appeared to be independent of that on softening.
Morphactin in spray oil and butanol as emulsifier applied to the bark of grapevine (Vitis vinifera L.) trunks caused girdling effects. Treatment of ‘Thompson Seedless’ after fruit set increased berry size and treatment of ‘Perlette’ and ‘Muscat of Hamburg’ before harvest advanced maturation. A comparison between chemical and mechanical girdling showed that the former was somewhat less effective than the latter.
Treatment with a 0.5-2% cyanamide (H2NCN) solution for 5 min effectively substituted for chilling in seed of four Vitis vinifera L. cultivars, allowing immediate germination. Treatment could shorten the breeding cycle.
