(1) "Breeding experiments with Gmelina asiatica indicated total absence of apomixis. Autogamy, geitonogamy and xenogamy all gave fruit-set. But fruit from autogamic pollinations and geitonogamic ones subsequently got abscissed without reaching maturity. The fruit resulting from xenogamic pollinators matured and ripened. Only one ovule developed into seed and the remaining three aborted although the stigmas were pollinated with considerable number of pollen" |

[no mention of type of herbicide]. (2)Badhara bush, however, is tolerant of many herbicides, including picloram, and the soil applied uracils and hexazinone. The most cost-effective treatment available at present is a basal bark spray of ester 2,4-D in diesel oil applied to the plants in January and February. Regrowth from the crown and lateral roots must be treated as it occurs. |
