Rough lemon (C. jambhiri) is a widely used rootstock possessing most desirable traits with ability to form congenial scionic combinations, but is highly susceptible to foot rot (Naqvi, 2004; Castle, 2010). 0000028012 00000 n More details on rootstock traits can be found in the rootstock selection guide (https://flrootstockselectionguide.org). After sour orange, Rough lemon is the most widely used rootstock in the world. In the last two mentioned countries, selections have recently been named—Estes and Milam—which exhibit resistance to the burrowing nematode. (Jamberi, Jatti Khatti, Mazoe Lemon, Citronelle). Hodgson (1967) additionally noted that: "Although used to some extent as a lemon substitute, for which it is not very suitable, the rough lemon is highly important as a rootstock in many parts of the world—notably India, South Africa, Australia, Argentina, Brazil, and Florida. A tree on a selected rootstock would be rated large[Lg] if it was comparable in vigor and size to one on Cleopatra mandarin or rough lemon, i.e., perhaps 14–20 ft tall. trailer << /Size 141 /Info 97 0 R /Encrypt 104 0 R /Root 103 0 R /Prev 155555 /ID[<32293e56fefdec28a5ab326c29fb0fd7>] >> startxref 0 %%EOF 103 0 obj << /Type /Catalog /Pages 99 0 R /Metadata 101 0 R /Outlines 106 0 R /OpenAction [ 105 0 R /XYZ null null null ] /PageMode /UseOutlines /PageLabels 96 0 R >> endobj 104 0 obj << /Filter /Standard /R 2 /O ( U�V�.�`�����Dz�-���#_m�_�}�g) /U (�w6hh�U+��_ʻ�$\n��ז���/�K�S) /P -4 /V 1 /Length 40 >> endobj 139 0 obj << /S 541 /O 697 /L 713 /Filter /FlateDecode /Length 140 0 R >> stream 0000003977 00000 n Availability: Not commercially available in California.

When grafting lemon trees with the T-bud, the process of breaking apical dominance commonly causes buds on the rootstock to grow in addition to the grafted buds.
