Selection of olive varieties for tolerance to iron chlorosis

Selection of olive varieties for tolerance to iron chlorosis.

Under certain conditions, olive trees grown on calcareous soils suffer from iron chlorosis. In the present study several olive varieties and scion-rootstock combinations were evaluated for their tolerance to iron chlorosis. Plants were grown over several months in pots with a calcareous soil, under two fertilization treatments. These consisted of periodic applications of nutrient solutions cont...

EXCESS PHOSPHORUS and IRON CHLOROSIS

early in the season were less legetative than thobe taken in August and September. The light intensity and light duration to completely keep the standard cultivars vegetatile is 10 to 20 foot-candles for one hour in the middle of the night. A recent experiment on ‘Paul Mikkelsen’ grown at 70’ F revealed that lighting for four hours (10 p.m. to 2 a.m.) with a minimum of 10 foot-candles is necess...

Tolerance to iron chlorosis in non-grafted quince seedlings and in pear grafted onto quince plants

Grafting is a technique that may affect plant tolerance to iron chlorosis in plants cultivated for their fruit. Therefore, the objective of this study was to evaluate the tolerance of non-grafted quince seedlings and pear grafted onto quince plants cultivated in pots with alkaline soil. The experiment was conducted in a greenhouse at the University of Cordoba, Spain, in pots (3 L) filled with a...

Tolerance to Lime - Induced Chlorosis and Drought in Grapevine Rootstocks

Many woody crop plants such as grapevine are traditionally grown with scion varieties grafted onto rootstocks. The selection of an appropriate rootstock provides a powerful tool to manage the growth and fruiting of the scion (Jones, 2012). In the grapevine propagation, the use of rootstocks is not a new matter. The evidence of the use of rootstocks can be found out even in works written by the ...
